♨️ Gecko TSC-8 / K-8 Electronic Keypad with Two Overlays (0200-007194) — 8-Button LCD Spa Side Control with Filtration Cycle Button for Gecko M-CLASS and S-CLASS Systems

Genuine Gecko Alliance OEM 8-button LCD keypad — bundled kit including TWO overlays (9916-100130 M-CLASS 8-button and 9916-100331 S-CLASS 7-button) for cross-compatibility with both Gecko M-CLASS and S-CLASS spa systems. Includes dedicated filtration cycle button for time-based filter scheduling.

📋 Product Overview

The Gecko Alliance TSC-8 / K-8 with two overlays (part number 0200-007194) is the manufacturer’s 8-button LCD primary keypad bundled kit designed for Gecko M-CLASS spa control systems with cross-compatibility for S-CLASS systems through the included alternate overlay. Also marketed as TSC-8-GE1, TSC-8-GE2, K-8, BDLTSC8GE1, BDLTSC8GE2, and through Gecko’s Spa Builders / SpaBuilders private-label channel, this is a service-grade replacement keypad with an unusually flexible bundling — BOTH the 8-button M-CLASS overlay (9916-100130) AND the 7-button S-CLASS variant overlay (9916-100331) are included — letting buyers configure the keypad for either spa pack architecture as needed.

The TSC-8’s defining UX feature is its dedicated filtration cycle button combined with dedicated Power button, making it a more advanced primary keypad than the TSC-4 sibling: Pump 1 / Pump 2 / Blower / Light / Power / Filter / Temp+ / Temp- (with the M-CLASS 8-button overlay). The dedicated Filter button provides direct access to filtration cycle programming — supporting daily filter schedules, on-demand filter cycles, and integration with Economy/Standard modes. The 7″ × 3-1/4″ rectangular form factor with rounded sides shares its physical body with the TSC-4 sibling, making cabinet replacement straightforward when upgrading from older Gecko M-CLASS service panels.

This 0200-007194 listing connects through an 8-pin JST plug with 10-foot cable to Gecko’s M-CLASS or S-CLASS spa pack. Compatible Gecko circuit boards include 0201-300045 and 0201-300014 (for M-CLASS) plus 59-337-1250 and 59-337-1260 cross-references. The TSC-8 directly replaces the older TSC-14 keypad and consolidates multiple older Gecko service references including 0200-007072, 0200-007113, 301763, 9735-261, BDLTS8CGE1, BDLTSC8GE1, BDLTSC8GE2, and TSC-8-PPD. The internal keypad-only SKU (without overlays) is 0200-007113. Used as factory-original on Coleman / Maax Spas (cross-reference 104522) and as a direct replacement for proprietary Hawkeye Spas K-8 (3-00-7052) topside controls. Important: This is NOT a modern Gecko in.Link keypad — it’s the older M-CLASS / S-CLASS architecture with 8-pin JST connector. Verify your spa’s control system before ordering. Genuine Gecko Alliance OEM, manufacturer warranty.

• ❌ Pneumatic / air-button (Tecmark Command Center, EasyPak) systems

⚠️ Compatibility Verification: The TSC-8 uses a specific 8-pin JST plug designed for M-CLASS / S-CLASS spa pack ports. If your existing keypad has an in.Link connector, RJ45 (Ethernet-style) plug, Molex connector, 4-pin or 6-pin connector, or 8-pin white flat plug, your spa pack is NOT compatible with this TSC-8.

