FAQs
Do I need a gateway for remote control?
Yes, a separate compatible gateway is required to enable control of the underfloor heating system via the smartphone app.
How often do I need to replace the batteries?
Battery life typically lasts for a significant period, but it is recommended to replace them annually or when the low battery indicator appears on the thermostat display.
Can this thermostat be used with other heating systems?
This thermostat is specifically designed for use with underfloor heating systems and requires a compatible John Guest RF wiring center.
What is the 'Adaptive function'?
The Adaptive function learns how long it takes to heat your room and starts the heating system in advance to ensure it reaches your desired temperature exactly when you want it, preventing temperature spikes.
How does the 'Open Window' function work?
It detects a sudden drop in room temperature, characteristic of an open window, and temporarily turns off the heating to save energy. It will resume normal operation after a set period or when the temperature stabilizes.
What temperature range can I set for Freeze Protection?
The Freeze Protection function is adjustable between 5°C and 17°C, suitable for preventing pipes from freezing in unused areas during colder months.
Is professional installation required?
While the battery operation and RF signalling simplify installation compared to wired thermostats, professional installation of the RF wiring center is recommended for optimal performance and safety.
Troubleshooting
Thermostat not communicating with wiring center
Check battery levels in the thermostat. Ensure the thermostat is within range of the wiring center. Try re-pairing the devices following the manual's instructions.
Incorrect temperature displayed
Ensure the thermostat is not placed near a heat source or in direct sunlight. Verify that the ambient sensor is clear. If using an external probe, check its connection and condition.
Heating not activating as scheduled
Verify the program schedule is correctly set for the current day and time. Check if the 'Open Window' or 'Freeze Protection' functions are active. Ensure the RF wiring center is powered and functional.
App control not working
Confirm the gateway is powered and connected to the network. Ensure your smartphone has a stable internet connection. Check that the thermostat is correctly paired with the gateway via the app.
Boiler firing up unnecessarily
Check the 'Open Window' function sensitivity. Ensure no drafts are causing false triggers. Review the thermostat's programming for any conflicting settings.
