REGULATION ALGORITHM IN HEATING MODE WITH SUPPLEMENTARY AUTOMATICALLY ADJUSTING
ELECTRIC HEATERS
In models with INTEGRATED AND AUTOMATICALLY ADJUSTING electric heaters, heating components are determined by
the temperature read by the water probe as well as always being subject to the consents programmed for this sensor.
With this configuration, the automatic change-over always takes place at the air probe temperature (Dead Zone). Setting
depends on water temperature, as shown in the following three examples:
N.B.: There is a fixed hysteresis of1°C between temperatures of 15°C and 30°C to prevent constant flucturations
between A and B and between B and C.
For example, for rising temperatures, the switch from A to B takes place at 15.5°C whilst for falling temperatures,
the switch from B to A takes place at 14.5°C. The same happens at the 30°C threshold (real thresholds of 29.5
and 30.5°C).
