Pump control for Cq 4 and Cq 6

Channel 4 or channel 6 can be used for zone control 
(e.g. a room) or alternatively to start/stop a circulation 
pump. Pump control can be arranged via an external 
relay for 24/230 V. For further information, please contact
LK Technical Backup.

Range control of Radio signal

To determine a connection’s maximum range, the following
check can be carried out:
•  First, carry out activation/memorizing as the instructions.
•  Then push the “Reset” button on the receiver unit at 
  the same time as the button for “Channel 2”.
•  First release “Reset” followed by the “Channel 2” 
  button. The sound signal and the indicator light will now
  pulse for about 2 seconds on, 8 seconds off.
•  Next move the room thermostat far enough away from
  the receiver unit that the pulses almost stop. This is 
  the maximum distance for radio connection.
•  Finish the check by pressing “Reset” on the receiver unit.

The room thermostat returns to normal operation mode 
after a short time. Other channels are not affected by the 
check. If the connection is insuf

Þ

 cient, the radio signal

can be strengthened with another aerial. See the section
“LK Antenna Cq”.

Heating & Cooling

The equipment is constructed so that it can be used to heat
(under 

ß

 oor heating) and cool. The functions are changed

manually. When supplied, the components are set for heat.
Switching to cool can be done in two ways.

Alternative 1
Change all room thermostats by moving the mains switch
A to the upper position.

Alternative 2
Changing the whole installation by reprogramming the 
receiver unit as follows:

Change to cool (summer operation):
•  Press the “Reset” button and the button for ”Channel 3”
  at the same time.
•  First release “Reset” followed by “Channel 3”. 

Change to heat (winter operation):
•  Press the “Reset” button and the button for ”Channel 4”
  at the same time.
•  First release “Reset” followed by ”Channel 4”.

NB: For the Cq 1 unit, the change is made on the room
thermostat.

Alarm

When a fault occurs, the indicator light begins to 

ß

 ash with

an irregular time interval and a sound signal is heard. During
signal disruption, the affected channel will deliver approxi-
mately 70% heat output.

Temporary interruption

If no signal is received from the room thermostat (trans-
mitter) for a period between 1 to 10 hours, the indicator 
light on the receiver unit will display short 

ß

 ashes, but 

no sound signal. Acknowledgment of the alarm occurs 
automatically if the transmitter signal reoccurs.

Prolonged interruption

If no signal is received from the room thermostat (transmit-
ter) for a period of more than 10 hours, the indicator light
on the receiver unit will display short 

ß

 ashes and a sound

signal is emitted. Acknowledgment of the alarm occurs 
automatically if the transmitter signal is regained. In the
event of a loss of power in the receiver unit, no pro-
gramming will be affected. Operation will continue as 
normal once power is restored.

Acknowledgment of the alarm

To acknowledge a disruption, interrupt “Memorizing”, or
end a connection test, press “Reset” on the receiver unit.
The output will return to the basic position. When the next
control signal comes after approximately 10 - 20 minutes,
the output will return to its correct position. Any radio 
connection established will not be affected.

Valve exercising  

The actuator disconnects once a day for 3 minutes and 
opens the valve on the heating circuit distributor. This 
function prevents valves from sticking, for instance, during
the summer period. 

If valve exercising is not required, this function can be 
disconnected using vertical 1 in the room thermometer. 
Remove the temperature dial, loosen the screw and lift
the cover. Remove vertical 1, which is marked with BR1 on
the printed circuit card.
