Analog room unit for room temperature control. Room temperature measurement, digi-
tal setpoint readjustment on the unit, energy saving button for setpoint changeover.
Digital room unit for remote room temperature control. Room temperature measure-
ment, 7-day heating program, adjustable temperature setpoints, direct setpoint read-
justment, energy saving button for setpoint changeover, holiday programming, connec-
tion of QAW44 remote sensor or teleswitch.
Electronic control unit for the control of an electromotoric actuator or an apartment
pump by means of the low-voltage control signal delivered by the WRI80.
Acquires and stores the pulses delivered by commercially available pulse counters,
monitors the connection to them, and delivers the cumulated consumption values, error
messages, etc., via the building bus.
Facilitates connection of a QAC22 outside sensor to the building bus.
Service unit for parameterizing SYNERGYR
®
components in the apartments, for col-
lecting billing data from plant without central unit, and as a tool for diagnostic tasks.
Electronic metering device. Acquires the flow rate and the temperature differential,
calculates the amount of heat energy consumed and transmits the data to the WRI80
via M-bus. Must be mounted in the return.
one valves with electromotoric actuators. They control the volumetric flow based on the
signals received from the WRI80.
2-position controllers for controlling the temperature in individual rooms with the help of
radiator valves and thermal actuators.
Specifically matched to the requirements of the SYNERGYR
®
system. Interconnects
the components of the SYNERGYR
®
system and features a 4-wire connection (data
bus and power supply). The data bus conforms to the UTE/CEF46621…46623 stan-
dard.
2-wire connection (point-to-point interface) for connecting the room unit to the WRI80.
Maximum extension is 125 m with a copper cable of 1.0 mm
