Assembly instructions | LK Receiver Unit Cq 1 (NC)
The unit is complemented with a LK Transformer
230/24V AC (article order separately)
The controlling device moves once a day in order
to prevent valves from sticking in a closed posi-
tion. If no valve movement is wanted, the function
can be disconnected by removing jumper 1 on the
thermostat. Remove the dial of the thermostat,
loosen the screws and remove the cover. Remove
jumper 1, marked BR1 on the circuit board.
Installation
A 230 Volt wall outlet should be available nearby
the receiver unit. The receiver unit may only be
installed by a suitably qualified professional ac-
cording to the wiring diagram and in accordance
with valid safety regulations. In order to achieve
protective level 2, the necessary installation mea-
surements must be taken.
Connect 230 V to terminals N and →
Coupling of controlling devices
Controlling devices are coupled between termi-
nal 9 on Cq 1 and one of the 24 Volt cables of the
LK Transformer.
If many controlling devices are to be connected,
they are coupled parallel to each other and in
series with the transformer, see wiring diagram.
Then connect the second 24 Volt cable of the trans-
former to terminal 2 on the Cq 1.
