♨️ Tecmark Digital Command Center Topside Control Panel (4-Button, 230V, Without Overlay) — Genuine Tecmark Replacement for Pneumatic Spa Control Systems
Genuine Tecmark Corporation pneumatic replacement panel — durable air-switch control for electromechanical spa packs.
📋 Product Overview
The Tecmark Digital Command Center is a 4-button, 230V topside control panel built for spas and hot tubs that use pneumatic (air-button) control systems — the long-established analog control architecture used in EasyPak and many older electromechanical spa packs. Unlike modern low-voltage electronic topsides, the Command Center is a complete spa-side control package that handles line-voltage switching directly: each press of a tactile air button sends a pulse of compressed air through small-diameter tubing to the spa pack, where the pulse is converted into an electrical signal to switch pumps, blowers, lights, and other accessories.
This listing is for the panel without overlay — ideal for spa technicians and OEM hot tub builders who plan to apply a custom Command Center overlay sticker (Tecmark 30191BM or similar) separately. The unit includes the integrated 4-button Command Center body with digital temperature readout, equipment status indicating lights, remote sensing thermostat with capillary and 5/16″ bulb assembly, and the factory 10-foot cord with the 5-pin large molded connector.
The 4-button Command Center is also widely installed as a universal replacement — the extra buttons can simply remain unconnected if your spa only needs 2 or 3 active controls. This is the 230V (240V) version of the panel, designed for spas wired to 230V/240V service. A 120V/115V version (CC4D-120) is also available for North American single-phase 120V installations. Genuine Tecmark Corporation OEM product, used in spas requiring direct line-voltage pneumatic control.

Voltage Variants:
| Variant | Tecmark Part | Notes |
|---|---|---|
| 230V (240V) | CC4D-240-10I-00 | This listing |
| 120V (115V) | CC4D-120-10I-00 | For 120V single-phase service — different SKU, ordered separately |
⚠️ CRITICAL: This is the 230V (240V) version. Do NOT install on a 120V spa — voltage mismatch will damage the unit and may create an electrical hazard. If your spa is wired for 120V, you need the CC4D-120 variant instead.
NOT Compatible With:
- ❌ Modern low-voltage electronic topside spa packs (Balboa BP, Gecko in.YE / in.YJ, HydroQuip CS series, etc.)
- ❌ Any spa pack that uses a 4-pin Molex or 8-pin Molex topside connector — those are electronic systems
- ❌ Spas wired for 120V service (use CC4D-120 instead)
- ❌ Touchscreen or LCD-only spa packs
How to Verify Compatibility:
📍 Check your existing topside — pneumatic Command Center panels have soft, mushroom-shaped rubber air buttons that depress with a “click” feel and are connected to small clear plastic tubing 📍 Look for a 5-pin large molded electrical connector on the existing topside cord — Command Centers do not use Molex connectors 📍 Check your spa pack — pneumatic systems have small air tube fittings on the side or top of the spa pack housing where the buttons connect 📍 Confirm spa voltage — 230V or 240V wiring (typically 4-wire service in North America, or single-phase 240V in EU/UK 50Hz markets) 📍 Verify the existing cutout is approximately 5-5/8″ × 2-1/2″ 📍 Contact Parts4Tubs with your spa pack model number if you’re unsure
⚠️ Important: The Tecmark Command Center is fundamentally different from modern electronic topsides like the Balboa TP series. If your spa uses a Molex connector for the topside cable, this is NOT the right replacement — that’s an electronic spa pack, not a pneumatic one.
🔘 Button Functions & Display
The Command Center has 4 pneumatic buttons. Functions are determined by which devices your spa pack is wired to switch when each button is pressed — this varies by spa configuration. Common assignments include:
| Button | Typical Function |
|---|---|
| Button 1 | Pump 1 (Jets) on/off and speed cycle |
| Button 2 | Pump 2 or Air Blower on/off |
| Button 3 | Light on/off |
| Button 4 | Auxiliary device or unused (can remain blocked) |
📌 Each button is a “transmitter” — pressing it sends a pulse of compressed air through 1/8″ or 1/16″ tubing to the corresponding sequencer/relay in the spa pack, which switches the load. Button assignments are determined by the spa pack wiring, not by the topside itself.
Display & Temperature Control:
- 🖥️ Digital temperature readout — Shows current water temperature (and may show set point depending on spa pack)
- 💡 Equipment status indicator lights — Show pump, heater, and accessory active states
- 🌡️ Remote sensing thermostat — The 48″ capillary bulb senses water temperature at the heater; the topside thermostat dial sets the desired temperature
- 🌡️ 5/16″ temp sensor bulb — Standard Tecmark thermostat bulb size for this Command Center series
📌 Unlike modern electronic topsides where the spa pack handles all temperature logic, the Command Center’s thermostat is integral to the topside itself. The capillary tube runs from the topside to the heater area where the bulb senses water temperature directly.
