Operation

Initial Start-Up & Standby Mode

• Once the unit has been powered on, the panel will enter an initialization state.
• Once this has been completed, the panel will enter the normal control interface.
• After 30 seconds of inactivity, the display will turn blank. This is the standby mode. Press any button to wake the display up.

Changing Operation Mode

Press the rotary knob to enter the operation select mode. Turn the knob to the left or the right and press it to select the desired mode. When the heater is running, both the variable output, and thermostatic modes can be switched between, but not the fan only mode.

Operating Modes

Variable Output Mode
In variable output mode, once turned on the heater will continue to run until it is manually turned off again. Whilst turned on, the rotary knob is used to select the power output (fan speed) of the heater. The higher the fan speed, the greater the volume of hot air will be pushed into the heating space.

1. Once you’ve selected the variable output mode, hold the rotary knob for three seconds.
2. The LED indicators will turn green, and the display will change from ‘ON’ to ‘OFF’.
3. Use the rotary knob to change the power output between P1 (lowest) to P7 (highest).
4. Press and hold the rotary knob to switch the heater off. The LED indicators will turn red, and the heater will then run its cooldown cycle for several minutes, before switching off completely.

Thermostatic Mode
In thermostatic mode, the heater will run until it has reached the set temperature and (version dependent) will either switch off completely or continue to run the fan until the temperature has dropped significantly the heater will then relight and start again. The unit will continue to cycle until the controller is switched off completely. Temperature will vary depending on where the temperature probe is installed, and how much ambient air flow it has.

1. Once you’ve selected the thermostatic mode, hold the rotary knob for three seconds.
2. The LED indicators will turn green, and the display will change from ‘ON’ to ‘OFF’.
3. Use the rotary knob to change the temperature between 5°C (lowest) to 35°C (highest).
4. Press and hold the rotary knob to switch the heater off. The LED indicators will turn red, and the heater will then run its cooldown cycle for several minutes, before switching off completely.

Fan Only Mode
In fan-only mode, once turned on the heater will only run the fresh air fan until it is manually turned off again. Whilst turned on, the rotary knob is used to select the fan speed. The higher the fan speed, the greater the volume of air will be pushed into the heating space.

1. Once you’ve selected the fan-only mode, hold the rotary knob for three seconds.
2. The LED indicators will turn green, and the display will change from ‘ON’ to ‘OFF’.
3. Use the rotary knob to change the power output between P1 (lowest) to P7 (highest).
4. Press and hold the rotary knob to switch the heater off.
