Several clock thermostats and wireless receivers can be installed in a single
building. Both are matched up to each other in the factory. If several clock ther-
mostats are fitted with the wireless receiver in a single building complex, never
swap the respective clock thermostat and wireless receiver, as each clock ther-
mostat can only communicate with the respectively allocated wireless receiver.
Testing the strength of reception
At the back of the clock thermostat,
turn the rotary selector to
"10"
.
The clock thermostat sends a signal
every 4 s for a duration of 5 minutes.
The reception signal strength is indi-
cated by the number of lit LEDs. See
the following table.
After commissioning, set the rotary
selector of the wireless receiver back
to the required position for DHW heat-
ing (see page 11 ).
