Control
All of the required controls are grouped together and
wired on the SYSAER R32, factory tested and shipped
READY TO USE.
The controls are located in a sealed compartment that
is isolated from the air ow. The cables and inside
wires are marked in order to facilitate troubleshooting.
The electrical equipment is compliant with EC
standards and EN60204-1.
A single main switch that can be locked can be
accessed from the outside of the SYSAER R32 without
opening the caisson. This switch is sized in the factory
according to all of the options supplied.
The unit comes standard with a single electrical
connection.
A factory-programmed direct digital control (the IATC)
handles and optimizes the operation all throughout
the year, emphasizing comfort and the saving of
energy.
The IATC regulates the heating and the cooling
according to the desired ambient temperature and
also the humidity in cooling mode according to the
setpoint, controlling the cyclical operation and the
rotation of the compressors, as well as the de-icing,
leak gas, high and low pressures, compliance with
the requirements for minimum ventilation and the
continuous fan mode.
Compensation for the summer-winter ambient
temperature and cooling setpoint always above
heating setpoint are provided as standard.
Maintenance parameters and operating times for the
compressors/electrical heaters/unit are also available.
The IATC is equipped with clock card for scheduler
programming. This card can be programmed on site
in comfort-economy modes with a reduction in the
ambient temperature and in the ambient humidity.
The user interface also contains a backlit semi-
graphic liquid crystal display screen with 8 lines and
22 columns. This display shows the current values,
setpoints, operating times and alarms.
It has a 6-key keyboard allowing for on-site
programming of the setpoints, proportional and
integral parameters and the hysteresis thresholds.
The semi-graphic terminal is connected to the
controller using the 150-cm telephone cable provided,
connecting the rear of the terminal to the J10 plug of
the controller.
For other applications, you can increase the distance
between the terminal and the controller:
² Up to 50 m with 6-wire shielded telephone
cable.
² Up to 500 m with 6-wire shielded telephone
cable and two communication cards (optional)
A system for building management provided by
another supplier can communicate via ModBus on
the user interface. The parameters of the SYSAER
R32 are then transmitted and can be modied from a
remote monitoring and troubleshooting station.
