Wall-mounted HVAC heat control

The Fostoria VHC-32 is a wall-mounted variable heat controller with a positive off switch. It operates on 208/240V AC single-phase power at 60 Hz and handles up to 3200W. The unit includes the control knob and is rated for 15.4A amperage.

Suits Fostoria 222-Series and OCH heaters

This control suits installations using Fostoria 222-Series heaters at 208/240V up to 3200W or OCH models at 208V up to 3000W. Buyers with heaters outside those model lines or voltage ratings should look at a different controller. It is not for three-phase supplies or loads above the stated wattage.

Sustained load at rated wattage

Under continuous operation the controller manages the full 3200W rating at 240V or 3000W at 208V on compatible heaters. The positive off switch breaks the circuit cleanly when turned off. The 15.4A rating reflects steady-state current draw at maximum output.