🛠️ Installation Guide
Before Installation:
- ⚠️ Disconnect power at the GFCI breaker before any work
- ⚠️ Confirm your spa pack is a pneumatic (air-button) system — Command Centers are NOT compatible with electronic Molex-connector spa packs
- ⚠️ Confirm your spa is wired for 230V/240V (use CC4D-120 for 120V spas)
- ⚠️ Verify the 10-foot cable will reach from the topside to the spa pack
- ⚠️ Verify the 48″ capillary will reach from the topside cutout to the heater housing
- ⚠️ Have your replacement overlay ready (or prepare a new overlay sticker)
Installation Steps:
- Turn off power at the GFCI / disconnect serving the spa
- Open the spa cabinet and locate the topside cord and air tubing on the spa pack
- Disconnect the 5-pin connector from the spa pack
- Disconnect the air tubes from the spa pack — note which tube goes to which button position
- Carefully extract the capillary bulb from the heater housing (note its routing for reinstallation)
- Remove the old topside from the spa shell cutout
- Verify the cutout matches approximately 5-5/8″ × 2-1/2″ (use the new panel as a template if needed)
- Apply the new overlay sticker to the new panel (or transfer the existing overlay)
- Route the new cord, capillary, and air tubes through the cabinet to the spa pack
- Reinstall the capillary bulb in the heater housing — match its original routing
- Reconnect the air tubes to the same button positions on the spa pack as the originals
- Plug the new 5-pin connector into the spa pack
- Mount the new topside in the spa shell cutout — peel the protective backing off the factory foam gasket and press firmly into place; secure with the supplied stainless mounting screws if applicable
- Restore power at the breaker
- Test all functions — temperature setting, each air button, status lights
Mounting:
| Requirement | Specification |
|---|---|
| Panel size | 6-1/2″ × 3-1/4″ (rectangular) |
| Cutout size | 5-5/8″ × 2-1/2″ |
| Mounting type | Self-adhesive foam gasket (factory installed) + optional mounting screws |
| Adapter plate | Available — Tecmark Command Center adapter plate (fits 3 & 4-button) |
⚠️ Professional installation by a licensed electrician is strongly recommended for line-voltage pneumatic spa controls. All work must comply with the National Electrical Code (NEC) and local codes. Unlike low-voltage electronic topsides, Command Centers carry 230V circuits — the electrical risk is significantly higher.
⚡ Wiring & Connection
Connector Information:
| Specification | Detail |
|---|---|
| Connector Type | 5-Pin Large Molded (proprietary Tecmark Command Center connector) |
| Cord Length | 10 ft standard |
| Voltage | 230V (240V) — line voltage |
Air Tubing:
| Specification | Detail |
|---|---|
| Air tube ID accepted | 1/8″ or 1/16″ inner diameter |
| Number of air tubes | 4 (one per button) |
| Replacement | Standard pneumatic tubing available from spa parts suppliers |
Connection Location:
The 5-pin connector plugs into the dedicated Command Center port on the spa pack.
The air tubes connect to the corresponding button-input ports on the spa pack
sequencer / relay board.
The capillary bulb installs in the heater housing or sensor pocket.
⚠️ Air tubes must be cut to length and pushed firmly onto the barbed fittings on both ends. A loose air tube means a non-functioning button — and a kinked tube can prevent button operation entirely.
🔍 Troubleshooting
Common Issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Button doesn’t activate equipment | Air leak, kinked tube, or failed bellows | Inspect tubing for kinks; replace bellows if soft/cracked |
| Multiple buttons activate same function | Crossed air tubes | Verify each tube goes to correct sequencer port |
| No power / blank display | No supply power or loose 5-pin connector | Verify breaker on; reseat the 5-pin plug at the spa pack |
| Heater won’t shut off | Capillary bulb dislodged or thermostat fault | Check that bulb is properly seated in the heater pocket |
| Inaccurate temperature reading | Capillary bulb not sensing water properly | Reseat bulb; verify thermal contact |
| Status lights don’t illuminate | Wiring fault or LED failure | Check 5-pin connector; replacement may be needed |
| Air buttons feel mushy or stuck | Worn or torn bellows | Replace with Tecmark bellows kit |
| Wrong button functions | Air tubes connected to wrong ports | Trace each tube to the spa pack and reassign |
Air System Maintenance:
Pneumatic systems rely on airtight tubing and intact bellows.
A small air leak in any tube causes that button to require harder presses
or to stop working entirely.
Bellows can be replaced individually using the Tecmark bellows kit.
