Phason controls are designed and manufactured to provide reliable performance, but they
are not guaranteed to be 100 percent free of defects. Even reliable products can experience
occasional failures and the user should recognize this possibility.
If Phason products are used in a life-support ventilation system where failure could result in
loss or injury, the user should provide adequate back up ventilation, supplementary natural
ventilation, or an independent failure-alarm system. The user's lack of such precautions
acknowledges their willingness to accept the risk of such loss or injury.

Chapter 1: Introducing the PEC Plus
Chapter 1 introduces you to your PEC Plus and the layout of this manual. Read this chapter before
reading the rest of the manual.
Topics in chapter 1 include:
Introducing the PEC Plus below
About the manual on page 4
Becoming familiar with the PEC Plus on page 5
Introducing the PEC Plus
The PEC Plus is designed to control ventilation equipment for a single room. The eight-stage
control has two variable cooling stages for controlling fans and six relay stages for controlling
equipment such as actuators, curtain machines, single-speed fans, and heaters.
The control comes with a 30-foot temperature probe that is extendable to 500 feet. Automatic four-
zone temperature averaging and outdoor temperature monitoring are available with additional
temperature probes.
The PEC Plus automatically monitors and controls the temperature by operating ventilation
equipment such as fans, heaters, inlet actuators, curtain machines, or other equipment according to
your programmed settings.
The seven-step growth curve is a powerful feature that allows you to program the control to
automatically adjust the temperature set points over time to control the temperature in a room or
zone. This is an ideal feature to use as your animals grow and their temperature requirements
change.
The PEC Plus is ideal for poultry, livestock, greenhouse, or light-industrial buildings and is
compatible with most ventilation strategies: natural, forced, tunnel, and chimney ventilation.
Easy to use and program
The PEC Plus's display shows the ambient temperature and any alarm messages. During normal
operation, the status LEDs show when the stages are on.
When in programming mode, the LEDs indicate which stage you are programming. The easy-to-use
keypad and menu system make the PEC Plus one of the easiest controls to program. The PEC Plus’
advanced and powerful features are never more than a few keystrokes away.

Security and peace of mind
The PEC Plus has a PIN (personal identification number) security system. When you enable
security, users must enter the PIN before they can access a specific menu or function. This allows
you to control who makes changes to your system and its settings.
The PEC Plus is compatible with most alarm systems. You can connect your PEC Plus to an alarm
siren or other external alarm system. The customizable list of alarm settings allows you to choose
which alarm conditions you want to be notified about.

Caution
This is a caution. It contains important information that you must follow when
installing or servicing your PEC Plus. Failure to follow this information can lead to
damaged controls or equipment.
Warning
This is a warning. It contains important safety information that you must follow when
installing or servicing your PEC Plus. Failure to follow this information can lead to
damaged controls or equipment, electrical shocks, or severe injury.
Becoming familiar with the PEC Plus
The PEC Plus has a four-character LED display, status LEDs for each variable stage and relay,
function LEDs, and 10 buttons for programming and interacting with the control.

Chapter 1: Introducing the PEC Plus Phason

Main display
The four-character, seven-segment LED display shows ambient
temperatures, alarm messages, and programming information.
If you leave the PEC Plus in a menu or display other than the main display, the
control returns to the main display after five minutes without any key presses. The
only exceptions are stage test mode and temperature test mode; the control
remains in these modes until you manually exit them.
Buttons
The five main control buttons (Function, Down,
Up, Back, and Select) allow you to scroll through
the function menus and enter programming information.
The Parameter buttons display temperature information and allow you to select which settings, or
parameters, you want to program.

Chapter 2: Installing your PEC Plus
Chapter 2 explains how to mount, install, and connect equipment to your PEC Plus.
Topics in chapter 2 include:
What you need to know before installing your PEC Plus below
Connecting equipment to your PEC Plus on page 14
Finishing the installation on page 25
What you need to know before installing your
PEC Plus
Before installing your PEC Plus, you need to do some initial preparation:
1. Read Understanding power surges and surge suppression below.
If you do not install external surge suppression devices, you risk damage to the
electronics inside your PEC Plus, which may cause your PEC Plus to fail.
Because it is not possible to completely protect this product internally from the
effects of power surges and other transients, we highly recommend that you
install external surge suppression devices. For specific recommendations, see
your electrical contractor.
If you do not take these precautions, you acknowledge your willingness to
accept the risk of loss or injury.
2. Using Appendix D: Installation worksheet on page 84, list all the equipment you want to control
using this PEC Plus. Install the equipment and make your electrical connections according to the
sheet.
3. Using Appendix E: Configuration worksheets on page 86, decide which relays and variable
stages you want to use for each piece of equipment, and how you want the equipment
configured. You can connect more than one piece of equipment to a single relay or stage as long
as the total current draw does not exceed the relay or stage’s limit. For more information, read
Electrical ratings on page 10.
Understanding power surges and surge suppression
Power surges can be caused by external influences (outside the barn – for example, lightning or
utility distribution problems) or they can be caused internally (inside the barn – for example, starting
and stopping inductive loads such as motors).

Chapter 2: Installing your PEC Plus Phason
10 2009-06-15
One of the most common causes of power surges is lightning. When lightning strikes the ground, it
produces an enormously powerful electromagnetic field. This field affects nearby power lines, which
transmit a surge to any device connected to it, such as lights, computers, or environmental controls
like your PEC Plus. Lightning does not have to actually strike a power line to transmit a surge.
Surge suppression devices offer some protection from power surges. Because it is not possible to
internally protect this product completely from the effects of power surges and other transients,
Phason highly recommend that you install external surge suppression devices. For specific
recommendations, see your electrical contractor. If you do not take these precautions, you
acknowledge your willingness to accept the risk of loss or injury.

cYou can connect more than one piece of equipment to a variable stage or relay as long as they are
the same type (for example, two fans) and the total current draw does not exceed the stage’s limit.
The FLA (full load ampere) rating accounts for the increase in motor current draw
when the motor operates at less than full speed. Make sure the motor/equipment
connected to the variable stage does not draw more than 7 FLA.
