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.
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.
* Frost Protection
If you leave your home for a longer period of time, you can safely
turn the thermostat to *. At this setting, the temperature will keep
the room temperature at about 7-8 0C.
Night Setback
To save energy, simply lower the room temperature at night or at
times when nobody is at home.
Cleaning
The radiator thermostat can be cleaned with mild detergents such
as dish washing liquid. Do not use scourers, alcohol, solvents or
bleaching agents as they can damage the radiator thermostat.

Connect the H-piece to the copper
inserts and tighten the union nuts.
Screw both of the removed brass
inserts into the radiator and tighten
with a 10 mm Allen key.
