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 5 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.
Chapter 1: Introducing the TVS Phason 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.
TVS user manual Introducing the TVS Optional accessories Several optional, convenient accessories are available to enhance and extend your TVS. TVS Saver The TVS Saver is an innovative and easy-to-use product that stores a complete copy of a TVS's configuration and settings.
Chapter 1: Introducing the TVS Phason Power contactors Phason’s 240-volt power contactors are heavy-duty relays that increase the load handling capability of control relays. Power contactors are ideal for secondary ventilation fans and electric heaters. Power contactor relay (PC-240): includes power contactor relay and mounting hardware for easy mounting in an enclosure.
TVS user manual Becoming familiar with the TVS KTVS-B has standard, soldered relays. This control board comes with the TVS standard version. K102208-RS has socketed, pluggable relays. This control board comes with the TVS RS version. Either circuit board works with any PEC Plus control. The advantage of the RS version is that you can replace individual relays instead of the whole circuit board. Replacement relays If you have the TVS RS version, the relays in the bottom circuit board are replaceable.

Chapter 2: Installing your TVS Chapter 2 explains how to mount, install, and connect equipment to your TVS. Topics in chapter 2 include: What you need to know before installing your TVS below Connecting equipment to your TVS on page 14 Finishing the installation on page 22 What you need to know before installing your TVS Before installing your TVS, you need to do some initial preparation: 1. Read Understanding power surges and surge suppression on page 9.
TVS user manual What you need to know before installing your TVS Understanding power surges and surge suppression Power surges can be caused by external influences (for example, lightning or utility distribution problems) or they can be caused internally (for example, starting and stopping inductive loads such as motors). One of the most common causes of power surges is lightning. When lightning strikes the ground, it produces an enormously powerful electromagnetic field.
Chapter 2: Installing your TVS Phason Install a filter in parallel with the load, as shown in the following example. Do not use Snubber filters with variable stages. Some power contactors include snubber filters. For more information, read Using power contactors to increase the capacity of relays on page 11. For more information about snubber filters or other Phason accessories, see your dealer or visit www.phason.ca.
TVS user manual What you need to know before installing your TVS Using power contactors to increase the capacity of relays Phason’s 240-volt power contactors are heavy-duty relays that allow you to increase the load handling capability of control relays. Power contactors are ideal for secondary ventilation fans and electric heaters. Phason’s power contactor relays have the following electrical ratings. Coil: 10.
Chapter 2: Installing your TVS Phason Mount the control on a sheltered, vertical surface, with the electrical knockouts facing down. Use a screwdriver to tighten the screws in the enclosure. Do not use a drill or over tighten the screws; this can crack the enclosure and ruin the watertight seal. Use the electrical knockouts for bringing wires or cables into or out of the enclosure. Use watertight strain reliefs or conduit connectors at all cable-entry points.

You can use this configuration as an override.
Chapter 3: Configuring your TVS Phason Testing the configuration After configuring all the control elements (variable stages, relays, and so on), test your TVS to make sure the configuration is correct. In other words, make sure what you think is connected to a particular relay or stage is actually connected to that relay or stage. You can test the configuration using the TVS's stage override mode. Stage override mode allows you to operate the equipment, regardless of temperature or time.
Chapter 4: Programming the TVS Chapter 4 discusses how to program your TVS with the settings it uses to control your equipment. What you need to know before programming your TVS Programming the TVS basically means telling the control what you want it to do with the equipment and when you want it done. For example, for a single-speed fan set for cooling, you might say "Switch on when the temperature reaches 80°F.
Chapter 4: Programming the TVS Phason Understanding how the TVS operates Understanding how the TVS operates can help you configure and program your control more efficiently, and control your environment more effectively. The configuration and settings for the following example are the factory defaults for program A. 1 Group set point is the target temperature for the room. 2 Stage 1 idle speed is the speed, in percentage of full power, at which the stage 1 fan operates for minimum ventilation.

Appendices The appendices contain reference information that is useful when installing, configuring, setting up, or troubleshooting your TVS.
Appendices hysteresis Phason The number of degrees above the set point that a heating stage or relay switches off, and the number of degrees below the set point that a cooling stage or relay switches off. For example, a household thermostat might switch on a furnace at 68 °F when the house is cooling down, but switch it off at 72 °F when the house is warming up. The difference between these two values is the hysteresis. For more information, read Configuring hysteresis, parameter 18 on page 25.
