Set the temperature 

The temperature shown on the display is the room temperature 
setpoint. This is the temperature that the heater will maintain 
during the 

Comfort On

’ 

periods. If the room temperature is 

above this temperature then the fan will not operate.
The heater leaves the factory with this temperature set at 21°C 
which represents a typical, comfortable room temperature. 
If you require a different room temperature use the 

Up and Down

 

buttons until the display shows the 

temperature you require.

YOU DO NOT NEED TO TURN THE TEMPERATURE DOWN OVERNIGHT.

How does the heater control work? 

The heater control allows you to choose when you want the heating to be on, and at what 
temperature. To deliver the required heat a low noise fan pushes stored heat from the core into the 
room. 

The periods during which the heater is providing heat are called 

Comfort On

’ 

(shown at the bottom 

of the screen). Outside of these periods the heater will not deliver heat and these periods are called

 

Comfort Off 

’. 

During the

 ‘

Comfort On

’ 

periods the fan will run to maintain the temperature on the 

screen. During the 

Comfort Off 

’ 

periods it will not.

Note: there is a delay of up to a minute on the fan operation when switching to ‘Comfort 
On’ or ‘Comfort off ’. This is normal and does not represent a fault.
