The Phason Three Ventilation Stage Control (TVS) automatically controls the temperature in a room by operating two variable speed fans and a single-speed fan or heater.
The control comes with seven 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 has a 30' temperature probe the monitors temperatures from -49° F to 122° F in a single zone. For more versatility, you can connect four temperature probes together and use four-zone averaging.
The TVS displays alert conditions such as high and low temperatures, power failure, and low line voltage, and can connect to an alarm system, alarm panel, or auto-dialer. Customizable alarm settings allow you to choose which alarm conditions you want to be notified about.
