Min st tank temp heat mode (4724)
If the storage tank temperature of the buffer storage tank drops below this
value, the heating circuit is switched of if no generator is available.
Charging temp max (4750)
The buffer storage tank is charged from solar energy up to the set
charging temperature maximum.
Important
The collector overheating protection function can reactivate the
collector pump until the maximum cylinder temperature (90 °C)
has been reached.
Recooling temp (4755)
If it was necessary to charge the buffer storage tank to above the
maximum charging temperature (program no. 4750), recooling down to the
recooling temperature set here is carried out as soon as possible. Two
functions are available for recooling the buffer storage tank down to the
recooling temperature (see program no. 4756 and 4757).
Recooling DHW/HCs (4756)
The energy can be discharged via a heat draw by the room heating or the
domestic water storage tank. This can be set separately for each heating
circuit (see program no. 861, 1161, 1461).
Recooling collector (4757)
Recooling when the buffer storage tank temperature is too high by
transmitting energy to the environment via the collector area.
Off: Recooling has been deactivated.
Summer: Recooling is only active in summer.
Always: Recooling is always active.
With solar integration (4783)
Setting of whether the buffer storage tank can be charged by solar energy.
Temp diff on return div (4790), Temp diff off return div (4791)
and Compar temp return div (4795)
At the appropriate temperature difference between the return sensor B73
and the selectable comparative temperature the return is re-routed to the
lower buffer storage tank section. The function can either be used as
return temperature increase or as return temperature decrease. The way
this works is defined in prog. no.4796.
Using the definition of the temperature differences in prog. no. 4790 and
4791 the switch on and switch off point of the return redirection is
established.
In prog.no. 4795 the buffer storage tank sensor is selected that delivers
the value for the comparison with the return temperature, to switch on the
return redirection with the aid of the set temperature differences.
Important
To activate the return redirection, a Qx relay output (program no.
5890-5892) for the Y15 buffer deflector valve and a Bx sensor
input (program no. 5930-5932) for the B73 common return sensor
must also be configured.
Optg action return diversion (4796)
The function can either be used as return temperature increase or as
return temperature decrease.
Temp decrease: If the return temperature of the consumers is higher
than the temperature on the selected sensor (prog. no. 4795), the lower
part of the storage tank can be preheated with the return flow. The
return temperature drops even lower with this, which leads to a higher
efficiency with a condensing boiler, for example.
