Thus, the heating circuit return temperature increases by the DTSet value. The adjustable
maximum boiler return temperature limits the mixing temperature. If the store temperature falls
below the heating circuit return temperature by the switch-off temperature difference, the mixer
will close.
The runtime defines the time needed for the mixer to switch from its initial position to the end
position. The Detection parameter determines the opening angle of the mixer when the heat-
ing circuit is to be checked for activity. The Time defines the point in time at which the mixer is
completely closed for adjustment every 24 hours.

2: Sen. store Heating circuit internal
3: Sen. boiler ret.
If Internal is selected in the HC parameter, the RMS function will only become active when
the selected heating circuit of the controller is active, too. For this purpose, the heating circuit
selected has to be controlled by the controller or by a module connected.

This function can be used to detect malfunctions that impede the flow rate and to switch off the
corresponding output. This will prevent system damage, e.g. through a dry run of the pump.
If the flow rate monitoring function is activated, an error message will appear when no flow rate
is detected at the allocated flow rate sensor after the delay time has elapsed.
If a reference relay has been selected, the flow rate monitoring function will become active
when the allocated relay switches on. In case of an error, the complete solar system will be shut
down.
The error message will appear both in the Status / Messages menu and in the Status /
Arrangement / Flow rate mon. menu. It can be acknowledged in the Status / Arrange-
ment / Flow rate mon. menu only.
