EDM AER 01 S 2GB
SysAer

Frame
The mounting frame is made from galvanized steel
sheet. It is delivered with a seal to connect the edge
of the frame to the unit and eliminate vibrations and
thermal bridges.
Control
All of the required controls are grouped together and
wired on the SysAER, factory tested and shipped
READY TO USE.
The controls are located in a sealed compartment that
LV LVRODWHG IURP WKH DLU ʿRZ7KH FDEOHV DQG LQVLGH
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 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,
controlling the cyclical operation and the rotation of
the compressors, as well as the de-icing, overload
protection, high and low pressures, compliance with
the requirements for minimum ventilation and the fan
mode, continuous or intermittent.
Compensation for the summer-winter ambient
temperature and a min/max ambient temperature
setting are provided as standard.
Maintenance parameters and operating times for the
compressors/unit are also available.
The
IATC can be equipped (optionally) with clock
card for day-night programming. This card can be
programmed on site in occupied-unoccupied modes
with a reduction in the ambient temperature.
The user interface also contains a backlit semi-
graphic liquid crystal display screen with 4 lines and
20 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 strips and
the alarm thresholds.
The semi-graphic terminal is connected to the
controller using the 80-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 200 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 with
a card of the RS-485 type as an option, on the user
interface. The parameters of the
SysAER are then

monitoring and troubleshooting station.
In case several SysAER are installed (in zones or
groups whether or not different), it is possible to
display the parameters of each unit with only one
interface for the entire installation. The principle
consists in connecting all of the units in parallel,
using a single pLAN bus (proprietary protocol),
while connecting the graphics interface to a master
controller. This
IATC will centralize certain operating
modes, such as the "occupied/unoccupied" mode.
