Collector cooling function:
Solar/Options/col. cooling
selection: „Yes“, „No“
factory setting: „No“
if you select „Yes“:
Solar/adj. values/Tcolmax
adjustment range: 80 … 160 °C
factory setting:: 110 °C
hysteresis 5 K
The collector cooling function starts, when the adjusted
maximum collector temperature is reached. If this tem-
perature is underrun by 5 K, this function is switched off.
The collector is cooled via the heat transfer to the next
free store (a store which is not blocked). The numerically
last store is not used (swimming pool protection or in the
case of multi-store systems).
The pump output (provided that the function is active) is
controlled with maximum relative pump speed.
Note:
It is not possible to adjust a temperture value for the maxi-
mum collector temperature (Tcolmax) which is higher than
the collector emergency shutdown temperature. There
must be a difference between these two temperatures of
at least 10 K.
2-collector systems:
2 separated collector circuits (2 pumps):
The collector circuit which needs to be cooled is operated.
If one store is being loaded by another collector, this load-
ing is continued.
shared collector circuit (1 pump): “Pump speed“ depends on collector cooling which takes
priority.
Recooling:
Solar/Options/recooling
selection: „Yes“, „No“
factory setting: „No“
This function is used for keeping the system temperatures
and consequently the thermal load as low as possible.
If the temperatures of all stores of the system have ex-
ceeded the maximum temperature, the Tstmax for the rst
store is temporarily overidden to reduce the surplus ener-
gy via the pipework and the collector. Note Tstmax may be
exceeded so additional scald protection may be required.
This “circulation“ is switched-off once the maximum store
temperature is underrun by 2 K.
2-collector systems:
Both collector circuits are activated in a 2-collector sys-
tem.
Combination with collector cooling function:
If the option “collector cooling“ is activated in addition to
the recooling function, the behaviour of the recooling func-
tion changes.
The objective is now to dissipate the energy supplied by
collector cooling.
If the temperature at the collector decreases by 5 K below
that of the store, the recooling function becomes active
and the loading circuit is again operated to cool the store.
If the difference between collector and store decreas-
es below 3 K during that cooling period, the function is
switched-off.
2-collector system:
In a 2-collector system, the collectors are operated separa
tely, using the switch-on conditions described above.
