In order for the regulator to calculate the quantity of heat produced by
the installation (parameter kWh), input parameter Fx. The parameter
Fx is equal to the flow in litres per minute in the solar circuit.
Determine the value Fx using the following tables, according to the
configuration of the installation and the number or surface area of the
collectors. When the flow is input incorrectly, the display kWh will also
be incorrect.

The quantity of heat (kWh value) can only be used for checks
carried out for personal reasons.

` Tubular solar panels
„ Adjustment parameter MM - Operating mode
Adjustment range: 0 ... 4
Factory setting: 4
For inspection and maintenance work, it is possible to operate the
regulator in manual mode. To operate the regulator in manual mode,
it is necessary to input parameter MM from the following table.
