Temp diff buffer/HC
(4722)
If the temperature difference between buffer storage and heating circuit tempe-
rature request is sufficiently large, the heat required by the heating circuit will be
taken from the buffer storage. The heat generator is locked.
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 tem-
perature maximum.
The collector overheating protection function can put the collector pump back in
operation until the maximum storage tank temperature is reached.
Recooling temperature
(4755)
The collector overheating protection function can put the collector pump back in
operation until the maximum storage tank temperature is reached.
Recooling DHW/HCs
(4756)
For the recooling of the buffer storage tank to the recooling temperature there
are two functions available.The energy can be discharged via a heat draw of the
room heating or the DHW storage tank. This can be separately set for each hea-
ting circuit.
Recooling collector
(4757)
Recooling with a too high buffer storage tank temperature by transmission of
energy to the environment via the collector area.
- Off : recooling is switched off.
- Summer : the recooling is only active in the summer.
- Always : recooling is always active.
With solar integration
(4783)
Setting of whether the buffer storage tank can be charged by solar energy.
Return diversion
(4790 - 4795)
At the appropriate temperature difference between the return sensor B73 and
the selectable comparative temperature the return is re-routed to the lower buf-
fer storage tank part. The function can either be used as return temperature inc-
rease 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 redirecti-
on 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 sensor B73 must also be configured.
