1.3 Description of the unit's main control panel

The main control panel is found on the unit itself and

is protected from the outside by a removable metal

panel.
1 Connection entry.
2 Grommet support tray.
Given that the air conditioning unit is installed on the

roof of a building or property, users must under no

circumstances inspect or adjust the unit themselves.

All of inspections or adjustments that may be made

by the user are performed using the DPC-1 thermo‐

stat.

If the air conditioning unit is faulty, its self-diagnostics

system will identify the source and the pilot light -1-

on the display of the DPC-1 thermostat will switch on.

The display will also show a two-digit number on the

lower  left  -2-,  indicating  the  effected  component.

See 

 Placing the unit out of service due to a fault 

 

, see

on page 10 .
If the thermostat display keeps showing the pilot light

-1- and any fault code or if the air conditioner does not

start,  contact  a  Johnson  Controls  Inc.  Authorised

Technical Assistance Service.

1.4 Modes of operation

The VITALITY range of air conditioning units includes different models: the operating mode for each one

varies depending on the specific model.

1.4.1 VAC models: air conditioning

The VAC model circulates gas refrigerant (R-410A) through a cooling circuit driven by two compressors

(depending on models). The propelled gas circulates through an evaporator coil where it absorbs ambient

heat and evaporates. To liquefy the evaporated gas, it is then circulated through a condenser coil where

it releases the previously absorbed heat into the atmosphere.
To favour the evaporation and condensation of the gas refrigerant, the unit has supply and intake fans

that force the air through each of the coils. In the case of the evaporator, the fan pushes air to the inside

of the building or property through previously-installed distribution ducts. In the case of the condenser,

the fan pushes fresh air through the coil and then sends it back outdoors.
A series of filters remove dust particles and pollen, etc. from the air sent inside the building or property.

1.4.2 VAH models: heat pump

The VAH models operate the same way as the VAC units, although they can also reverse the cooling

circuit operation so that the coils exchange functions and send warm air to the inside of the building or

property and the cold air outdoors.