How to Verify Compatibility:

📍 Open your spa cabinet and locate the spa pack — look for a Gecko Alliance label and confirm it’s an M-CLASS or S-CLASS model 📍 Check that your existing keypad cable has an 8-Pin JST plug (NOT in.Link, NOT RJ45, NOT Molex) 📍 Compare your existing keypad’s circuit board number to the compatible list (0201-300045, 0201-300014, 59-337-1250, 59-337-1260) 📍 Compare your old keypad dimensions to 7″ × 3-1/4″ 📍 Verify your old keypad has 8 buttons with the layout: Pump 1 / Pump 2 / Blower / Light / Power / Filter / Temp+ / Temp- (M-CLASS) OR 7 buttons (S-CLASS) 📍 Look for any of the older part numbers (0200-007072, 0200-007113, 301763, BDLTSC8GE1, BDLTSC8GE2, TSC-14) on your existing keypad 📍 Coleman / Maax Spas owners — check for cross-reference 104522 📍 Hawkeye Spas owners — this can replace the proprietary 3-00-7052 K-8 topside 📍 If you have a 3-pump spa, you may need the TSC-8-10K (0201-007153) instead — verify pump count 📍 Determine whether your spa pack is M-CLASS or S-CLASS so you can apply the correct included overlay 📍 Contact Parts4Tubs with your spa pack model number and circuit board number if you’re unsure

🔘 Button Functions & Display

The TSC-8 has 8 physical buttons. The two included overlays provide different function mappings depending on your spa pack architecture:

M-CLASS 8-Button Standard Layout (Overlay 9916-100130):

Button	Function
Pump 1	Jet pump 1 on/off (and 2-speed cycle if applicable)
Pump 2	Jet pump 2 on/off (and 2-speed cycle if applicable)
Blower	Spa blower on/off
Light	Spa light on/off
Power	System power state — instant access to main power
Filter	Direct access to filtration cycle programming
Temp+	Increase set water temperature
Temp-	Decrease set water temperature

S-CLASS 7-Button Alternative Layout (Overlay 9916-100331):

Button	Function
Pump 1	Jet pump 1 on/off
Pump 2	Jet pump 2 on/off
Light	Spa light on/off
Blower	Spa blower on/off
Economy Mode	Toggle Economy Mode
Temp+	Increase set water temperature
Temp-	Decrease set water temperature

📌 The TSC-8’s defining UX feature is the combination of dedicated Power and Filter buttons for direct access to system power state and filtration scheduling — making it a more advanced primary keypad than the TSC-4 sibling. The TSC-4 has Mode and Prog buttons but lacks the dedicated Filter button. Choose the TSC-8 if filtration control is important to your usage; choose the TSC-4 if mode-cycling and programming flexibility matter more.

LCD Display:

The TSC-8’s LCD display shows:

Display Element	Shows
Temperature digits	Current and set water temperature
Pump 1, Pump 2 indicators	Active state for each jet pump
Blower indicator	Spa blower active state
Light state	Spa light on/off
Heater state	Heater energized status
Filter cycle	Filtration scheduling status
Mode indicator	Standard / Economy / Sleep mode status
Power state	System power on/standby
Error codes	Diagnostic codes from the M-CLASS / S-CLASS spa pack

Filtration Cycle Programming:

The TSC-8’s dedicated Filter button is a distinctive feature — providing direct access to filtration cycle programming without menu navigation. Press the Filter button to:

• View current filtration schedule
• Set daily filter cycle start time
• Set filter cycle duration
• Trigger manual on-demand filter cycle
• Configure additional filtration parameters

This is more accessible than keypads that require multi-button programming sequences for filter configuration.

🛠️ Installation Guide

Before Installation:

• ⚠️ Disconnect power at the GFCI breaker before any work
• ⚠️ Confirm your spa pack is a Gecko M-CLASS or S-CLASS system with one of the compatible circuit boards (0201-300045, 0201-300014, 59-337-1250, 59-337-1260)
• ⚠️ Verify the 10-foot cable will reach from the keypad cutout to the spa pack
• ⚠️ Verify the existing connector is 8-Pin JST plug (NOT in.Link, NOT RJ45, NOT Molex)
• ⚠️ Confirm your spa shell cutout accommodates a 7″ × 3-1/4″ rectangular keypad
• ⚠️ Determine which overlay you need: 9916-100130 (M-CLASS 8-button) OR 9916-100331 (S-CLASS 7-button)

