What is a Thermostatic Radiator Valve (TRV)?

How do they work?

Why do I have them fitted in my home?

RAS-D2 TRV

INTRODUCTION

The radiators in your home are fitted with a THERMOSTATIC

RADIATOR VALVE (TRV). This TRV enables you to have individual

rooms set at different temperatures for your heating comfort and

helps with heating economy.

Once set, the TRVs must NOT be operated like a normal valve,

which is either open or closed.

HOW THE TRV WORKS

When the air temperature of the room reaches the setting on the

dial, the TRV will turn the radiator off. The radiator will stay off

until the room temperature falls sufficiently for the TRV to turn

the radiator back on. This automatic turning on and off will keep

the room at a steady temperature. Individual rooms can be set

for different temperatures. This cooling of the radiator is a sign

that the TRV is working as it should.

SETTING THE TEMPERATURE

Turning the dial sets the thermostat; it should be set to a number

which gives you a comfortable temperature in the room, then

LEFT ALONE. For example, if the dial is set to 3 and you are not

warm enough, turn the dial up to the number which provides

the temperature you are comfortable with.
