Danger!

Live connections!

When working in the control cabinet of the ap-

pliance there is a danger to life by electric

shock.

Switch the power supply off before working in

the control cabinet and secure against re-con-

nection.

Open the control cabinet only when the appli-

ance is potential-free.

If the radio receiver unit is integrated into the appliance,

the electrical connection is established through contact

between the plug connector of the controller and the

corresponding plug connection in the appliance.

5.1 Electrical installation of the radio receiver

when mounting it on a wall

Note!

The radio receiver only needs to be wall-mount-

ed if, after start-up, the receiver position has

to be changed in order to establish the best

connection with the controller and the outdoor

sensor.

The power supply to the appliance must be disconnect-

ed and prevented from being unintentionally switched

back on.