Installation Steps:

1. Power Down — Turn off all power to your hot tub at the GFCI / disconnect (safety first)
2. Open the spa cabinet and locate the 8-pin JST cable on the M-CLASS / S-CLASS spa pack
3. Disconnect the old keypad cable from the spa pack’s keypad port
4. Remove the old keypad from the spa shell cutout
5. Prepare the Surface — Clean the mounting area thoroughly with rubbing alcohol and allow it to dry completely
6. Choose the correct overlay — 9916-100130 for M-CLASS systems (8-button) or 9916-100331 for S-CLASS systems (7-button)
7. Apply the chosen overlay to the keypad face — align carefully over the button positions and LCD display window
8. Route the new cable through the cabinet to the spa pack
9. Plug the new 8-pin JST connector into the spa pack’s keypad port
10. Apply silicone sealant around the keypad edge if recommended by your spa manufacturer
11. Mount the new keypad in the spa shell cutout — press firmly into place
12. Restore power at the breaker
13. Test all functions — All buttons (per applied overlay layout); verify LCD display lights up clearly with temperature and indicators operating; confirm all spa functions activate

Mounting:

Requirement	Specification
Panel size	7″ × 3-1/4″ (rectangle)
Mounting type	Drop-in / surface-mounted with sealant

⚠️ Professional installation by a competent individual or tradesman trained in spa equipment is recommended. All work must comply with the National Electrical Code (NEC) and local codes. Topside controls cannot be returned once opened or installed — verify fitment before opening packaging. Save the unused overlay in a safe place — you may want to convert overlay variants in the future or transfer ownership of the keypad to a different system later.

⚡ Wiring & Connection

Connector Information:

Specification	Detail
Connector Type	8-Pin JST Plug (M-CLASS / S-CLASS specific)
Cable Length	10 ft (~3 m)
System Voltage	Low-voltage signal — works with both 120V and 240V M-CLASS / S-CLASS spa pack configurations

Connection Location:

Plugs into the 8-pin JST keypad port on Gecko M-CLASS or S-CLASS spa packs.
The connector is specific to M-CLASS / S-CLASS architecture and is NOT
interchangeable with modern Gecko in.Link, RJ45, or Molex connectors.
Compatible circuit boards: 0201-300045, 0201-300014, 59-337-1250, 59-337-1260.

⚠️ Never force the connector. The 8-pin JST plug should slide in cleanly. If it doesn’t fit, your spa pack may use the modern in.Link connector (use a Y-Series/X-Series keypad like in.k200, in.k300, in.k450, etc.), be a Balboa system (RJ45/Molex), be a Dimension One @Home/SSPA system (different JST 8-Pin variant — use 01560-345), or use vintage D1 MSPA architecture (4-pin + 6-pin — use TSC-24 / 01580-0001) — verify before proceeding.

🔍 Troubleshooting

Common Issues:

Problem	Possible Cause	Solution
Blank LCD display	No power or loose connection	Verify breaker on; reseat the 8-pin JST plug at the spa pack
Error codes shown	M-CLASS / S-CLASS spa pack issue (sensor, flow, heater)	Refer to your spa pack TechBook for code meanings
Buttons unresponsive	Worn overlay or moisture intrusion	Inspect overlay for wear or water damage
Wrong functions when buttons pressed	Wrong overlay applied for spa pack architecture	Verify overlay matches your spa pack: 9916-100130 for M-CLASS, 9916-100331 for S-CLASS
LCD icons missing or partial	Display fault	Replacement may be needed
Foggy display	Internal moisture from a failed seal	Replace the keypad; check overlay seal
Pump 1 or Pump 2 button doesn’t activate pump	M-CLASS / S-CLASS pump configuration issue	Verify spa pack pump output is enabled
Blower button doesn’t activate blower	Spa configured without blower output	Verify spa pack has blower output enabled
Filter button doesn’t access menu	Wrong button combination or firmware	Refer to TSC-8 documentation for filter programming sequence

Power button doesn’t toggle system	Spa pack power configuration	Verify M-CLASS / S-CLASS firmware supports keypad power control

Error Codes:

Error codes are generated by the M-CLASS / S-CLASS spa pack, not the keypad.
Refer to your specific Gecko M-CLASS or S-CLASS system manual for code definitions.
Common codes: HL (high limit), HH (heater high), Sn (sensor), FL (flow).

