Qmark Whole House or Bathroom Fan Timers
Qmark Spring Wound Timer Switches are energy saving timers use no electricity to operate and are designed to replace any standard wall switch, single or multi-gang, and automatically limit the "ON" time of fans and lights.
Models are available with a "hold feature" which allows the user to override the automatic shut-off function for extended use of the load as required. Most commercial, municipal, educational and industrial facilities require the features of without the hold to ensure continued energy savings.
Use for House Fans, Electric Baseboard Heaters, Wall Electric Fan Heaters, Electric Toe-Kick Heaters and other Electric Space Heaters where you want to keep on for five minuets or less.