🔧 Maintenance & Care
Routine Care:
| Task | Frequency |
|---|---|
| Wipe panel face with damp cloth | Weekly |
| Test each button for proper response | Monthly |
| Inspect capillary tube and bulb | Annually |
| Inspect air tubing for kinks or cracks | Annually |
| Inspect overlay for wear and water seal | Annually |
DO NOT:
- ❌ Use abrasive cleaners or scouring pads
- ❌ Submerge the panel in water or chemicals
- ❌ Use solvent-based cleaners (acetone, lacquer thinner, etc.)
- ❌ Press buttons with sharp objects (pens, keys, fingernails) — damages bellows
- ❌ Crimp, pinch, or kink the air tubing during installation
Bellows Replacement:
If individual air buttons feel mushy, hard to press, or stop activating their function, the underlying bellows (rubber air-pressure cup) can be replaced with the Tecmark bellows kit — fits 2-, 3-, and 4-button Command Center panels. This is often a less expensive repair than replacing the entire topside.

🤔 Frequently Asked Questions
Q: Is the overlay included? A: No — this listing is for the topside panel only, without the overlay sticker. You can either transfer the overlay from your existing panel or purchase a replacement overlay separately. Tecmark Command Center 4-button overlays are widely available; contact Parts4Tubs for the matching part number.
Q: What’s the difference between this and the Balboa TP-series topsides? A: They’re entirely different control architectures. The Tecmark Command Center is a pneumatic (air-button) line-voltage panel — buttons send pulses of compressed air to the spa pack via small tubing, and the panel handles 230V directly. The Balboa TP-series (TP500S, TP600, TP700, etc.) are electronic low-voltage panels that use a Molex connector and digital signaling. They’re not interchangeable — your spa pack must be designed for one or the other.
Q: How do I know if my spa uses pneumatic controls? A: Look at your existing topside. Pneumatic systems have soft, mushroom-shaped rubber air buttons that you press down — they typically have a small clicking feel as the bellows compresses. The cord coming out of the topside is thicker and includes both the electrical wiring AND multiple thin clear/black plastic air tubes that route to the spa pack. Modern electronic systems have small flat plastic buttons and just a single cable with a Molex connector.
Q: Is this 120V or 230V? A: This is the 230V (240V) version. If your spa is wired for 120V/115V single-phase service, you need the CC4D-120 variant instead — same panel, different internal voltage rating.
Q: How do I tell what voltage my spa is wired for? A: Check your spa’s electrical service label or breaker. North American spas wired through a single 20A or 30A breaker on a single 120V circuit are 120V. Spas wired through a 240V dedicated breaker (typically 40A, 50A, or 60A double-pole) are 240V/230V. If you’re not sure, consult an electrician.
Q: What’s the cord length? A: The cord is 10 feet long with a 5-pin large molded connector. The capillary (for the temperature bulb) is 48 inches long.
Q: Does this work with EasyPak spa packs? A: Yes — the Tecmark Command Center is widely used with EasyPak and other electromechanical spa control systems that use pneumatic topside switching.
Q: Why does the panel have 4 buttons when my spa only has 2 or 3 active functions? A: Tecmark designed the 4-button Command Center as a universal panel — even if your spa pack only switches 2 or 3 functions, the extra unused button positions can remain unconnected (or covered by your overlay). This lets builders and repair shops stock one universal SKU instead of separate 2-button, 3-button, and 4-button panels. The 3-button version of this Command Center has been discontinued by Tecmark in favor of the 4-button universal layout.
Q: My buttons feel mushy and don’t activate the equipment. Do I need a new panel? A: Not necessarily — try the Tecmark bellows replacement kit first. The bellows (rubber air cups under the buttons) are a common wear item, and replacing them often restores full function without replacing the entire panel. If the digital display or thermostat has also failed, then a full panel replacement is the right move.
Q: What if my old cutout doesn’t match the 5-5/8″ × 2-1/2″ hole? A: A Tecmark Command Center adapter plate is available that fits the 3-button and 4-button Command Center panels and covers larger or differently-shaped older cutouts. Contact Parts4Tubs for adapter plate options.
Q: Can I install this myself? A: Tecmark Command Center installation is moderately involved because it includes electrical (230V), pneumatic (air tubing), and mechanical (capillary bulb) connections. If you’re comfortable safely shutting off power at the GFCI breaker and have experience working with line-voltage circuits, DIY installation is possible. For 230V installations, a licensed electrician is strongly recommended for NEC and local code compliance.
Q: Does the topside come with the foam mounting gasket? A: Yes — the panel ships with a factory-installed double-sided foam mounting gasket on the back. Just peel the protective backing and press firmly into the cutout for a watertight seal.
Q: Do you ship across the US? A: Yes — Parts4Tubs ships to all 50 states with fast US delivery.
