Installation
This product is suitable for installation in a standard 86mm rectangle recessed box or a 60mm European recessed box. Follow these steps carefully:
- Turn off the main power: Before beginning any electrical work, ensure the main power supply to the heating system and the installation area is completely disconnected at the circuit breaker.
- Separate the installation panel: Gently rotate the display screen frame to separate it from the main installation panel. This will expose the mounting holes and wiring terminals.
- Connect wiring: Refer to the wiring diagram below. Connect the live (L) and neutral (N) wires from your AC95-240V power supply to the corresponding terminals. Connect the boiler heating system wires to the appropriate output terminals (e.g., Dry Contact 1 and 2). If an external NTC sensor is used, connect it to the NTC terminals.

- Attach the display unit: Carefully reattach the display screen frame to the installed panel, ensuring it clicks securely into place.
- Restore power: Once installation is complete and all connections are verified, restore power at the circuit breaker. The thermostat display should illuminate.
Operation
The thermostat features an intuitive LED display and capacitive touch buttons for easy control of your heating system.

Programmable Schedule (5+1+1):
The thermostat supports a 5+1+1 programmable schedule, allowing you to set different temperature profiles for weekdays (5 days), Saturday (1 day), and Sunday (1 day), with up to 6 time periods per day. This feature helps in energy saving by adjusting heating based on your daily routine.
- Enter Program Mode: Press and hold the program icon (often represented by a calendar or clock) to enter the programming settings.
- Set Time Periods: Use the up/down arrows to adjust the start time and desired temperature for each of the 6 periods.
- Select Day Group: Navigate between weekday, Saturday, and Sunday settings.
- Save Settings: Confirm your settings, usually by pressing the program icon again or waiting for a timeout.
Refer to the on-screen prompts and icons for specific navigation within the programming menu.
Maintenance
The Pomya Digital Thermostat requires minimal maintenance to ensure optimal performance and longevity.
- Cleaning: Periodically wipe the display and exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the thermostat.
- Avoid Obstructions: Ensure that no furniture, curtains, or other objects block the thermostat, as this can affect its ability to accurately sense room temperature.
- Power Cycling: If the thermostat becomes unresponsive, try turning off the main power at the circuit breaker for a few minutes, then restore power.
Troubleshooting
If you encounter issues with your thermostat, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat display is blank | No power, loose wiring, circuit breaker tripped. | Check circuit breaker. Verify wiring connections. Ensure main power is on. |
| Heating system not responding | Incorrect wiring, thermostat in wrong mode, temperature setting too low. | Verify wiring. Switch to Heating or Manual mode. Increase desired temperature. |
| Inaccurate temperature reading | Thermostat location, blocked sensor. | Ensure thermostat is not in direct sunlight or near heat sources/drafts. Clear any obstructions. |
| Programmable schedule not working | Thermostat not in program mode, incorrect schedule settings. | Ensure thermostat is set to Program mode. Recheck schedule times and temperatures. |
| Touch buttons unresponsive | Temporary software glitch, dirty screen. | Power cycle the thermostat. Clean the screen with a soft, dry cloth. |