🔧 Maintenance & Care

Routine Care:

Task	Frequency
Wipe keypad face with damp cloth	Weekly
Check button response (all 8 or 7 buttons depending on applied overlay)	Monthly
Verify LCD display	Monthly
Verify each Pump and Blower button controls respective output	Monthly
Verify Filter button accesses filtration menu	Monthly
Inspect cable connections	Annually
Inspect overlay for wear and water seal	Annually

DO NOT:

• ❌ Use abrasive cleaners or scouring pads

🤔 Frequently Asked Questions

Q: Are the overlays included? A: Yes — TWO overlays are included with this 0200-007194 listing. The bundled kit includes:

• Overlay 9916-100130 — 8-button M-CLASS layout: Pump 1 / Pump 2 / Blower / Light / Power / Filter / Temp+ / Temp-
• Overlay 9916-100331 — 7-button S-CLASS layout: Pump 1 / Pump 2 / Light / Blower / Economy Mode / Temp+ / Temp-

Apply the overlay matching your spa pack architecture (M-CLASS vs S-CLASS). Save the unused overlay in case you ever convert systems or need a spare.

Q: What is “M-CLASS” vs “S-CLASS”? A: Both M-CLASS and S-CLASS are older Gecko Alliance spa pack control architectures — predecessors to the modern Gecko in.Link Y-Series and X-Series ecosystems. They were widely used on premium spas in the late 1990s through the 2000s. The TSC-8 is unique among Gecko M-CLASS keypads because it ships with overlays for BOTH architectures, giving service shops and owners flexibility:

• M-CLASS — Primary M-CLASS spa pack family (uses 8-button overlay 9916-100130)
• S-CLASS — S-CLASS spa pack systems with LCD option (uses 7-button overlay 9916-100331)

If you’re unsure which architecture your spa has, check the spa pack inside the equipment cabinet for an M-Class or S-Class label, or contact Parts4Tubs with your spa pack model number.

Q: How is the TSC-8 different from the TSC-4? A: Both are 8-button M-CLASS keypads with similar 7″ × 3-1/4″ form factors but with different button layouts:

• TSC-8 (this listing — 0200-007194) — Pump 1 / Pump 2 / Blower / Light / Power / Filter / Temp+ / Temp- (M-CLASS 8-button)
• TSC-4 (0200-007119) — Up / Pump 1 / Pump 2 / Prog / Down / Blower / Light / Mode (M-CLASS 8-button)

Choose the TSC-8 if direct access to filtration programming and system power state is important to you. Choose the TSC-4 if mode-cycling (Standard/Economy/Sleep) and programming menus are more important. Both share the same 8-pin JST connector and M-CLASS compatibility.

Q: What is the TSC-8-10K? A: The TSC-8-10K (0201-007153) is the 10-button 3-pump variant of the TSC-8 family — designed for premium spas with 3 jet pumps. It uses overlay 9916-100723. If you have a 3-pump M-CLASS spa, choose the TSC-8-10K instead of this 8-button TSC-8.

Q: My old keypad part says 0200-007072, 0200-007113, 301763, BDLTSC8GE1, BDLTSC8GE2, or TSC-14 — is this the same? A: Yes — all of these are alternate references for the TSC-8 family that the 0200-007194 (this listing) replaces:

• 0200-007072 = older Gecko reference
• 0200-007113 = internal keypad-only SKU (bundled here with overlays)
• 301763 = alternate distributor reference
• BDLTSC8GE1, BDLTSC8GE2, BDLTS8CGE1 = former Gecko bundle references
• TSC-14 = older Gecko keypad — directly replaced by TSC-8

Q: My Coleman / Maax Spa has cross-reference 104522 — is this the right replacement? A: Yes — the TSC-8 (0200-007194) is the direct factory equivalent for the Coleman / Maax Spas 104522 topside cross-reference. Coleman / Maax Spa owners can identify their existing keypad by this brand-specific part number.

