When the adjusted value falls below MN3O, the
relay will be deactivated. By exceeding parameter
MN3F, the relay will be activated again. Paral-
lely, the switch on- and switch off temperature
differences DT3O and DT3F apply for both: the
maximum- and minimum temperature limit.
Recommendation: when using buffer tanks
for system 8, following adjustments should be
made: MX3O approx. 80 °C / MX3F approx. 75 °C.
Please note: the parameter MX3O and MX3F
always apply to the heat sink, the parameter
MN3O and MN3F to the heat source.
If the adjusted collector temperature limit (EM /
EM1 / EM2) is exceeded, the solar pump (R1/
R2) is deactivated in order to avoid a damaging
overheating of the solar components (collector
emergency shutdown). The factory setting for the
limit temperature is 130 °C, but it can be changed
within the adjustment range of 110 ... 200 °C.
is displayed (fl ashing).
(only Arr 6 + 10)
When the OSPr function has been activated, the
secondary heat consumer can be additionally
charged in order to spread out the heat quantity
if the limit differential temperature TSPr of the
∆T circuit has been exceeded.
This function can be used with systems 6 and 10.
If the adjusted maximum store temperature is
reached, the solar system switches-off. If now
the collector temperature rises to the adjusted
maximum collector temperature (CMX / CMX1
/ CMX2), the solar pump remains activated until
this limit temperature value is again underrun.
The store temperature might continue to rise
(subordinated active maximum store tempera-
ture), but only up to 95 °C (emergency shutdown
of the store). In order to recool the store to its
maximum temperature, the use of the recooling
function OREC is recommended.
In case of active system cooling
the display (fl ashing). Due to the cooling func-
tion the solar system can be kept operable for
a longer period on hot summer days. A thermal
release of the collector and the heat transfer
medium is ensured as well.
