Alarm
When a fault occurs, the indicator light begins to
flash with an irregular time interval and a sound
signal is heard. During signal disruption, the af-
fected channel will deliver approximately 30%
heat output.
Temporary interruption
If no signal is received from the room thermostat
(transmitter) for a period between 1 to 10 hours,
the indicator light on the receiver unit will dis-
play short flashes, but no sound signal. Acknow-
ledgment of the alarm occurs automatically if the
transmitter signal reoccurs.
Prolonged interruption
If no signal is received from the room thermostat
(transmitter) for a period of more than 10 hours,
the indicator light on the receiver unit will dis-
play short flashes and a sound signal is emitted.
Acknowledgment of the alarm occurs automati-
cally if the transmitter signal is regained. In the
event of a loss of power in the receiver unit, no
programming will be affected. Operation will
continue as normal once power is restored.
Pump control for Cq 4 and Cq 6
The last channels on the receiver Cq 4 (channel 4)
and Cq 6 (channel 6) can start or stop a circula-
ting pump. However, Cq 4 becomes 3 channel
and Cq 6, 5 channel receiver. Pump control can be
arranged via an external relay for 24/230 V (relay
not supplied by LK). The 24 Vside of the relay
should be connected to terminals A and C of the
channels. The channels have a time delay of 10
minutes for pump control.
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 recei-
ver unit at the same time as the button for
“Channel 2”.
•
First release “Reset” followed by the “Chan-
nel 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-
ficient, the radio signal can be strengthened with
LK Repeater Cq. See separate section, LK Repea-
ter Cq.
Heating & Cooling
The equipment is constructed so that it can be
used to heat(under floor 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 switchA to the upper position.
