H2 pump Q18
Pump H2 can be used for an additional consumer. Together with an external demand
for heat at input H2, it is possible to serve an air heater or similar.
System pump Q14
The connected pump serves as a system pump for supplying heat to other consumers.
The system pump is put into operation as soon as one of consumers calls for heat. If
there is no demand for heat, the pump will be deactivated followed by overrun.
Time program 5 K13
The relay is controlled according to the settings made in time program 5.
DHW mixing pump Q35
Separate pump for storage tank circulation during the time the legionella function is
active.
DHW interm circ pump Q33
Charging pump with DHW storage tank using an external heat exchanger.
Heat request K27
As soon as there is demand for heat, output K27 is activated.
Refrig demand K28
As soon as there is refrigeration demand, output K28 is activated.
In the case of the device with address 1, a refrigeration demand from the system can
activate output K28. For this purpose, operating line 6627 "Refrig demand K28" on the
operating page "LPB system" must be set to "Centrally".
Dehumidifier K29
An external dehumidifier can be enabled if the indoor air humidity rises. In this case, a
humidity sensor must be connected to the H... input.
The function of the dehumidifier depends on the cooling functions.
The operation of the dehumidifier is not affected by operating modes, holiday programs,
occupancy buttons etc.
Diverting valve, cooling Y21
With common distribution to the heating and cooling circuits, the inputs/outputs are
always on the mixing valve group on the basic unit. For a 4-pipe system, diverting valve
Y21 is also required.
