Extension of the charging pause due to temperature increase in the collector
For precise setting of the charging priorities for systems with multiple storage tanks, the necessary
temperature increase of the collector at which the interruption of the charging into the lower-priority storage
tank is extended by one minute is set here. The interruption is extended because the temperature increase
of the collector is expected to enable charging in the higher-priority storage tank soon.
As soon as ∆T conditions are met, the priority storage tank is charged. If the rise in temperature falls below
the set value, then the charging of the lower-priority storage tank is enabled again.

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 for 1 minute at the collector, the pump is switched off and stays off. The pump is
activated again when the temperature drops below “SProt TOff”.
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 storage” is exceeded in the storage
or pool.
Danger
Danger
When collector protection is active, and both storage and pool are present, the storage is
heated up to „CP Storage S(x) Max“ beyond Tmax S2 (see „4.2. - Tmax S (X)“ on page 22)
which can result in scalding and system damage. When only a pool is used, the pool is not
used for collector protection.
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.
