DESCRIPTION:
Electronic control device designed to control the temperature from 2 to 16 independent zones in centralised duct type air
conditioning installations. The room wireless thermostats are connected by radio, with a central control panel which manages the motorised dampers
installed in each zone and the ON/OFF of the ducted Fan-coil unit (FCU).
2.
SYSTEM WIRING:
All of the system components are wired to the control centre. It is
recommended that you locate it close to the inner unit of the air conditioning equipment,
placed in an elevated position and far from metallic parts. Place that control panel not
accessible to the general public. Fix it into the wall using screws or use the rear DIN rail
fixation.
2.1. Power:
Supply the centre with 230 VAC on the
Power Supply
terminals, wires Smin=1
mm
2
, Smax=1.5 mm
2
.
2.2. Antenna:
Locate and aim the antenna in the false ceiling in a place where radio signal reception is favourable.
2.3. Motorised dampers:
Connect the motors for each regulation to terminal blocks 1 to 8 on the board. Use a wire (red (+) / black (-)) Smin=0.75
mm
2
, Smax=1.0 mm
2
. In the event of two regulations per zone (maximum recommended), connect the parallel as indicated in Zone 5 of the figure. The
MASTER zone should be connected to output 1.
For more than 8 zones, an expansion module should be used for up to 16 zones, which must be connected using the connection cable supplied with
the module to the
Input/Output Expansion Modules
on the control board.
2.4. Fan-coil:
There are 3 types of wiring between the central control and the Fancoil depending on the type of installation
.

Installation TYPE 2
Installation TYPE 3
Multiple or individual installations
with 2 pipes (Cool/Heat)
with 2 pipes (cool /Heat) + Electric heater.
Multiple or individual installations
Multiple or individual installations
with 4 pipes (cool coil+ heat coil).
2.5. Water sensor (S1):
The NTC sensor measures the temperature entering at the
Fancoil to inform the zone control if the Chiller is working in heating or in cooling mode.
It is obligatory to install the NTC sensor in installations with 2 pipes +
electrical batterie
2.6. Power-free inlets (remote ON/OFF):
These work as a normally-open voltage-free contact. They provide remote access to the centre from
domotics equipment, fire or smoke detection centres, etc. On closing the contact, the centre will carry out a switching off cycle and will automatically
reset if the contact re-opens.
3. CONFIGURATION:
The number of zones controlled by the board and the type(s) of machine controlled using the system must be configured through
the control panel menus..
3.1. Selecting No. of zones:
This must be configured
in all cases
where the number of zones if different to 4 (default). From 2 to 16 zones can be
selected, of which 2 to 16 are connected to the central unit and the remainder to an expansion module.
1. Press SET for 5 s
2. Select the number of zones
3. Confirm with the central button
The equipment is restarted and will begin to work with the new no. of zones selected.
