-MANAGEMENT OF COMPRESSORS
After the compressor has been turned ON, it must go on working for at least 1 min
(default) (VALUE SELECTABLE THROUGH DEDICATED MASK).
After the compressor has been turned OFF, it is necessary to wait for at least 6 min
(default) before restarting it (VALUE SELECTABLE THROUGH DEDICATED
MASK).
The second compressor can not be turned ON before 3 min. have elapsed from the
starting up of the first one (default) (VALUE SELECTABLE THROUGH
DEDICATED MASK).
In the 2-compressor configuration it is possible to select the compressor
ROTATION option.
The HIGH-LIMIT step activates during dehumidification as follows:
- if within one minute from the indication of higher limit of the cooling differential
(85%) the temperature value is not comprised within the regulation differential
(85% -15%), the HIGH-LIMIT step is activated and dehumidification stopped.
- the step remains active until 15% of the heating differential is reached, then
dehumidification will restart only if required.
-ENERGY SAVING
In order to adopt the Energy Saving option check that:
Ambient Temperature - Water Temperature > (SET energy saving + HYST energy
saving)
The value of SET ENERGY SAVING can be selected through a dedicated mask
(mask GTEMPES in the "Temperature Management" branch).
If this condition occurs:
- by answering affirmatively to the COM-ES mask ("Compressors compatible with
the valve in the Energy Saving option"), the compressors steps within the
differential will be postponed with respect to the cold water valve, but only when the
conditions necessary to the energy saving activation occur. Otherwise, with
activated energy saving option but functioning conditions, the compressors will be
normally functioning.
- by answering negatively to the COM-ES mask, the compressors steps will be
eliminated and only the valve will remain active in case the conditions necessary to
the energy saving activation occur. Otherwise, the compressors will be normally
functioning.
