...an explanation for householders

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.

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.

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

room being controlled at a lower temperature, and saves energy.

TRVs need a free ﬂow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture.

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.

Valve installation

OUT (cool) OUT (cool)

NOTE: If you are not experienced in equipment installation, we recommend that these procedures be done by a professional installer.

ALLOW RADIATOR TO COOL BEFORE INSTALLATION: To avoid injury, turn off boiler or stop hot water ﬂow to radiator and allow it to cool before installation.

Lockshield valve (optional)

The TRV can be installed on either side of the radiator, in a vertical or horizontal position, as shown at left.

If a lockshield valve is also used on the same radiator, install it on the opposite side of the radiator, as shown.

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.

NOTE: Keep the protective cap. You can remove the thermostat sensor (see next page) and screw the cap back into place to prevent water overﬂow if you must remove the radiator later.

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.

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.

Temperature sensor

Hand-tighten only. Do not use tools.

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.

Limited warranty

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.

0 1° C (potential hazard of freezing)

* 6° C (frost protection level)

1 12° C

Turn to regulate temperature

2 16° C

3 20° C

4 24° C

5 28° C

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.
