If the controller is connected to the bus, the room temperature can be transmitted and
received via bus. In addition to the room zone, the controller must have a valid device
address set.
With default address 255, there will be no communication via bus.
If the room temperature is acquired directly at the device, it will be transmitted in the
heating circuit’s room zone (geographical zone (apartm.)) via bus so that it will become
available to all devices on the bus.
The room temperature can also be acquired by bus-compatible room sensors or room
units (e.g. QAW740) and be sent directly via bus. The associated room zone
(geographical zone (apartm.)) is to be set at the sensor or room unit.
The room temperature transmitted via bus is received by the heating circuit, provided
the room zones (geographical zone (apartm.)) of the transmitter accord with those of
the receiver.
The following variants are available:

1 room sensor directly
connected
The heating circuit operates
with its own room temperature.
When communication is
activated, the room
temperature signal will be
delivered throughout the
heating circuit’s geographical
zone

Synco
2 room sensors directly
connected
The heating circuit operates
with the average value of the 2
sensors.
When communication is
activated, the average value
will be delivered throughout
the heating circuit’s
geographical zone as the room
temperature
