Main display
The main display shows the temperature and any alarm messages. The main display is what you see
when you are not in a menu or settings display.
Here are some things to know about the main display.
When a relay is on, the status LED for that relay is lit.
When there is an alarm condition, the display flashes between the alarm message and the current
temperature. For more information about alarms, read Alarm settings and conditions on page
13.
When the control is in manual override mode:
For the curtain, the Open and Close LEDs will blink three times and then stay off for one
second.
For the heater, if the heater is ON, the Heat LED will blink three times and then stay ON
for one second; if the heater is OFF, the LED will blink three times and then stay OFF for
one second.
For more information, read Using manual override mode on page 16

Connecting the temperature probe
Follow the guidelines below when installing and connecting the temperature probe.
Do not run the probe cable in the same conduit as
AC power cables
Do not run the sensor cable beside AC power
cables or near electrical equipment.
When crossing other cables or power lines, cross
them at a 90-degree angle.
Replace damaged probes as soon as possible. If there is no probe present or
working properly, the NVC displays either pd (probe damage) or ps (probe short)
and switches off the relays.
Connecting an alarm system
An alarm system can be a siren, an alarm panel, or an auto-dialer. See your alarm siren’s installation
guide for installation instructions and information about the type of system:
The descriptions for the alarm terminal are as follows: CC–common connection, CA–closed on
alarm, OA–open on alarm.
To connect an alarm system
If you are connecting the alarm system to a
network of controls and your system uses a
normally open connection (closes on alarm),
connect the system as shown in the normally open
diagram.
Join all the common (CC) connections together
and all the closed-on-alarm (CA) connections
together. The NVC alarm relays must be in parallel
with each other so any control can trigger the
alarm system when an alarm condition occurs.
Normally open system (closed on alarm)

Natural Ventilation Control Phason
8 2014-04-10
If you are connecting the alarm system to a
network of controls and your system uses a
normally closed connection (opens on alarm),
connect the system as shown in the normally
closed diagram.
Join the alarm relays in a continuous loop. The
NVC alarm relays must be in series with each other
so any control can trigger the alarm system when
an alarm condition occurs.
Connecting the power source
DC model NVC-2-12 (12 VDC, 250 mA)
DC model NVC-2-24 (24 VDC, 125 mA)
Before connecting the incoming
power, switch OFF the power at the
source.
Do not switch ON the power until
you have finished all wiring and
verified all equipment is properly
connected and free of obstructions.
Finishing the installation
1. Make sure all wires are properly connected to the correct terminals.
2. Place the cover on the control.
3. Switch on the power to the NVC; it should display ŠŠŠŠ for three seconds, the version (for
example, vƒ00) for three seconds, and then the temperature.
If the display does not light up, go back to step 1.
If the display shows an alarm message, or the LED for Alarm is flashing, press Select to
acknowledge the alarm. For a list of alarm messages and error codes, read Alarm messages
on page 13.
4. Test the equipment. For more information, read Testing and maintaining the NVC on page 15
5. Fasten the cover to the base.
Normally closed system (open on alarm)

Phason Natural Ventilation Control

Programming the NVC
Before you begin programming the NVC, make sure the control has power and you have properly
connected all equipment to the correct terminals .
How the curtain settings work
There are six curtain settings.
Set point – the temperature at which the curtain holds its position.
Idle band – the buffer around the set point within which the curtain holds its position.
Open on duration – the duration the curtain opens during the open cycle
Close on duration – the duration the curtain closes during the close cycle
Open off duration – the duration the curtain holds its position during the open cycle
Close off duration – the duration the curtain holds its position during the close cycle
Curtains hold their position while the temperature is within the Idle band of the Set point. For
example, if the Set point is 80°F and the Idle band is 4°F (+/- 2°), the curtain holds its position
when the temperature is between 78°F and 82°F.
If the temperature rises above the Idle band (above 82°F in our example), the curtain opens for the
Open on duration. After opening, the curtain holds its position for the Open off duration. If the
temperature is still above the Idle band, the curtain again opens for the Open on duration, and the
process repeats.
If the temperature drops below the Idle band (below 78°F in our example), the curtain closes for the
Close on duration. After closing, the curtain holds its position for the Close off duration. If the
temperature is still below the Idle band, the curtain again closes for the Close on duration, and the
process repeats.
