Setting your room temperature
Your current room temperature is shown in the display.
To set the temperature you want, just turn the dial
right to increase and left to decrease. Each 'click'
as the dial turns represents a 0.5º change.
After five seconds the current room temperature will be
displayed once again. The thermostat will then try to
maintain your set temperature as accurately as possible.
You can check your set temperature by turning the dial one 'click'
to the left or right. The set temperature will flash up for a few
seconds, before returning to display the room temperature again.
Night-time temperature reduction
Overnight, or if you are out, it is best to set the thermostat to
a lower temperature, as it will save you energy. In general a
reduction of 5°C is recommended, but this will depend on your
heating system and the amount of insulation in your home.
Replacing the batteries
Your batteries should be replaced
when the symbol is displayed.
To do this, separate the thermostat
from the wiring plate and insert 2
new AA alkaline batteries in place
of the empty ones. Then reattach
the thermostat to the wiring plate.
