Recooling HW/CHs (4756)
Two functions are available for recooling of the buffer storage tank down
to the recooling temperature. The energy can be discharged via a heat
draw by the room heating or the DHW storage tank. This can be separate­
ly set for each heating circuit.
Recooling collector (4757)
Recooling when the buffer storage tank temperature is too high by trans­
mitting 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)
andCompar 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 re­
turn 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 estab­
lished.
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.
Note
To activate the return redirection the relay outlet QX1, QX2, QX3
(prog. no. 5890-5892) for the buffer deflector valve and the sensor
inlet BX1, BX2, BX3 (prog. no. 5930-5932) for the rail return sen­
sor B73 must also be configured.
Optg action return diversion (4796)
The function can either be used as return temperature increase or as re­
turn 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 re­
turn temperature drops even lower with this, which leads to a higher effi­
ciency with a condensing boiler, for example.
Temp increase: If the return temperature of the consumers is lower than
the temperature on the selected sensor (prog. no. 4795), the return flow
can be preheated by redirecting over the lower part of the storage tank.
In this way, for example, return flow preheating can be implemented.
Full charging (4810)
full charging makes it possible for the released generator to
The function
be switched off first despite automatic generator lock if the buffer storage
tank is fully charged. During active function the generator parameterized
for the full charging function is only switched off when the full charging set­
point is reached or the boiler must be switched off because of burner con­
trol.
Off: The full charging function is switched off.
Heating mode: Full charging becomes active if the automatic generator
lock blocks the heat source during valid heat request based on the buf­
fer temperature. If the buffer storage tank reaches the requested tem­
perature at the sensor parameterized for the full charging function, the
function is ended.
Always: Full charging becomes active if the automatic generator lock
blocks the generator during valid heat request based on the buffer tem­
perature or the heat request is invalid. If the buffer storage tank reaches
