TPI Fostoria VHC-32 Variable Heat Controller



The Fostoria VHC-32 Variable Heat Controller is a solid-state power control designed to provide a convenient way to adjust heat output on electric infrared heating elements. The faceplate includes an ON/OFF switch that glows red when the controller is in use. It also includes the heat intensity control knob. Use the VHC-32 to control heaters on patios, in shelter houses or other protected outdoor environments. It is designed for use with 208 or 240 volt Fostoria Mul-T-Mount 3200 watt heaters. It can operate quartz lamps or quartz tubes up to a maximum of 3200 watts.

The initial current inrush of T3 quartz lamps is very high; as much as 10 - 15 times the steady state current. Operating the VHC-32 with more than two (2) 1600W quartz lamps may damage the control. This concern is not applicable to quartz tubes or other constant-resistance elements.

Faceplate may become warm to the touch during use. This is normal.

Not for residential use.
