INSTALLATION AND MAINTENANCE

PROBE INSTALLATION
The EVO controller manages the following probes:
Air temperature reading probe installed inside the
user unit; it does not require any special installation
operations.
Probe (optional and alternative to the previous one)
connected to the I/O board for temperature readings of
the air taken in by the machine, or in any other point of
the room subject to temperature adjustment (REMOTE
AIR PROBE)
Probes (optional) for water temperature readings: it is
possible to connect one or two probes, depending on
whether the unit is connected to a 2- or 4-pipe system.
Probe (optional) to read the relative ambient humidity,
connected to the I/O board
To avoid interference, and subsequent faulty
operation, the probe cables must NOT be set
up near power cables 8230V).
REMOTE AIR PROBE INSTALLATION
Use of the remote air probe to adjust the room temperature
is optional. When it is used, it becomes the main adjustment
probe, in place of the probe installed inside the user unit. It
is always possible to choose the main room temperature
adjustment probe from the "air probe" parameter contained
in the CONFIGURATION MENU.
The remote air probe must always be connected to clamps
I1-C1 on the I/O board.
FLAT - 2X1
Use the adhesive plastic probe-holder located on the side
wall of the screw feed. Pass the probe cable (black) through
the opening in the plastic probe-holder and fasten the probe
in place by inserting it by its leg (the part covered by the
rubber sheath).

Use the supplied adhesive plastic probe-holder:
Fan coil without base (figure 05)
Fan coil with base (figure 06)
Fan coil with front suction (figure 07)
HUMIDITY PROBE INSTALLATION
The humidity probe is an optional accessory. If one is
installed, it must be connected to the SU-SU clamps on
the I/O board. The probe sensor can be positioned where
it will be in contact with the air flow of the unit's suction
circuit (if there is also a remote temperature probe, strap
them together as illustrated in the figure below) or in any
other point in the room subject to temperature and humidity
adjustment.
IT IS also possible to position the probe sensor inside the
user unit using the relative hook on the base of the unit
(figure 08).
The cable supplied with the humidity sensor is equipped
with a shield. There is no need to connect this shield to
the I/O board. If interference from near-by power cables or
other is affecting the relative humidity reading, connect the
aforementioned shield to the GND clamp on the RS485 serial
port.
