12.11 Zoning of the air fl ow
This option allows the management of the air
fl
ow of the unit
to condition up to 4 di
ff
erent zones with a minimum air
fl
ow of
35% (all of them in same operating mode: heating or cooling).
This function allows to adapt the indoor air
fl
ow to the installation
requirements.

The installer must carry out the following connections:
●
Connection of the zone terminals:
- Power supply (the same as the control board) at 230Vac
50/60Hz (L&N): 2 wires (section 0.5 at 1.5 mm
2
).
- Communication (RX+/TX+ & RX-/TX-): shielded cable
type AWG20 or AWG22 with 1 braided pair + dra
shielding (e.g., model BELDEN 7703NH).
Zone terminals can be installed at a maximum distance of
100 metres from the zoning box.
These terminals are con
fi
gured with their corresponding
address in the factory. In the unlikely event of a communications
failure the screen will display “
Cn
”. Please make sure to check
connections and the
fi
rmware version.
●
Connection of the servomotors for the supply dampers:
- 5 wires (section 0.5 at 1.5 mm
2
), supply 24Vac.
●
Connection to the electrical cabinet of the PJ unit:
- Power supply: 230Vac ((L&N): 2 wires (section 0.5 at 1.5
mm
2
).
- Communication (RX+/TX+ & RX-/TX-): shielded cable
type AWG20 or AWG22 with 1 braided pair + dra
shielding (e.g., model BELDEN 7703NH).
Note: Please refer to the wiring diagram provided with the unit
and the Vectic control manual to get more detailed information
about the wiring.
Zone terminals
These terminals are the same as the TCO user’s terminal
(optional).
The main screen shows the ambient
temperature, current operating mode of
the unit, time and day of the week.
The following screen shows the
temperature setpoint for this zone in the
current operating mode.
This screen can also show the zone that corresponds to the
terminal, the regulation band associated with the temperature
setpoint, the active alarms by means of codes and the delay
set for the opening/closing of the damper.
These terminals also allow the schedule programming.
With the air zoning, the VecticGD terminal it also provides
information on setpoints for each zone.
Zoning box connections
The control board of the air zoning is assembled in a separate
box from the PJ unit. This board is connected in series on the
Field-Bus of the main board of the Vectic control, placed on the
electrical cabinet of the unit.
Regulation gives the control signal to the dampers installed
in each zone (dampers and servomotors for those dampers
not supplied). The unit modifies the air flow and capacity
depending on information coming from sensors in each zone
and considering active zones in each moment.
The option includes 4 zone terminals (one for each zone), the
additional control board supplied in an independent box to be
connected with the 4 terminals, the unit board and also to the
servomotors that control dampers in each zone (dampers and
servos not supplied).
The temperature information for each zone is coming from
temperature sensor integrated inside each zone terminal. It is
not needed to install any extra ambient sensor.
