If the adjusted collector emergency shutdown temperature
(NOT / NOT1 / NOT2) is exceeded, the controller will
switch off the solar pump (R1 / R2) in order to protect the
system against overheating (collector emergency shutdown).
The factoring setting is 140 °C but it can be changed within
the adjustment range of 110 ... 200 °C. If the temperature is
exceeded, (flashing) is shown on the display.
When the adjusted maximum store temperature is reached,
the system stagnates. If the collector temperature increases
to the adjusted maximum collector temperature (CMX
/ CMX1 / CMX2) the solar pump is activated until the
collector temperature falls below the maximum collector
temperature. The store temperature may increase (sub-
ordinate active maximum store temperature), but only up
to 95 °C (emergency shutdown of the store). If the store
temperature is higher than the maximum store temperature
(S MX / S1MX / S2MX) and if the collector temperature
is at least 5 K below the store temperature, the solar system
remains activated until the store is cooled down below the
adjusted maximum temperature (S MX / S1MX / S2MX)
via the collector and the pipework (only if the OREC
function is activated).
If the system cooling function is enabled,
shown on the display. Due to the cooling function, the sys-
tem will have a longer operation time on hot summer days
and guarantees thermal relief of the collector field and the
heat transfer fluid.
The minimum collector temperature is the minimum tem-
perature which must be exceeded for the solar pump (R1
/ R2) to switch on. The minimum temperature prevents the
pump from being switched on too often at low collector
temperatures. If the temperature falls below the minimum
temperature, (flashing) is shown on the display.
The antifreeze function activates the loading circuit between
the collector and the store when the temperature falls be-
low the adjusted antifreeze temperature. This will protect
the fluid against freezing or coagulating. If the adjusted anti-
freeze temperature is exceeded by 1 °C, the loading circuit
will be deactivated.
Note
Since this function uses the limited heat quantity
of the store, the antifreeze function should be
used in regions with few days of temperatures
around the freezing point.
