Phason TVS

Three Stage Control

Easy-to-use, automatic three-stage control

The Three Stage Control automatically controls the temperature in a room by operating two variable speed fans and a single-speed fan or heater.

Easy to use and program

The Three Stage Control comes with seven factory-configured operating programs you can easily reconfigure for your ideal situation. The easy-to-use keypad and menu system make the TVS one of the easiest controls to program. The controls 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 in a single zone. For more versatility, you can connect 4 temperature probes together and use 4-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.

You can connect the TVS to an alarm siren or other external alarm system. Customizable alarm settings allow you to choose which alarm conditions you want to be notified about.
