The controller is equipped with an independent
tempe rature differential regulation for which
minimum and maximum temperature limations
as well as corresponding switch-on and -off
temperatures can be separately adjusted. Only
possible for Arr = 2 and 8 (e.g. for solid fuel
boilers or heat exchange regulation).
Is the adjusted value MX3O exceeded, the relay
2 will be deactivated. By falling below MX3F,
the relay will be switched on again.
When the adjusted value falls below MN3O, the
relay will be deactivated. By exceeding parame-
ter MN3F, the relay will be activated again. Par-
allely, 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 over-
heating of the solar components (collector emer-
gency shutdown). The factory setting for the lim-
it temperature is 130 °C, but it can be changed
within the adjustment range of 110 ... 200 °C.
is displayed (flashing).
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 temper-
ature), but only up to 95 °C (emergency shut-
down of the store). In order to recool the store
to its maximum temperature, the use of the re-
cooling function OREC is recommended.
In case of active system cooling
the display (flashing). Due to the cooling func-
tion the solar system can be kept operable for
a longer period on hot summer days. A ther-
mal release of the collector and the heat transfer
medium is ensured as well.
