1. INTRODUCTION
The
IATC
(Intelligent Air Technology Control) can manage rooftop air-conditioning unit with:
²
Two circuits comprising one or two compressors
²
Main blower
²
One return fan
²
Economizer: 2 or 3 dampers
²
Electrial heaters (2 stages)
²
Heating valve (hot water coil)
²
2-stage or modulating gas burner
²
Heat recovery FRECO
²
Recovery of thermodynamic heat TRECO
The
IATC
can regulate from temperature, humidity or air quality setpoints.
Passive energy economizers:
²
Summer freecooling
²
Winter freecooling
²
Winter freeheating
²
RECO: recovery of energy from air extracted from the building on external finned coils
²
FRECO: recovery of energy from the condensers of supermarket food refrigeration systems
Active energy economizers:
²
TRECO: recover of thermodynamic energy between the air extracted from the building and fresh air
The
IATC
manages the rooftop unit’s main alarms: antifreeze, generic interlocks, clogged filters and all
refrigerant circuit alarms, such as: compressor thermal overload, high and low pressure switch.
POWER SUPPLY MUST BE
SWITCHED OFF BEFORE STARTING
TO WORK IN THE ELECTRIC
CONTROL BOX
