User Guide
What is a thermostatic radiator valve (TRV)?
TRVs sense the air temperature around them and regulate the ow
of water through the radiator which they are tted to.
They should be set at a level that gives you the room temperature
you want. These settings may have to be dierent in each room,
and you should set the TRVs to suit each room and then leave them
to do their job. As guide to the temperatures is shown on the right.
Turning a TRV to a higher setting will not make the room heat up
any faster. How quickly the room heats up depends on the boiler
size and setting, and the radiator size. Turning a TRV to a lower setting will result in the room being controlled at a lower temperature,
and saves energy.
Set and Forget
The thermostat maintains a constant temperature in your room, set
your preferred room temperature according to the thermometer
below and that’s it. The thermostat will open and close depending
on the heat demand thereby utilizing the free heat from sunlight,
appliances and people.

as dish washing liquid. Do not use scourers, alcohol, solvents or
bleaching agents as they can damage the radiator thermostat.

Additional heat saves energy
Sunlight, kitchen appliances and electric light give o additional
heat. The thermostat registers such additional heat by automatically closing down. When there no longer is enough additional heat
available, the thermostat automatically opens again.
Please do not cover the thermostat!
The thermostat must be able to register the temperature of the
room. If it is covered by e.g. thick curtains or furniture, use a thermostat with remote sensor.
