Model DXLAT150Ti is controlled by a Digital Timer – see ‘Digital
Timer Operation’

The heat output is controlled by the thermostat - see ‘Thermostat’

Please note – the element has been coated with a protective film
which will burn off during the first few minutes of use and may
cause a small amount of fuming. This is quite normal – the fumes
are non-toxic and will quickly disappear. We recommend that you
open a window to ventilate the room when using the heater for
the first time.

Controls

Thermostat

- see Fig. 3

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, turn the thermostat knob
clockwise until the desired temperature is reached. Alternatively
to heat a cold room quickly, turn the thermostat knob up fully.

When the room has reached the desired temperature, turn the
thermostat knob anti-clockwise until the thermostat just clicks
off.

The heater will now automatically operate at this 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.
