Determining the flow rate for the connected solar
circuit pumps
NOTE
The following settings are only possible with the flow rate determina-
tion method "Without flow sensor".
Flow rate determination method set to "Without flow sensor".
✓
: press button.

The display for setting the min/max flow rate appears.

SET: press button.

The "max" value flashes in the display and the pump begins to

run at maximum speed.
The flow rate value must now be read at the pump assembly's flow

rate display.
: enter the flow rate value.

SET: press button to confirm.

The "min" value flashes in the display and the pump begins to

run at minimum speed.
The flow rate value must now be read at the pump assembly's flow

rate display.
: enter the flow rate value.

SET: press button to confirm.

NOTE
• If other solar circuit pumps (e.g. east/west roof system) are con-
nected to the controller, the flow rate for these pumps must be
determined and entered as described here.
• If the minimum pump speed in the "Parameters" menu, or the pump
level at the pump, is changed at a later point in time, the flow rate
must be determined and set once more for more precise calculation
of the heat quantity.
• If the collector is in a stagnant state, pump starts are blocked in
order to prevent damage. A corresponding information window is
displayed.
7.3.7 Thermostat function
This function allows a controller output to be controlled depending on a
pre-defined temperature range. Depending on the temperature setting,
the thermostat function can be activated either when the temperature
falls below (heating) or rises above (cooling) a certain level.
If "on" value is higher than "off" value: If the temperature difference
exceeds the defined "on" value, the output is switched on until the tem-
perature difference falls below the "off" value.
If "on" value is lower than "off" value: If the temperature falls below
the defined "on" value, the output is switched on until the temperature
rises above the "off" value.
It is also possible to limit the thermostat to specific times.
