Connection check
After using the receiver unit’s “Reset” function,
the respective channel’s indicator light will indi-
cate, by a shortflash, that the connection has been
established.

NOTE:
Trouble free operation cannot always be guaranteed due
to possible external interference sources.
Acknowledgment of the alarm
To acknowledge a disruption, interrupt “Memo-
rizing”, or end a connection test, press “Reset” on
the receiver unit. The output will return to the ba-
sic position. When the next control signal comes
after approximately 10 - 20 minutes, the output
will return to its correct position. Any radio con-
nection established will not be affected.
Valve exercising
The actuator disconnects once a day for 3 mi-
nutes 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, loo-
sen the screw and liftthe cover. Remove vertical 1,
which is marked with BR1 on the printed circuit
card.
Description of functions - room thermostat
Control occurs using pulse width modulation
(PBM), whichis intended for actuators. The con-
trol signal, which is calcu-lated from the differen-
ce between the actual temperatureand the tempe-
rature entered, is emitted in the form of asignal
with different pulse and rest ratios. The sum of
the signal and rest period is always 10 minutes.
With large temperature variations, the thermostat
is constantly switching on or off.
Changing the batteries on the room thermo-
stat
When the indicator light flashes with 15-second
intervals, the batteries should be changed within
a few days. The batteries are located under the
battery cover. For information about battery type,
see “Technical data.”
After changing the batteries, the thermostat will
continue to operate according to the chosen mode
of operation. With depleted batteries, the receiver
channel will continuously deliver 30 % heat out-
put.
