Application Guide /FLEXAIR-AGU-1505-E
Our FLEXAIR range includes our New e-climatic control
generation.The main features of this control are :
- Plastic cover to protect the circuit board from water entry
and humidity and with all the different connection terminals
correctly identi
fi ed.
- Two independent buses, one for display and sensors connec-
tion and another one for internal components.
- Possibility of storing all parameterized conditions before an
alarm is produced.
- Stronger hardware thanks to the plastic cover which protects
the circuit board from water entry and humidity (and at the
same time clearly identify all the different connection termi-
nals)
- More reliable hardware thanks to the different communi-
cation buses for internal/main devices (compressors, fans,
etc.) and for the remote/accessory ones (display, probes),
which preserve the regular unit operation even in case of
commissioning miswirings
- Enhanced ClimaticTM regulation thanks to the better em-
bedded processor and to the new Universal I/O chip, which
allows to match better contacts, probes and relays to the
controller board.
- Internal log memory to record unit operating trends (e.g.
temperatures before alarm occurrence).
OPTIMIZED OPERATION AND SETUP
SAVES ENERGY
eClimatic is designed to provide the best ef fi ciency throughout
unit’s lifecycle while ensuring reliable and consistent operation
with user-friendly interfaces .This controller monitories more
machine parameters than ever to improve energy ef
fi ciency
and reliability
1 Indoor air temperature (humidity and CO2 levels as an option )
2 Outdoor air temperature (outdoor humidity as an option )
3 Return and supply air temperature
4 Filter pressure drop
5 Air fl ow rate with eFlow
6 Refrigerant pressures, temperatures & compressor monitoring
7 Power energy metering (option )
Three different platforms are available :
● End customer display DC: with basic con fi gurations, set
points, main temperature readings and alarms.
● Multiple display DM: graphic customer display with basic
con fi guration of the end customer display plus schedule
programming and set of fresh air %.
● Service display DS: Specially focused to maint
Refrigeration circuit ef fi ciency management
Climatic control regulation
The Climatic controls the blowing air temperature to achieve the
customer comfort in the most ef
fi cient way, matching perfetctly
the cooling/heating load with the optimum unit capacity staging
(multiscroll compressors, heat recovery modules, freecooling,
gas burners, water coils, etc.).
The unit reliability is ensured by a complete set of protections as
compressor envelop control, air-
fl ow and pressure drops check,
advanced refrigerant leakage detection, compressor anti short
cycling rules.
All these fetaures are designed to optimize the unit performance,
but at the same time to increase its life-time and make easier
its maintenance.
Dynamic defrost:
It is a standard feature of all Lennox heat pumps. It limits the
number and the duration of the defrost cycles in winter to maximize
COP. With a smart and propietary frost-detection system, the
lennox rooftops autumatically optimize the number and the
durantion of the defrost cycles to get the best units perfonces
in every enviromental conditions.
