Activating the receiver

For Cq 4 and Cq 6 as follows:
• To activate the memorizing phase on the receiver unit, 
  press the button for the channel that is to be activated 
 

Þ

 rst. A weak sound signal is heard and the indicator 

  light will come on.
 
For Cq 1 as follows:
• To activate the memorizing phase on the receiver unit, 
  press the button     . A weak sound signal is heard 
  and the indicator light will come on.

Activating the room thermostat

•  Press and hold the lower black button (B).
• Brie

ß

 y press the upper black button (C).

•  When the indicator light (D) is lit, release the lower 
  button. Memorizing (the connection) between the 
  thermostat and the channel selected now occur. Pay 
  attention to the receiver. Once contact is established, 
  the sound signal will cease and the indicator light will 
 go 

out.

•  Press the upper button on the room thermostat one 
  more time to switch off the indicator light. (The indicator
  light on the thermostat in future use is only used to 
  warn of low battery power.)

Function control  

Place the room thermostat in the room where it is intended
to be assembled according to the design. By turning the 
thermostat’s adjustment dial, the indicator light on the 
receiver’s channel will be lit or switched off respectively 
within approximately 30 seconds.
•  Dial towards maximum temperature, the light on the 
  receiver unit comes on.
•  Dial towards minimum temperature, the light on the 
  receiver unit goes off.

  NB: The receiver Cq 1 works the opposite way.

If the light switches off when it should come on, check 
that the mains switch’s setting is in the lower position 
towards the heat symbol. See the section LK Room 
Thermostat Cq. If the setting was right and the problem 
continues, see the section ”Heat/Cool”.

NB: During set up (only) the indicator light on channel
4 or channel 6 comes on when one or more other 
channels trigger the heating. This function continues 
until all the channels are activated. For more informa-
tion, see the section “Pump Control”.

ADDITIONAL MEASURES

Assembling the room thermostat

Open the room thermostat by pulling the temperature scale
dial right out and loosening the screw that becomes visible.
Bend out the upper part to the left until it becomes loose. 
Position the room thermostat as per the design plan.

For the room thermostat to function properly, the fol-
lowing guidance should be followed:
•  Mount it on an inner wall where it is ventilated but not 
  in a draught. (NOTE FOR UK: in some home refurbish-
  ment projects where the building is poorly insulated, it
  may be prudent to place the thermostat on an outside, or
  coldest, wall. The thermostat will then compensate by
  calling for heat.)
•  Do not expose it to direct sunlight or other heat sources.
•  Mount it approximately 1.5 metres above the 

ß

 oor.

•  Do not mount it near a radio, TV or other transmitter.
•  Do not mount it near metal objects, such as metal doors,
  metal cupboards or similar.

Completing activation / memorizing

Continue activation / memorizing in the same way as for
the other channels, following the instructions for the 
LK Room Thermostat Cq.

LK Antenna Cq  

The LK Antenna Cq is intended to be used when the radio
connection between the room thermostat and the receiver
unit is unsatisfactory.

The antenna is assembled as follows:
•  The antenna holder is supplied with self-adhesive tape
  and is attached to the top of the receiver unit. The 
  stripped part of the antenna is pulled through the 
  antenna holder until it appears on the other side.
•  The other end of the antenna is pulled to the outside 
  of the enclosure and is assembled in the same way, 
  placed at least 200 mm from any metal objects.
