    (SET_ES), higher than the standard one, will be used. The parameter HES defines the energy setpoint 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.