Q: My Hawkeye Spa has the proprietary K-8 (3-00-7052) — can this replace it? A: Yes — the TSC-8 (0200-007194) can be used as a replacement option for the proprietary Hawkeye Spas 3-00-7052 K-8 topside control. Hawkeye Spa owners with the original K-8 topside can use this Gecko-branded equivalent as an aftermarket replacement.

Q: What is “TSC-14” and is the TSC-8 the right replacement? A: TSC-14 is an older Gecko M-CLASS keypad that was directly replaced by the TSC-8. If your existing keypad is a TSC-14, the TSC-8 (this listing) is the modern current-production replacement.

Q: What are the compatible circuit boards? A: The TSC-8 works with these Gecko M-CLASS spa pack circuit boards:

• 0201-300045 (M-CLASS standard)
• 0201-300014 (M-CLASS variant)
• 59-337-1250 (M-CLASS variant cross-reference)
• 59-337-1260 (M-CLASS variant cross-reference)

If your spa pack has one of these circuit board numbers stamped on it, the TSC-8 is compatible.

Q: What is the Filter button for? A: The TSC-8’s dedicated Filter button provides direct access to filtration cycle programming — set daily filter cycle start time, configure cycle duration, trigger manual on-demand filter cycles, and adjust filtration parameters. This is more accessible than keypads requiring multi-button programming sequences for filter configuration.

Q: What is the Power button for? A: The dedicated Power button provides direct control of the spa pack’s main power state — useful for putting the spa into standby mode, switching between active and passive states, and quick power-cycling for resetting (without going to the GFCI breaker).

Q: How is the TSC-8 different from modern Gecko in.Link keypads? A: They’re for completely different Gecko ecosystems:

• TSC-8 (this listing) — Gecko M-CLASS / S-CLASS architecture, 8-pin JST connector, older ecosystem
• Modern in.Link keypads (in.k200, in.k300, in.k450, in.k500, in.k600, in.k800, in.k1000) — Gecko Y-Series / X-Series ecosystems, in.Link connector, modern features

The two ecosystems are NOT interchangeable. Verify your spa’s spa pack architecture and connector type before ordering.

Q: Will this work with my Balboa spa pack? A: No — the TSC-8 is strictly for Gecko M-CLASS or S-CLASS spa packs. Balboa systems use different connectors (RJ45 for VS/GS, Molex for BP/EL/GL) and different communication protocols.

Q: Can I install this myself? A: Yes — basic DIY installation is straightforward:

1. The 8-pin JST connector only fits one way
2. Two overlays are included; choose the right one for your system (M-CLASS or S-CLASS)
3. Step-by-step instructions are documented in the Gecko M-CLASS / S-CLASS documentation

The hardest part is safely shutting off power at the GFCI breaker.

Q: Will this work with my 120V or 240V spa? A: Yes — the keypad runs on low-voltage signal from the spa pack, so it works regardless of whether your Gecko M-CLASS / S-CLASS spa pack is wired for 115V or 230V service.

Q: What warranty is included? A: This part is covered by the Gecko Alliance manufacturer warranty. Topside controls are not returnable once opened or installed.

Q: Do you ship across the US? A: Yes — Parts4Tubs ships to all 50 states with fast US delivery.

What is a Hot Tub Keypad Overlay?

A hot tub keypad overlay, also known as a spa control panel overlay, is a protective and decorative component used in hot tubs and spas. It typically consists of a thin, clear or colored piece of material, often made of durable plastic or silicone, that is designed to cover and protect the control panel or keypad of the hot tub.

