Maximum tank temperature (emergency cut-off): Non-adjustable value
80 °C
If the maximum tank temperature is exceeded, tank heating is interrupted to
prevent damage due to overheating. The display shows
(flashing) and the LED changes to flashing red/green.
If the temperature in the collector rises above its maximum temperature CX
even though the solar circuit is stopped (maximum storage temperature
reached), the solar pump (R1) switches on and cools the collector by means
of the pipes and the tank (system cooling). It is perfectly natural for the tank
temperature to increase, but it must not exceed 80 °C (safety system).
The cooling functions allows heat to dissipate; the system thus remains
operational longer during hot summers. When it leaves the factory, the
collector's maximum temperature is preset to 120 °C; however, it is possible
to change this within the range 100 ... 125 °C. If the maximum collector
temperature is exceeded, the display shows
and the LED changes to flashing red/green.
When the solar collector reaches a minimum temperature of 30 °C and a
preset temperature difference of 10 K from the tank temperature, the
regulator switches on the solar circulating pump at full speed for the time
period set by parameter tu. During this phase, any air bubbles present in the
solar collectors or the pipes are moved to the complete solar station by the
high circulation speed in the pipes and eliminated by the Airstop system
(manual bleed degasser). After this phase, the regulator changes to
"matched flow" mode. The remaining self-calibration time is displayed with
parameter tc.
Adjustment parameter N1 sets a minimum value for the solar pump speed
factor (primary circuit) at the relay R1 output.
Adjustment parameter N2 sets a minimum value for the secondary circuit
pump speed factor primary circuit at the relay R2 output..
