EDM SYSAER R32 (EDM AER R32 01 S 2GB)

SYSAER R32
4
The SYSAER R32 can be equipped, according to the
specications of the customer, with an additional
heating system. This equipment is installed and
tested in the factory.
Heating
Electric heating
The electric heating battery is available on all of the
congurations of the SYSAER R32. 1 power level of
48kW is available to adapt to the entire SYSAER R32
range.
The regulation makes it possible to control 2 power
stages in order to adapt the electrical consumption to
the heating needs.
An air ow rate detector associated with 2 automatic
and manual reset thermostats provides the safety for
the electric heating function.
Specications
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.
The objective of the R32 leakage detector card is:
² To detect R32 leakage that could occur in the
product,
² To stop the unit by controlling the energy
supply of the compressors,
² To alarm that leakage is detected,
² To supply air distribution in case of leakage for
discharging the unit.
The table shows the maximum refrigerant limit before
considering a leakage on the units:
Gas leak detector
CO
2
room sensor with active/switching output,
automatic calibration (can be switched off), for
determining the CO
2
content in the air (0...2000
ppm / 0...5000 ppm). The transmitter converts the
measured values into a standard signal of 0 -10 V or
4...20 mA (switchable).
If a CO
2
sensor is connected to the unit, the value
of the minimum is calculated according to the CO
2
content. The value measured by the sensor can be
read on the main display. The user could set the ppm
number up to which the minimum amount of fresh air
is present and read the number of ppm from when
100% fresh air is used.
