When the holiday cooling function is activated, ☼ and ⚠ (ashing) are shown on
the display.
If the holiday cooling function is active, ⓵, ☼ and ⚠ are displayed (ashing).
Note:
The holiday cooling will only become active when the holiday mode is
triggered by means of button
⛁
(see page 12).
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 [50.0 … 190.0 °F]
Factory setting: 10.0 °C [50.0 °F]
If the collector minimum limitation option is activated, the pump (R1) is only
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 [10 °Ra] is set for this function. If the
collector minimum limitation is active, ❄ is displayed (ashing).
Note:
If OSTC or OCF is active, the collector minimum limitation will be over-
ridden. In this case, the collector temperature may fall below CMN.
Antifreeze function
OCF
Antifreeze function option
Adjustment range: OFF / ON
Factory setting: OFF
CFR
Antifreeze temperature
Adjustment range: -40.0 … +10.0 °C [-40.0 … +50.0 °F]
Factory setting: +4.0 °C [+40.0 °F]
The antifreeze function activates the loading circuit between the collector and the
store when the temperature falls below the adjusted antifreeze temperature. This
will protect the uid against freezing or coagulating. If the adjusted antifreeze tem-
perature is exceeded by 1 K [2 °Ra], the loading circuit will be deactivated.
If the antifreeze function is activated, ❄ is displayed. If the antifreeze function is
active, ⓵ and ❄ are displayed (ashing).
Note:
Since this function uses the limited heat quantity of the store, the anti-
freeze function should be used in regions with few days of temperatures
around the freezing point.
The antifreeze function will be suppressed if the store temperature falls
below +5 °C [+40 °F] in order to protect the store from frost damage.
