Description of Functions - Room Thermostat
Control occurs using pulse width modulation (PBM), which
is intended for actuators. The control signal, which is calcu-
lated from the difference between the actual temperature
and the temperature entered, is emitted in the form of a
signal 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 thermostat
When the indicator light
ß
ashes with 15-second intervals,
the batteries should be changed within a few days. The
batteries are located under the battery cover. For infor-
mation 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 70% heat output.
Connection check
After using the receiver unit’s “Reset” function, the
respective channel’s indicator light will indicate, by a short
ß
ash, that the connection has been established.
