5.2.3 Support ring

The valves from dierent manufacturers may have tol-

erance ﬂuctuations that make the radiator thermostat

more loosely seated on the valve. In this case, the pro-

vided support ring (R) should be placed into the ﬂange

before mounting the radiator thermostat (see ﬁgure 5).

5.3 Adaption run

Once the batteries have been inserted, the motor

reserves. Meanwhile, “ ” and the activity

symbol ( ) are displayed.

After the radiator thermostat has been mounted suc-

cessfully, an adaption run ( ) has to be per-

formed in order to adapt the device to the valve. To do

this, proceed as follows:

• As soon as “ ” is displayed, press the con-

trol wheel/boost button (E) to start the adaption run.

Now the actuator performs an adaption run. “ ”

and

the activity symbol ( ) are displayed. During this time,

no operation is possible. After the adapting run has been

successful, the display returns back to normal.

If the adapter run has been initiated prior to mount-

ing or if an error message (F1, F2, F3) is displayed,

press the control wheel/boost button (E) and the

motor reverses to the “ ” position.
