Primary controller without outdoor sensor:
The controller is configured for demand-driven heat exchanger control with control of the
feeder pump. Operation of the feeder pump and heat exchanger control are exclusively re-
leased by the received demand signal, not over a time schedule. Demand signals between
1 V and 10 V activate the feeder pump and cause the requested flow temperature (at least
20 °C to 120 °C) plus the adjusted Boost to be adjusted. Demand signals below 1 V are not
processed; they cause the primary valve to be closed and deactivate the feeder pump with a
certain delay. The deactivation delay for the feeder pump can be adjusted.
