Chapter 1: Introducing the PEC Plus
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.
