DHW: The diverting valve (DV) goes into the DHW position after the last
request has ended.
DHW separate circuit (5736)
For multi-boiler systems (cascades), a heat generator can only be
temporarily used for charging the domestic hot water. When active
charging is carried out, this boiler separates itself hydraulically from the
system using a domestic water isolating circuit and is no longer available
for the rest of the time that heating mode is active.
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.
Important
For a domestic water isolating circuit, the DHW ctrl elem Q3 must
be set to "Diverting valve" under program no. 5731.
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 circuits.
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.
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
instead 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
together
for DHW and
buffer storage or only
for one of the two
.
Combi storage tank (5870)
Combined storage-specific functions are activated with this setting. For
instance, 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.
Relay output QX1 (5890) , Relay output QX2 (5891) and Relay
output QX3
None: Relay outputs deactivated.
Circulating pump Q4: The connected pump serves as a DHW circulation
pump (see prog. no. 1660).
