Standard functioning
Summer operation with condensing control FI10 (as per standard in S version)
Summer operation with condensing control FI15 (as per standard in SS version)
Functioning with partialised cooling capacity
Winter mode with FI10 or FI15 condensation control (FI10 standard in version S and FI15 standard in version SS)
In summer mode:
Maximum water inlet temperature 23°C.
○
Minimun water pressure 0,5 Barg.
○
Maximum water pressure: 10 Barg / 6 Barg with ASP
○
Maximum water pressure 10 Barg (with P/DP accessory).
○
Maximum water pressure 6 Barg (with ASP/ASDP accessory).
Permitted temperature differentials through the heat exchangers
○ Temperature differential at the evaporator AT = 3 ÷ 8°C with all compressors on) for machines with a "Standard" set-up. The maximum and minimum
temperature differential for the Pump and Tank&Pump machines is related to the performance of the pumps that must always be verified via HITECSA
software.
For t(°C), < 5°C (accessorio BT) it is COMPULSORY to specify the unit's operating temperature when placing the order (evaporator glycol water
inlet/outlet) in order to allow for its correct parametrisation. Condensing control FI10 or FI15, where not already carried out as standard, is also
compulsory. Use of antifreeze solutions: see "Use of anti-freeze solutions"
