3.15 Adjustment parameter FT - Tubular solar collector function
Range of adjustment: 0/1
Factory setting: 0
0: no
1: yes
3.16 Adjustment parameter FX - Maximum flow rate
Range of adjustment: 0 ... 20
Factory setting: 9.5
The regulator calculates the approximate amount of heat transferred. To do
so, the regulator must know the system's maximum flow rate at full load. If
the flow rate used is incorrect, the results obtained will also be incorrect.
The power rating results are only to be used for personal checks. Among
other devices, they are used as a means of checking functions. For the
regulator to calculate the amount of heat, it has to know the maximum flow
rate in l/min vor the secondary circuit.
3.17 Adjustment parameter MM - Operating mode
Range of adjustment: 0 ... 8
Factory setting: 8
For inspection and maintenance work, it is possible to operate the regulator
in manual mode. To do so, simply set parameter MM in accordance with the
following pattern.
In operating modes MM 0 to MM 7, the LED flashes red/green. In automatic
regulation mode MM 8, the LED lights up red or green (depending on
conditions).

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 tank 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.
The following table shows the maximum flow rate according to the number of
collectors..
