Basicposition DHW diverting
valve
(5734)
The base position of the diverting valve is the position in which the diverting val-
ve (DV) is in if no request is active.
- Last request : The diverting valve (DV) remains after the last request has ended
in this last position.
- Heating circuit : The diverting valve (DV) goes into the heating circuit position
after the last request has ended.
- DHW : The diverting valve (DV) goes into the DHW position after the last requ-
est has ended.
Separate circuit
(5736)
The DHW separate circuit can only be used in a boiler cascade.
- Off : The DHW separate circuit is switched off. Each available boiler can feed the
DHW storage tank.
- On : The DHW separate circuit is switched on. The DHW charging is only done
from the boiler defined for this.
For a DHW separate circuit, under prog. no. 5731, the DHW control element Q3 is
set on "diverting valve“.
Optg action DHW div valve
(5737)
Using this parameter the diverting valve position is set, which applies during acti-
ve output.
- Position on DHW : during active output the diverting valve is in the DHW positi-
on.
- Position on heating circuit : during active output the diverting valve is in the
heating circuit position.
Ctrl boiler pump/DHW valve
(5774)
With this parameter it can be defined for special hydraulic systems that the boiler
pump Q1 and the diverting valve Q3 only are responsible for DHW and heating
circuit 1, however not for heating circuits 2 and 3 or for the external consumer
circuit.
- All requests : the diverting valve is connected hydraulically for all requests and
switches between DHW mode and the remaining requests. The boiler pump
runs for all requests.
- Request HC1/DHW only : The diverting valve is connected hydraulically only for
heating circuit 1 and DHW and switches between DHW mode and heat circuit 1
mode. All other requests are not connected hydraulically via the diverting valve
(DV) and the boiler pump, but rather directly connected to the boiler.
Solar controlling element
(5840)
The solar heating system can also be operated with charging pumps instead of
with a collector pump and diverting valves for the storage tank connection.
- Charge pump : When using with the charging pump all exchangers can be flo-
wed through simultaneously. The parallel or alternative mode is possible.
- Deflecting valve : When using with a diverting valve always only one exchanger
can be flowed through. Only the alternative mode is possible.
External solar exchanger
(5841)
For solar schemes with two storage connections it must be set whether the exter-
nal heat exchanger is present and is used together for DHW and buffer storage or
only for one of the two .
Combined storage
(5870)
Combined storage-specific functions will be activated with this setting. For ins-
tance, the buffer storage electric heater insert can be used for heating as well as
for DHW.
- No : No combined storage exists.
- Yes : A combined storage exists.