Here's what a hot tub keypad overlay does:

1. Protection: The overlay acts as a protective barrier for the underlying control panel or keypad. It shields the sensitive electronics and buttons from exposure to water, chemicals, UV rays, and physical damage, such as scratches or abrasions. This helps extend the lifespan of the control panel.

2. Enhancement: Many overlays are designed with labels, graphics, and button outlines that enhance the appearance of the control panel. They often include icons or text that provide clear instructions for operating the hot tub, making it user-friendly, especially for those who may not be familiar with the hot tub's functions.

3. Customization: Hot tub keypad overlays can be customized to match the branding or style of the hot tub manufacturer. They may feature the manufacturer's logo, model name, or specific design elements. Some hot tub owners choose to customize overlays to add a personal touch to their spa.

4. Ease of Cleaning: The overlay is easier to clean and maintain than the underlying control panel. Spills, dirt, or chemical residues that come into contact with the overlay can be wiped away without affecting the control panel's functionality.

5. Replacement: Over time, keypad overlays may wear out or become damaged due to exposure to harsh spa conditions. Fortunately, they are relatively easy and cost-effective to replace when needed, allowing you to refresh the appearance of your hot tub's control panel.

When replacing a hot tub keypad overlay, it's essential to choose one that is compatible with your hot tub's make and model to ensure that the button layout and functions match the original control panel. This compatibility ensures that the overlay fits correctly and accurately represents the hot tub's settings.

In summary, a hot tub keypad overlay serves as a protective, decorative, and informative layer for the control panel, enhancing the user experience and prolonging the life of the hot tub's control system.

How do you replace a hot tub keypad overlay?

Replacing a hot tub keypad overlay is generally a straightforward process that can be done with some basic tools and careful attention. Here's a step-by-step guide on how to replace a hot tub keypad overlay:

Tools and Materials Needed:

• New keypad overlay (ensure it's compatible with your hot tub model)
• Screwdriver (usually a Phillips-head)
• Mild cleaner or rubbing alcohol
• Soft cloth or paper towels

Step-by-Step Instructions:

1. Turn Off Power: Start by turning off the power to your hot tub. This is essential for safety reasons.

2. Access the Control Panel: Depending on your hot tub's design, you may need to remove a cover or panel to access the control panel. Use a screwdriver to remove any screws or fasteners holding the cover in place.

3. Remove the Old Overlay: Carefully peel off the old keypad overlay. Begin at one corner and gently lift it away from the control panel. Take your time and be cautious not to damage the control panel or its components.

4. Clean the Control Panel: After removing the old overlay, use a soft cloth or paper towel and a mild cleaner or rubbing alcohol to clean the control panel's surface. This step ensures that the new overlay adheres properly and looks clean.

5. Prepare the New Overlay: Ensure that the new hot tub keypad overlay is clean and free of any dust or debris. If the new overlay has an adhesive backing, remove the protective film to expose the adhesive.

6. Align and Apply the New Overlay: Carefully align the new overlay with the control panel. Make sure it matches the button layout and design of the control panel. Begin by aligning one corner and gradually press the overlay onto the control panel's surface, working your way across. Smooth out the overlay to prevent air bubbles or wrinkles.

7. Secure the Control Panel Cover: If you had to remove a cover or panel to access the control panel, reattach it using the screws or fasteners you removed earlier.

8. Turn On Power: Once the new overlay is securely in place, and the control panel cover is reattached, turn the power back on at the main circuit breaker.

9. Test the Keypad: Test the keypad buttons to ensure they function correctly. Press each button to verify that it corresponds to the correct function on the hot tub.

10. Final Cleaning: After installation and testing, wipe down the new overlay with a clean, dry cloth to remove any fingerprints or residue.

You've now successfully replaced your hot tub's keypad overlay. Make sure to use a compatible overlay, and exercise caution during the replacement process to avoid damaging the control panel.
