Chapter 1: Introducing the TVS
Chapter 1 introduces you to the Three Ventilation Stage Control (TVS). Read chapter 1 before
reading the rest of the manual. Topics in chapter 1 include:
Introducing the TVS below
Becoming familiar with the TVS on page 9
Introducing the TVS
The TVS automatically controls the temperature in a room by operating two variable speed fans and
a single-speed fan or heater. To control the temperature, the TVS operates the connected ventilation
and/or heating equipment according to programmed settings.
Easy to use and program
The control comes with four factory-configured operating programs you can easily adjust for your
situation. The easy-to-use keypad and menu system make the TVS one of the easiest controls to
program. The TVS's advanced and powerful features are never more than a few keystrokes away.
Versatility and peace of mind
The TVS has a 30-foot temperature probe that monitors temperatures and a single zone. For more
versatility, you can connect four temperature probes together and use four-zone averaging.
Temperature probes are available in 1, 6, 30, 75, or 150-foot lengths; you can extend them up to 500
feet using extension cable.
The TVS displays alert conditions such as high and low temperatures, power failure, and low line
voltage, and can also connect to an alarm siren, alarm panel, or auto-dialer. Customizable alarm
settings allow you to choose which alarm conditions you want to be notified about.
Common applications
Livestock applications
Livestock applications include buildings housing calves, rabbits, goats, hogs, poultry, and turkey. In
these applications, the TVS often controls ventilation in a single 20 x 40-foot or smaller room.
Greenhouse applications
Greenhouse applications include controlling ceiling louvers, variable and single-speed fans, and
heaters.

Business and light-industrial applications
Business and light-industrial applications include machine shops, garages, and utility sheds where
customers use the TVS to control fans and heaters. The TVS exhausts heat from the room made by
equipment and/or regulates the temperature as service bays open and close.

Thirty-foot temperature probe, extendable to 500 feet
 Easy System compatible –edit and store configuration and settings on a computer. For more
information, visit www.phason.ca.
Rugged enclosure (corrosion resistant, water resistant, and fire retardant)
CSA approval
Two-year limited warranty

Becoming familiar with the TVS
The four-character LED display shows temperatures, alarm messages, and programming
information. If there is a dot in the top left corner of the display, you are in an editable menu. This
means you can adjust the parameter.
If you leave the TVS 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 override mode and temperature override mode; the control
remains in these modes until you manually exit them.
