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.
Switches (selected models)
Some models are supplied with selector switches . There are two switch
types, one is an on/off switch and the other is a heat selection switch.
Depending on model either one or both switch may be included. The switch
operation is as follows.
On/ Off: O - Off
I - On
Heat selection I - Low heat
II - High heat

I position there is a 2kw output from the product. When O/I switch is
in position I and the I/II switch is in the II position there is a 3kW output
from the product. The indicator neon is always on when the product is
connected to the mains supply.
403TSTi Operation
This model contains a heat selection switch and an electro-mechanical
timer and operates as follows.
When the timer is switched to I and the I/II switch is in position I there is
a 2kW output from the product. When the timer is switched to I and the
I/II switch is in position II there is a 3kW output from the product. When
the timer is in the ‘ ’ position and the I/II switch is in position I there is a
2kW output from the product when the timer is set on. When the timer is
in the ‘ ’ position and the I/II switch is in position II there is a 3kW output
from the product when the timer is set on. The indicator neon is always
on when the product is connected to the mains supply.
