1. VITALITY Large Splits
Johnson Controls PowerPoint Guidelines | July 21, 2009

2. Large Splits Axial Condensing fan 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

3. Large Splits Centrifugal Condensing fan 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
Indoor can be installed on top of the outdoor unit (compact solution)
Where to apply / typical market:
As an universal condensing unit to match with other systems (evaporator of a AHU)
Indoor Installations in technical room (to prevent from extreme outdoor temps or to install low noise kits or no outdoor inst possible)
For office buildings, supermarkets …

19. Large Splits
Indoor unit VIR
Hot water coil
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
Jumper S2 give priority heat stages: - jumper OFF: Heat pump compressors 1st and 2nd heat stage
- jumper ON: Hot water coil 1st heat stage
