FAULTS UNRELATED TO THE REGULATOR
Stiff valve
Uneven temperature
Not enough heat
Clean the valve axle and the hole of the lid ange, and replace the O-rings of the axle with new ttings
or replace the valve. (Note! This work is usually performed by a plumber)
If the oor heating drainage water level is too high, the oor heating thermostats may prevent normal
circulation of water operated by the control valve. Reduce the level of drainage water to a minimum.
Ensure that there is enough heat available (i.e. boiler or accumulator temperature must be higher than
drainage water temperature). Also, ensure that the piping pressure level is sufcient and that the cir-
culation pump is running.

HINTS FOR FIRST-TIME USE
If room temperature measurement is not in use: At rst the radiator thermostats should be turned fully open. Set the ne adjust-
ment so that the rst time there is below freezing temperatures outdoors, the room temperature stays about 1 °C higher than what
you want it to be. After that turn down the radiator thermostats just enough to obtain the desired room temperature. This prevents
the room temperature from dropping on windy days, because the radiator thermostats will be able to increase the heating level.
Room temperature measurement in use: Room control can, if necessary, raise or lower the temperature level of the whole house
and so the small temperature increase in the network mentioned before is not needed. Also you get more even temperature con-
trol in houses with oor heating when room temperature measurement is taken into use.

ically damaged. The warranty does not cover indirect or consequential loss or damages. It does not cover the cost connected with
