Operation and function
Collector cooling
OCX
Collector cooling option
Adjustment range: OFF / ON
Factory setting: OFF
CMX
Collector maximum temperature
Adjustment range: 70 … 160 °C
Factory setting: 110 °C
The collector cooling function keeps the collector temperature within the operat-
ing range by heating the store. If the store temperature reaches 95 °C the function
will switch off for safety reasons.
If the store temperature exceeds the adjusted maximum store temperature, the
solar system is switched off. If the collector temperature increases to the adjusted
maximum collector temperature, the solar pump is activated until the collector
temperature falls below the maximum collector temperature. The store tempera-
ture may then exceed the maximum temperature, but only up to 95°C (emergency
shutdown of the store).
If the collector cooling function is active,
and

Note:
The cooling function will not become active as long as solar loading is
possible.
Minimum collector limitation
OCN
Collector minimum limitation option
Adjustment range: OFF / ON
Factory setting: OFF
CMN
Minimum collector temperature
Adjustment range: 10.0 … 90.0 °C
Factory setting: 10 .0 °C
If the collector minimum limitation option is activated, the pump (R1) will only
be switched on if the adjustable collector minimum temperature is exceeded. The
minimum temperature prevents the pump from being switched on too often at low
collector temperatures. A hysteresis of 5 K is set for this function.
If the collector minimum limitation is active,

Note:
If
OCF
is active, the collector minimum limitation will be overridden. In
that case, the collector temperature may fall below
CMN
.
Antifreeze function
OCF
Antifreeze option
Adjustment range: OFF / ON
Factory setting: OFF
CFR
Antifreeze temperature
Adjustment range: -40.0 … + 10.0 °C
Factory setting:
+ 4.0 °C
The antifreeze function activates the loading circuit between the collector and the
store when the temperature falls below the adjusted antifreeze temperature. This

Note:
Since this function uses the limited heat quantity of the store, the anti-
freeze function should only be used in regions with few days of tempera-
tures around the freezing point.
The antifreeze function will be suppressed if the store temperature falls
below +5 °C in order to protect the store from frost damage.
