 after the FS11 delay from the 4-way valve switching, the domestic hot water valve 1 is
switched on
 after the FS10 delay the domestic hot water valve 2 is switched off
Once the domestic hot water set-point is reached:
 the domestic hot water valve 2 is switched on
 after the FS10 delay domestic hot water valve 1 is switched off
 after FS28 seconds the domestic hot water circulation pump and the compressors are
switched off
 after the dF08/2 delay the status of the 4-way valve is reversed
If the domestic hot water production is working and the temperature detected by the chiller
regulation probe is greater than ST01+ST07 (cold water required), the sequence of operatiuon is
the following:
 the domestic hot water pump will remain on
 the domestic hot water valve 2 is switched on
 after the FS10 delay the domestic hot water valve 1 is switched off
 the compressors are switched off
 after the DF08/2 delay the 4-way valve status is reversed
 after a delay of dF08/2 the compressors are switched on to produce chilled water and
domestic hot water
When the domestic hot water set-point is reached:
 domestic hot water valve 2 is switched on
 after the FS10 delay the domestic hot water valve 1 is switched off
 after a delay of FS28 seconds the domestic hot water circulation pump is switched off
b) None of the compressors are switched on for the production of chilled water
In this case, the cycle is reversed as follows:
 the 4-way valve status is reversed
 after dF07/2 the compressors are switched on
 the domestic hot water pump switches on after the FS11 delay from start-up of the compressors
 after a delay of FS27 seconds the domestic hot water valve 1 is switched on
 after the FS10 delay the domestic hot water valve 2 is switched off.
Once the domestic hot water set-point is reached, the sequence of operation is the following:
 the domestic hot water valve 2 is switched on
 after the FS10 delay the domestic hot water valve 1 and the compressors are switched off
 after a delay of FS28 seconds the domestic hot water circulation pump is switched off
 after the DF07/2 delay the 4-way valve status is reversed and normal regulation is
restored.
If chilled water is required during the production of domestic hot water, operation is the same as in
the previous case.
39. SOLAR PANEL MANAGEMENT
Though appropriate configuration of FS55 and FS56 parameters is possible to use the solar panel in heating
or for domestic hot water production.
The solar panel is managed through the valve and water pump control; their status depend from:
 solar panel temperature
 regulation probe (typically heating regulation probe or domestic hot water regulation probe); this
probe is defined in FS57 and FS58 parameters
39.1 SOLAR PANEL IN DOMESTIC HOT WATER
 Compressors and solar panel in integration to domestic hot water (FS55=1):
If:
solar panel temperature – domestic hot water temperature > FS59 (Dt to enable solar panel in
domestic hot water)
the solar panel are enabled to work; domestic hot water probe is defined by FS57 parameter (it is possible to
set another probe, if needed).
