With the Eco application of the WRI80, SYNERGYR
®
provides room temperature con-
trol and must have a suitable reference room in each apartment. In the other rooms, the
room temperature is controlled by thermostatic radiator valves. Room temperature
control of the reference room always takes place via the zone valve.
The WRV81 is to be replaced by a WRI80, a Siemeca™ M-bus heat meter and a mo-
torized zone valve.
With the Comfort application of the WRI80, SYNERGYR
®
provides room temperature
control during occupancy times via the room valve; the zone valve remains open (indi-
vidual control of the other rooms, depending on demand).
During nonoccupancy times, central night setback is ensured via the zone valve.
The WRV84 is to be replaced by a WRI80, a Siemeca™ M-bus heat meter and a mo-
torized zone valve.
With the Standard application of the WRI80, SYNERGYR

without room temperature control.
The WRV83 is to be replaced by a WRI80 and a Siemeca™ M-bus heat meter.
