Thank you for purchasing Thermostatic Radiator Valve HT-10R from VOLT Polska. Please read this user
manual before starting the device.
Thermostatic Radiator Valve HT-10R senses 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 thermostatic radiator valve HT-10Rto suit each room and
then leave them to do their job.
Turning a thermostatic radiator valve HT-10R 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
thermostatic radiator valve HT-10Rto a lower setting will result in the room being controlled at a lower
temperature, and saves energy.
Thermostatic Radiator Valve HT-10R needs a free flow of air to sense the temperature so they must not be
covered by curtains or blocked by furniture.
