„ Adjustment parameter DT - Reference
temperature difference
Adjustment range: 10 ... 20 K
Factory setting: 20 K

Switching-on difference: Non-adjustable value 10 K
Switching-off difference: Non-adjustable value 5 K
The regulator reads the temperatures measured by sensors S1 (TC)
and S2 (TS) and compares the resulting temperature difference with
the switching-on difference which is preset to 10 K. Regulation is
activated when the temperature difference
∆T is equal to or greater
than the preset value. The display shows . The LED changes to
green. When the value falls below the preset 5 K switching-off
difference, the regulator switches off. The regulator tries to achieve a
temperature difference of 20 K (factory setting) between the collector
and the tank to produce high temperature hot water as rapidly as
possible. To do this, it uses dynamic speed control.
„ Adjustment parameter SX - Set temperature of the
solar calorifier
Adjustment range: 20 ... 80 °C
Factory setting: 60 °C
 Maximum tank temperature (emergency cut-off): Non-
adjustable value 80 °C
The set temperature Sx is the desired temperature for the solar
calorifier.
If the maximum tank temperature is exceeded, tank heating is
interrupted to prevent damage due to overheating. The display
shows
and (flashing) and the LED changes to flashing red/
green.
The higher the set temperature for the calorifier, the greater the
energy stored. Setting to 60 ... 75°C is suitable for normal use with
daily draw-offs.
In the event of prolonged absences (weekend, holidays):
- Reduce the calorifier temperature to 50°C
- Turn off the back-up (boiler or electrical resistance)
The installation is thus protected against overheating and the
longevity of the heat conducting fluid is conserved.
