4.1.11 Limit collector temperature
Collector emergency shutdown
If the adjusted collector temperature limit (
EM
/
EM1 / EM2 ) is exceeded, the solar pump (R1/R2) is
deactivated in order to avoid a damaging overheat-
ing of the solar components (collector emergency
shutdown). The factorysetting for the limit tem-
perature is 140°C, but it can be changed within the
adjustment range of 110 ... 200°C.
is displayed
(flashing).
4.1.12 System cooling
If the adjusted maximum store temperature is
reached, the solar system switches-off. If now the
collector temperature rises to the adjusted maxi-
mum 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 temperature), 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 is shown on
the display (flashing). Due to the cooling function
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.
4.1.13 Option minimum collector limitation
The minimum collector temperature is a minimum
switch-on temperature, which has to be exceeded
so that the solar pump (R1/R2) is switched-on. The
minimum temperature is meant to avoid a steady
starting-up of the solar pump (or solid fuel boiler
charging pumps) for low collector temperatures. If
the minimum temperature is underrun,
is shown
on the display (flashing).
