„ Adjustment parameter FT - Tubular solar collector
function
Adjustment range: 0/1
Factory setting: 0
0: no
1: yes
If the regulator detects a temperature rise in the collector of 2 K
compared to the last measurement, the solar pump runs at full speed
for 30 seconds to measure the current average temperature.
The measured temperature thus becomes the new reference
temperature.
If the measured temperature (new reference) then increases again
by 2 K, the solar pump starts again for 30 seconds.
The regulator switches automatically to solar heating mode if the
temperature difference between the collector and the calorifer
exceeds the switching-on temperature difference when the solar
pump is operating or the system is stopped.
If the collector temperature falls by 2 K while the system is stopped,
the tubular solar collector activation temperature is rechecked.

Adjustment parameter Fx - Maximum flow rate
Adjustment range: 0 ... 20 l/min
Factory setting: 6.7
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.

Adjustment parameter MM - Operating mode
Adjustment range: 0 ... 2
Factory setting: 2
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.
