The Flow rate monitoring function can be used to detect malfunctions that
impede the fl ow rate and to switch off the corresponding relay. This will prevent
system damage, e. g. through a dry run of the pump.
If the fl ow rate monitoring function is activated, an error message will appear when
no fl ow rate is detected at the allocated fl owmeter after the delay time has elapsed.
• If a Reference relay has been selected, the fl ow rate monitoring function will
become active when the allocated relay is switched on. In the case of an error,
the complete solar system will be shut down.
• If both a Store and a Reference relay have been selected, the fl ow rate mon-
itoring function will become active when the allocated relay is switched on. In
the case of an error, the allocated store will be blocked until the error message
has been acknowledged. The next store free for loading will be loaded instead.
The error message will appear both in the Status / Messages menu and in the
Status / Solar / Flow rate mon. menu. It can be acknowledged in the Status / So-
lar / Flow rate mon. menu. When the error message is acknowledged, the control-
ler runs a test during which it will energise the relay and again monitor the fl ow rate.

Note:
The pressure monitoring function will only be available when an RPD type

is connected.
The Pressure monitoring function can be used for detecting overpressure or
low pressure conditions inside the system, and if necessary to shut down the af-
fected system components in order to avoid system damage.
overpressure
If the system pressure exceeds the adjustable switch-on value on, an error mes-
sage will appear.
If the Shutdown option has been activated for the overpressure monitoring func-
tion, the solar system will be shut down as well in the case of a fault condition.
When the pressure reaches or falls below the adjustable switch-off value Off, the
system is switched on again.
