Hot water ctrl elem Q3 (5731)
No charging request: DHW charging disabled via Q3.
Charging pump: DHW charging via the connection of a charging pump
to Q3/Y3.
Diverting valve: DHW charging via the connection of a diverting valve to
Q3/Y3.
Basic pos HW div valve (5734)
The base position of the diverting valve is the position in which the divert­
ing valve (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.
Central heating: The diverting valve (DV) goes into the heating circuit
position after the last request has ended.
Hot water: The diverting valve (DV) goes into the DHW position after the
last request has ended.
Hot water separate circuit (5736)
The DHW separate circuit can only be used in a boiler cascade.
Off: The DHW separate circuit function is disabled. Each available boiler
can feed the DHW storage tank.
On: The DHW separate circuit function is enabled. The DHW charging is
only done from the boiler defined for this.
Note
The DHW actuator Q3 must be set under prog. no. 5731 to "Di­
verting valve" for a DHW separate circuit to become effective.
Ctrl boiler pump/HW 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 ex­
ternal consumer circuits.
All requests: The diverting valve is connected hydraulically for all re­
quests and switches between DHW mode and the remaining requests.
The boiler pump runs for all requests.
Request CH1/HW 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 hydrauli­
cally via the diverting valve (DV) and the boiler pump, but rather directly
connected to the boiler.
Boiler pump at DHW (5775)
This parameter determines, whether the boiler pump for DHW charging is
switched on or off.
Solar controlling element (5840)
The solar heating system can also be operated with charging pumps in­
stead of with a collector pump and diverting valves for the storage tank
connection.
Charging pump: When used with charging pump all exchangers can be
flowed through simultaneously. Parallel or alternative mode is possible.
Diverting valve: When used with a diverting valve only one exchanger
can be flowed through. Only alternative mode is possible.
External solar exchanger (5841)
For solar schemes with two storage connections it must be set whether the
external heat exchanger is present and is used
for one of the two .
fer storage or only
Combi storage tank (5870)
Combined storage-specific functions are activated with this setting. For in­
stance, the buffer storage immersion heater can be used for heating as
well as for DHW.
No: No combined storage exists.
Yes: A combined storage exists.
