NOTES:
- “r.o.” stands for read only values
- Default factory settings here indicated are valid for XRB77CH and XRB70CH only
- Some parameters could not be present in other versions (for example XRB30CH) due to platform
specific limitations
- RTC parameters are present only in models equipped with RTC option.
9. REGULATION
The regulation is based on the temperature measured
by the thermostat probe (P1) with a positive differential
compared to the set point: if the temperature increases
and reaches the set point plus differential, the
compressor will start. The compressor will stop when
the temperature reaches the set point value again. In
case of fault because of the thermostat probe, the start
and stop of the compressor are timed through
parameters CoF and Con.
10. ENERGY SAVING ALGORITHMS
The device permits to set different temperature to be used during normal and reduced power use. The
standard SET-POINT (SET) is used to maintain the temperature at a certain value when the energy saving
status (ES) is not active. On the other side, when the ES status is active a different SET-POINT (SET_ES),
higher than the standard one, will be used. The parameter HES will have to be set to change the regulation
temperature according to the following formula: SET_ES = SET + HES
There are also two different differential values for SET and SET_ES, which are used for compressor cut-in
and cut-out: when ES status is active the HYE parameter will be used instead of the HY parameter.
