From firmware version REG 4.30, it is possible to find a new function for managing dehumidifiers if the zone is in Economy mode:
By entering the Zone page and then in Configuration Zone / 3, a new column appears that shows 4 options for each zone:
AS Comfort: if selected, the behaviour of the associated dehumidifier remains the same of the previous firmware, therefore the humidity set point that activates or not the dehumidifier is the one reported in the Zone Parameters, whether the zone i sin Economy or Comfort. This option is the default one to ensure firmware backward compatibility;
Disabled (Exc. Dew Point): if the dehumidifier is selected and the zone is in Economy mode, the dehumidifier will always be deactivated, unless the zone is at risk of condensation (Dew Point), in that case the dehumidifier starts up until the alarm goes off, then it switches off:
SET RH Economy: if this option is selected the humidity set point, if the zone is in Economy mode, can be set it in Configuration 1, where the dedicated parameter (Eco HR dedicated Set) can be found; if the zone is in Comfort mode, the humidity set point remains the same as the one in Zone / Zone Parameters
Warning
This Economy humidity set point applies to all the zones and must be set higher than the humidity set points of the zone to which a dehumidifier is linked.
Always Disable: in this case if the zone is in Economy mode the dehumidifier will never start, even if the zone is at risk of condensation.
