•  Press the ”Reset” button and the button        at the same
 time. 
•  First release the ”Reset” button, followed by the  button
       .
•  Press ”Reset” again.

LK Room Thermostat Cq  

Open the door on the room thermostat and remove the 
transport protection covering the batteries.

Check the mains switch (A) is in the lower position towards
the heat symbol as shown in the picture. During memo-
rizing, the thermostat will attempt to communicate with 
the activated channel on the receiver unit. Memorizing 
can take place before the thermostat is assembled in the 
intended place. The distance between the thermostat
and the receiver should be at least 2 metres during 
memorizing.

NB: Mark the thermostat with the channel number that
it will be sent to. (e.g. with tape on the inside of the door.)

Cq 1 Receiver Unit 

Cq 1 Receiver Unit differs from the other units as up to eight
actuators can be connected.

Up to two actuators can be connected direct to Cq1.
However, if necessary, it is possible to connect up to 
eight actuators to Cq1 by using an external wiring / 
junction box. In both cases the actuators are connected 
parrallel to each other and in line between terminal 9 
and the LK Transformer.

LK Transformer 230/24 V AC  

A transformer 60 VA for 24V AC supply is connected in 
accordance with the circuit diagram for each receiver unit.

  

230V mains voltage connection  

•  Connect the receiver unit and the transformer to the
 mains. 
•  Check the primary and secondary voltage. 
•  Reassemble the protection box on the receiver unit 
  before Memorizing/Start-up.

programming.  

For Cq 4 and Cq 6 as follows:  
•  Press the ”Reset” button and the button for ”Channel 
  1” at the same time. 
•  First release the ”Reset” button, followed by the  
”Channel 1” button.
