Thermostat (all models)
The thermostat controls the heat output according to the room temperature.
This ensures that the heater will not produce heat unnecessarily when the
room is warm.
To set the temperature you require, gradually turn the thermostat knob
clockwise until the desired temperature is reached. Allow some time
between increments for the room temperature to stabilise.
Alternatively to heat a cold room quickly, turn the thermostat knob to the
Max position. When the room has reached the desired temperature, turn
the thermostat knob anti-clockwise until the thermostat clicks off. The heater
will then automatically maintain this room temperature.
The thermostat also has a frost protection setting marked ‘ ’. This setting is
useful in areas such as garages to prevent frost damage. If the thermostat is
set to its minimum setting ‘ ’, the heater will cycle ON and OFF to maintain
a temperature of approximately 5°C to help protect against frosty conditions.

types, one is an on/off switch and the other is a heat selection switch.
