3. Confirm chosen channel
When the thermostat has "found" its channel the
sound signal from Cq1 becomes silent and the in-
dication light on Cq1 shuts off. Confirm by pres-
sing once on the upper black button of the ther-
mostat (C). The LED on the thermostat shuts off
and the diode on the receiver unit will flash a few
times. The programming is now complete.
Functional control
Test the connection by turning the knob of the
thermostat up/down. When the thermostat is at
the maximum position, the indication light on
Cq1 should be on and when the thermostat is at
the minimum position, the indication light of the
Cq1 should be off.

ruptions
Problems with signal transmissions
If the signals between the thermostat and receiver
unit are not transmitting correctly, the signal light
on the receiver unit will flash. During the ongo-
ing signal interruption, the output of the channel
concerned will produce a 30% effect. If the recei-
ver unit receives signals from thermostat concer-
ned, the alarm is stopped immediately.
If the problem remains for more than 10 hours, an
alarm signal will sound in addition to the signal
light. The problem can be attended to by pressing
on the reset button (button C) of the thermostat,
see heading "Programming/Commissioning". If
the problem returns, the batteries of the thermo-
stat concerned may require changing; see heading
"Battery Exchange" for more information. If the
problem returns despite battery exchange, it may
be necessary to strengthen the signal, which can
be suitably done with the help of a LK Repeater.
See more in separate instructions for the LK Re-
peater.
The controlling devices do not shut off
Check that there is power supplied to the outlet.
Check the fuse of the transformer. Remove the
plug before changing the fuse. Change to the same
type of fuse as is already present, 250 V 6.3 A.

Power failure
If power failure occurs, no data is lost, all pro-
gramming is saved. When the power returns, it
may take up to ten minutes before the unit has
reverted to normal operation. The process can be
hastened by pressing on the upper black button
(C) of the room thermostat.
Battery exchange of room thermostat
LK Room Thermostat Cq is delivered with two
1.5 V batteries (LR03). The batteries have an esti-
mated working life of two years. The signal light
on the thermostat flashes at 15-second intervals
when it is time to change the batteries. The bat-
teries should be exchanged within the next few
days; the batteries are located under the lid of the
thermostat cover. The thermostat reverts to the
chosen mode of operation after battery exchange.
Press on the reset-button of the thermostat to has-
ten return to the chosen mode of operation (but-
ton C), see image under heading "Programming/
Commissioning". Uncharged batteries yield a 30
% heat effect on the receiver unit.
