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

Main Advantages & Features Vs SOC/SOH + SICH

R410A Refrigerant

Improved efficiency

Quiet operation

Shares same indoor unit as VCH -> VIR

Long pipe run (up to 50m)

New size 20 kW

New PCB YKN2Open (JCI protocol)

New options and accessories

Soft Start Compressor for outdoor unit

LAK as option (before as standard)

Outdoor Fan: High efficiency, Low noise operation condenser fan.

Johnson Controls


16

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…

Economizer can be assembled alone with the unit

Return fan needs to be ordered always with return fan

• Economizer & return fan

Johnson Controls


• 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
