Installation Wiring

1 Single Zone B80, B160, B300 Fan Systems.
THE LOCAL RELAY UNIT houses an inverter. This
converts the 230V single-phase input into a
three-phase 230V output. The inverter provides a
soft start to the motor, which extends the motor life
by minimising the start current.

6 SmartCom³ Commissioning.
For ease and swiftness of initial start-up, the
SmartCom³ range of electronic controllers is
supplied factory pre-set to operate a standard
warm air unit heater. To operate with a Nor
-Ray-Vac system however, the parameters will
have to be changed via the engineers
settings.
Follow the step by step instructions overleaf for
the correct settings. For more detailed
instructions and other engineer settings, refer to
the SmartCom³ user manual GB/
SCOM/120/0309.
5 Schematic Nor-Ray-Vac Multizone System.

MASTER & SLAVE (NETWORK)
When setting up a SmartCom³ Master and
Slave (Network) system, the master controller
will display an error message during
commissioning. This will clear once the
commissioning is complete.
REMOTE SWITCHED INPUTS
SmartCom³ controllers can be operated
remotely via a remote ON or a remote OFF
signal in the following ways:
A. Building Management System
Control (BMS).
SmartCom³ controllers can be operated via a
BMS system, by applying a volt free
connection (ie closed circuit to enable) across
terminals B1 and B0 turns the system on.
Making this connection on a master controller
will turn the entire system on whereas making
this connection on a slave unit will only bring
on that zone.

The inverter
interface
(door open)
The use of an inverter on the B80, B160, B300
fan system allows the end vent suction to be
adjusted by varying the fan speed.
The description for adjusting the fan speed is
given in the following section. Apart from this
change the commissioning section in the
manual should be followed.
End vent suction (B80, B160, B300 )
For these systems the end vent suction is
adjusted by altering the low speed setting of
the inverter within the local relay unit.
1. Check that the fan damper is fully open
and secure.
2. Ensure the SmartCom³ is in a programmed
ON time.
3. Set the required room temperature above
the actual room temperature.
4. After a 30s delay the fan should run.
5. The fan should now be running and the
inverter should be showing the motor
frequency in the display.
6. Check for correct rotation of fan.
7. Press the mode button 3 times until
‘COnF’ appears on the display.
8. Press the jog dial to enter. Rotate jog dial
until ‘LSP’ is displayed. Press jog dial to
enter. Rotate jog dial to adjust frequency.
Press jog dial to enter new value, causing
the inverter to change its speed. Adjust the
frequency until the appropriate end vent
suction is achieved, this is given in the
table below.
9. Pressing the ESC button twice will return
the inverter to the ’rdY’ display. The
setting procedure is now complete.
End vent suction (BH300 ONLY)
This unit does not feature an inverter, the end
vent suction adjustment is made using the fan
damper, details of this are given in the
Nor-Ray-Vac manual.
7 End Vent Suction Setting Procedure.
1. BMS controlling time only.
Ensure all the programmed ON times in the
SmartCom² are turned off
(i.e. They read “- -:- -”).
2. BMS controlling time and temperature.
Ensure all the programmed ON times in the
SmartCom² are turned off
(i.e. They read “- -:- -”). Set all the required
day temperatures to 30°C.
B. Remote door interlock. SmartCom³
controllers can be connected to a door
interlock, remote frost stat or permanent off
switch via terminals B2 and B0. When a volt
free connection is provided (ie closed circuit to
enable) at these terminals, the controller
reverts to FROST ONLY mode. Refer to the
individual wiring diagrams for wiring
configurations and type.
