VITALITYLarge Splits
2
Benefits:
Split system from 20 to 90 kW
Ductable indoor unit
Auxiliar heating (elect heater or hot water coil) available
Allows ventilation, free cooling available
Where to apply / typical market:
As an universal condensing unit to match with other systems (evaporator of a AHU)
For offices where duct installation is the preferred solution against chiller+FCU or multiple minisplits
Typical installations are anyplace where AHU is fitted, industry, petrol stations

Compressor Soft Start: It is only needed to do the wiring connections. It
comes automatically adjusted from factory to the optimal point
Provides alarm signal in case of:
- Wrong phase sequence- Low voltage- Frequency out of range- Locked rotor- overheating…

• Jumper S2 give priority heat stages:- jumper OFF: Heat pump compressors 1st and 2nd heat
stage
- jumper ON: Hot water coil 1st heat stage
• Modulating valve with 4 stages:- Stage 1: Supply air 30°C- Stage 2: Supply air 40°C- Stage 3: Supply air 45°C- Stage 4: Supply air 50°C
& Hot water coil minimum supply air temperature 15°C
• Anti freeze protection:- If water temperature < 3°C, water pump and water valve are activated open- Antifreeze protection stop when water > 6°C
• Hot water coil
