The regulated underfloor heating circuits are operated
by the external heating circuit pump from the buffer
cylinder via a mixer. Flow temperature sensor VF2 is in-
stalled downstream of the diverter valve in the heating
flow (necessary for cooling function).
The heat pump responds to a demand for heat from the
buffer cylinder.
The brine pump is only included with VWS.
