Frost protection:
As soon as 4 °C are reached at the collector, the frost
protection function operates the loading circuit between
collector and 1st store in order to protect the medium in
the loading circuit against freezing or coagulation.
If the collector temperature exceeds 5 °C, this function is
switched-off.
If the 1st store is blocked in the system, this function ids
suspended.
The pump output is controlled with relative maximum pump
speed (provided that the function is activated).
2-collector systems: Only that circuit is operated, which complies with the abo-
ve-mentioned switch-on conditions.
Chimney sweeper:
By means of this function, the respective store can be „re-
moved“ from the solar regulation, that means that it is no
longer considered for solar charge. The temperature of the
store is furthermore indicated but a sensor defect is no
longer signalised.
St2on ... St4off:
This function is used for activating a fixed relay condition if
it is required. Because of that e.g. in case of flue gas measu-
rement made by the chimney sweeper, the relays required
for activation of the boiler can be switched-on. The required
relay status is adjusted in the chimney sweeper menu (Ex-
pert/Chimney sweeper).
2-collector systems:
2 separate collector circuits (2 pumps):
Only that collector circuit, which needs to be cooled, is ope-
rated. If one store is charged right now by another collector,
this charge is continued.
common collector circuits (1 pump): The „pump speed“ of the pump acts upon collector cooling.
A parallely operating store charge by the 2nd collector is
subordinated.
Collector cooling function:
The collector cooling function starts if the adjusted maxi-
mum collector temperature is reached. If this temperature
is underrun by 5 K, this function is switched-off.
The collector is cooled by the heat dissipation to the next
free store, that means to a store which is not blocked. The
numerically last store is not considered (swimming pool
protection).
The pump output is controlled with relative maximum pump
speed (provided that it is activated).
Note: it is not possible to adjust the maximum collector
temperature (Tcolmax) higher than the collector security
switch-off temperature.
Tcolmax:
Adjustment range 80 ... 160 °C
Factory setting 110 °C
Hysteresis 5 K
