What is a thermostatic radiator valve (TRV)?

..an explanation for householders  
room being controlled at a lower  
temperature, and saves energy.  
User Manual  
TRVs sense the air temperature around them and  
regulate the flow of water through the radiator which  
they are fitted to. They do not control the boiler.  
TRVs need a free flow of air to  
sense the temperature, so they  
must not be covered by curtains  
or blocked by furniture.  
They should be set at a level that gives you the room  
temperature you want. These settings may have to be  
different in each room, and you should set the TRVs to  
suit each room and then leave them to do their job.  
TRVs cannot turn off the boiler when the whole house  
is warm. To do that, you will need a room thermostat as  
well. The radiator in the room with the room thermostat  
should normally have a TRV, but, if it does, keep the  
TRV on the maximum setting and adjust the room  
thermostat as explained with the instructions.  
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 the TRV to a lower setting will result in the

Valve installation  
Remove protective cap and connect fittings to radiator and hot water source as shown below. If necessary, cut  
supplied copper tubes to an entry depth of 10 mm into the TRV to ensure a secure connection.

Lockshield valve  
(optional)  
The TRV can be installed on either side  
of the radiator, in a vertical or horizontal  
position, as shown at left.  
Cap  
If a lockshield valve is also used on the  
same radiator, install it on the opposite  
side of the radiator, as shown.

Sensor installation  
Temperature control  
Check all fittings to make sure connections are secure before installing the thermostat sensor. Center the sensor  
over the radiator valve, push down and screw firmly into place as shown below.  
Turn the sensor to control temperature at each radiator fitted with a TRV. Settings are marked with numbers rather  
than temperatures, because heating systems vary. An approximate guide follows, below. You may have to adjust  
the sensor for a day or two, to get the proper setting for the temperature you prefer.  
After installation, set the sensor to an appropriate temperature level, then turn on the boiler or open valves as  
needed to resume hot water flow to the radiator. Watch carefully to check for leaks. If leaks occur, stop hot water  
flow to the radiator immediately and check all fittings.

NOTE: To ensure accurate temperature control, make sure the TRV is exposed to a free flow of  
room air, and is not blocked by draperies or furniture.  
NOTE: Temperatures listed above are estimates based on typical performance after vertical mounting.  
Temperatures may vary by 1° to 2° C if the TRV is installed in other positions.
