5.3 RECOOLING
In hydraulic systems with solar when the recooling function is activated excess energy from the storage tank is fed back into the collector. This only
takes place if the temperature in the storage tank is higher than the value “Recool Tsetpoint” and the collector is at least 20°C (68°F) cooler than
the storage tank and before the storage tank temperature has dropped below the value “Recool Tsetpoint”. In systems with two storage tanks the
setting applies to both storage tanks.
Recooling - Settings range: On, Off / Default setting: Off
Rückkühl Tsoll - Settings range: 0°C to 99°C (32°F to 210°F) / Default setting: 70°C (158°F)
CAUTION
Energy is lost via the collector when Recooling is active! Recooling should only be active in periods with very little demand for heat
e.g. during longer absence / holidays.
5.4 FREEZE PROTECTION
A two-stage frost protection function can be activated. In stage 1 the controller switches the pump on for 1 minute every hour if the collector tem-
perature drops below the set value “Frost stage 1”. If the collector temperature drops further to the set value “Frost stage 2” the controller switches
the pump on continuously. If the collector temperature then exceeds the value “Frost stage 2” by 2°C, then the pump switches off again.
Frost protection setting range: on, off/default setting: off
Frost stage 1 setting range: from -25°C to 10°C (-13°F to 50°F) or off/default setting: 7°C (44°F)
Frost stage 2 setting range: from -25°C to 8°C (-13°F to 46°F) /default setting: 5°C (41°F)
CAUTION
This function causes energy to be lost via the collector! It is normally not activated for solar systems with antifreeze. Observe the
operating instructions for the other system components!
5.5 SEIZING PROTECTION
If the seizing protection is activated, the controller switches the relay in question and the connected consumer on every day at 12:00 (setting “dai-
ly”) or weekly on Sundays at 12:00 (setting “weekly”) for 5 seconds in order to prevent the pump and/or the valve from sticking after an extended
stationary period.
Setting range R1: daily, weekly, off/default setting: Off
Setting range R2: daily, weekly, off/default setting: Off
Setting range R3: daily, weekly, off/default setting: Off
5.6 COLLECTOR ALARM
If this temperature is exceeded at the collector sensor when the solar pump is on a warning or error message is triggered. A warning message is
shown in the display.
Collector alarm - Settings range: Off, On / Default setting: Off
Collector alarm - Settings range: 60°C to 299°C (140°F to 570°F) / Default setting: 115°C (239°F)
Delay - Settings range: 1 to 60 Minuten / Default setting: 1
