Control and Heating
Cost Allocation Valve
WRV82...
with acquisition of the flow temperature per zone
Electronic metering, control and regulating unit. Controls the room temperature
through regulation of a valve. Acquires the pressure drop across the valve as an
auxiliary measuring variable for the flow rate and uses the auxiliary measuring
variable "temperature" to calculate the proportional energy consumption. Ac-
quires pulses from non-SYNERGYR meters, stores data, and communicates with
other SYNERGYR units via building bus.
The control and heating cost allocation valve WRV82... is a component of the
SYNERGYR Control & Metering System. For field of use of the system, refer to data
sheet 2801.
