A built-in flow direction selection feature can be used to eliminate the risk of water hammer. If the flow direction needs to be changed, simply turn the setting ring.

• Page 2: Installation guide User guide Fitting the sensor Setting the desired room temperatures The desired room temperature is set by turning the head. The thermostat opens and closes as determined by the temperature around it. The sensor must never be hidden behind thick curtains, furniture, etc. A thermostatic radiator valve (TRV) senses the air temperature around it and regulates the flow of water through the radiator. TRVs need a free flow of air to sense the temperature. Turning a TRV to a higher setting will not make the room heat up any faster.
