- Preparation: Ensure the radiator valve is clean and free from debris. If replacing an old head, remove it carefully.
- Mounting: Align the thermostatic head with the M30 threaded connection on your radiator valve.
- Tightening: Screw the head onto the valve by hand until it is firmly seated. No tools are typically required for this step. Do not overtighten.
- Temperature Limitation (Optional): The head features a limitation ring and captive stop system. Refer to the markings on the head to set minimum and maximum temperature limits if desired. This can be done without tools.
Once installed, the heating system can be repressurized if necessary.
Operating Instructions
The COMAP Thermostatic Head allows for manual temperature control within the room.
- Adjusting Temperature: Rotate the ring on the thermostatic head to select your desired temperature setting. The head typically has numerical markings (e.g., 1 to 5 or specific temperature indicators) corresponding to different heat levels.
- Setting Levels:
- The snowflake symbol (*) usually indicates a frost protection setting (around 6-7°C).
- Lower numbers (e.g., 1, 2) correspond to lower temperatures.
- Higher numbers (e.g., 3, 4, 5) correspond to higher temperatures.
- Automatic Regulation: The liquid sensor inside the head will automatically open or close the valve to maintain the selected room temperature.
For optimal energy efficiency, avoid setting the head to maximum when a lower comfortable temperature is sufficient.
Maintenance
The COMAP Thermostatic Head requires minimal maintenance to ensure long-term performance.
- Cleaning: Wipe the head periodically with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Dust Removal: Ensure the stylized openings are free from dust or obstructions, as these are crucial for the sensor's accurate temperature detection.
- Function Check: Occasionally rotate the head through its full range of settings to ensure the valve pin moves freely. If the pin appears stuck, gently press it a few times.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator not heating up. | Thermostatic head set too low, valve pin stuck, air in radiator, central heating system off. | Increase setting on head. Gently press valve pin to free it. Bleed the radiator. Check central heating system. |
| Room is too hot despite low setting. | Thermostatic head faulty, external heat source influencing sensor, valve pin stuck open. | Ensure no direct sunlight or other heat sources are affecting the head. Check valve pin. Consider replacing the head if problem persists. |
| Head is loose on the valve. | Not tightened sufficiently during installation. | Gently re-tighten the head by hand onto the valve. |
If troubleshooting steps do not resolve the issue, please contact a qualified technician or COMAP support.
