PWM-output P1
(6085)
With this parameter the function for the modulating pumps is specified. If becau-
se of the function no modulating signal can be calculated internally, then 0 % for
Off or 100 % for On is output.
- None : No output P1 exists.
- Boiler pump Q1 : the connected pump is used for recirculation of the boiler wa-
ter.
- DHW pump Q3 : Control element for drinking water storage.
- DHW interm circ pump Q33 : Charge pump for domestic hot water storage with
external heat exchanger.
- Heat circuit pump HC1 Q2 : the heat circuit pump HC1 will be activated.
- Heating circuit pump HC2 Q6 : the heat circuit pump HC2 will be activated.
- Heating circuit pump HC3 Q20 :the heat circuit pump HC3 will be activated.
- Collector pump Q5 : a circulation pump for the collector circuit is required for
connection of a solar collector.
- Solar pump ext exch K9 : if several exchangers are connected, the buffer storage
must be set at the respective relay output. and the type of the solar regulating
unit must be defined in prog.no. 5840.
- Solar pump swi pool K18 : if several exchangers are connected, the the swim-
ming pool must be set at the respective relay output. and the type of the solar
regulating unit must be defined in prog.no. 5840.
