5. Protections
Menu “5. - Protections / Protective functions” can be used to activate and set various protective
functions.
The menu is closed by pressing “esc” or selecting “Exit”.
CAUTION
This does not under any circumstances replace the safety facilities to be provided
by the customer!
5.1 SYSTEM PROTECTION
Highest Priority Protection
System protection prevents overheating of system components by automatic shutdown of the solar pump. If “SProt Ton” is exceeded at the collec-
tor, the pump is switched off and stays off. The pump is activated again when the temperature drops below “SProt TOff”.
System protection - Settings range: ON / OFF / Default setting: On
SP T on - Settings range: 60 °C to 150 °C (140 °F to 302 °F) / Default setting: 120 °C (248 °F)
SP T off - Settings range: 50 °C (122 °F) to T on minus 5 °C (23 °C) / Default setting: 115 °C (239 °F)
CAUTION
When system protection is on, the temperature in the idle collector will be very high, thus the pressure in the system will rise and
can damage your system.
Pay close attention to the instructions of the system manufacturer.
5.2 COLLECTOR PROTECTION
Collector protection prevents overheating of the collector. The pump is switched on to transfer heat from the collector to the storage tank.
If “CP Ton” is exceeded at the collector sensor, the pump is switched on until the temperature reaches “CP Toff” or the temperature “CP Tmax stor-
age” is exceeded in the storage.
Collectorprotection - Settings range: On / Off / Default setting: Off
CP T on - Settings range: 60°C to 150°C (140°F to 302°F) / Default setting: 110°C (230°F)
CP T off - Settings range: 50°C (122°F) to T on minus 5°C (23°F) / Default setting: 100°C (212°F)
CP Storage S(x) Max - Settings range: 30°C to 140°C (86°F to 284°F) / Default setting: 90°C (194°F)
DANGER
When collector protection is active, and both storage and pool are present, the storage is heated up to “CP Storage S(x) Max” be-
yond Tmax S2 (see “4.2. - Tmax S (X)” on page 25) which can result in scalding and system damage. When only a pool is used, the
pool is not used for collector protection.
DANGER
System protection has a higher priority than collector protection. Even when the switch on conditions for collector protection are
present, the solar pump will be switched off when SP T on is reached.
