Your thermostat sends instructions to your air source heat pump, telling it how much heat your home needs. It doesn’t deliver instant heat like a gas boiler - your heat pump increases warmth gradually for better efficiency.
How to use your thermostat
- press the three‑line button in the middle of the device.
- use the scroll bar on the right to adjust the temperature.
- press the three‑line button again to confirm your change.
- you can also set schedules for heating and hot water.
- if the room is already warmer than the desired temperature, the heating will not turn on.
Useful information
- your heating should be left ON at a range of 18–24°C
- the recommended setting is 21°C, which supports efficient running
- keeping your home at a steady temperature works best — heat pumps don’t provide rapid boosts like gas boilers
- turning your heating off completely makes it slower and harder to warm up again
- in summer you can turn the heating right down, but keep hot water on
- the thermostat tells the heat pump how much heat is needed
- small temperature changes respond more effectively
- large jumps (e.g., 18°C → 24°C) take much longer — up to 24 hours
- once adjusted, the system maintains a consistent temperature automatically
- press the three‑line menu button to access help topics
- faults will appear as messages on your control panel
- when reporting an issue, always provide the fault message shown on screen
- located on an outside wall.
- if it senses temperatures around 30°C or above, heating will not turn on.
- this is normal for heat pump systems.
- do not open or attempt to service the thermostat.
- follow the user manual for advanced settings if needed.
