Controls manual
Main characteristics
Generalities
The RCF units are provided with an
electrical panel including the power sup-
ply section and the controls (the 3-ways
valve for the hot water coil, if required,
and the actuators are included) to mana-
ge all the functions of the cooling circuit.
The controls include: NTC temperature
probe on the exhaust air flow, NTC tem-
perature probe for the fresh air flow, dif-
ferential pressure switch for the fresh air
filter. When the free-cooling accessory is
required, the dampers and the actuators
are provided for. A remote control panel
is also included for the remote manage-
ment of the unit (max. distance 150m,
wiring cable not included).
The main functions of the control panel
are:
• room temperature control, based on the
temperature of the exhaust air;
• management of the de-frosting proces-
ses;
• remote ON-OFF;
• Summer/Winter switch;
• electric heating coil control (if required);
• water heating coil control (if required);
• User interface with two different levels
of accessibility with password (inside the
electrical panel); • remote panel (max. distance 150m) to
be connected directly to the unit (wiring
cable not included).
Troubleshooting
The controls check and mark the fol-
lowing possible failures:
• temperature probe failure
• cooling circuit high and low pressures
• compressor thermal protection
• fan thermal protection.
Installation of remote panel
The connecting terminal of the remote
control and the connecting terminal on
the electrical panel has to be connected
by means of shielded electrical cables
with min. 0.5 mm2 section and max.
150m lenght (cables non included).
Please, refer to the paragraph “Wiring of
remote panel” for the connecting proce-
dure.
To access the keyboard on the remote
panel remove the front panel (with a
screwdriver or similar tool) as shown in
fig. 01.
The cables must pass through the central
hole in the rear section (fig. 01).
The keyboard is designed to be wall-
mounted. After removing the front part,
drill four 4 mm diameter holes in the wall
at the specified distance. Fix the black
rear part to the wall with four screws.
After carrying out the necessary connec-
tions, close the front section of the key-
board by simply pushing it in place.
