Adjustable Thermostat with Firestat for Power Attic Ventilators

Quick Overview


This unit features a fusible link which will shut off your attic or exhaust fan in unsafe operating conditions exceeding 183° F, and is also used for the daily operation of your fan as a typical thermostat. This thermostat mounts to a rafter using wood screws and has a wiring diagram provided to complete installation. As a general rule for power attic vents, your normal temperature setting will range from 95 - 115° F depending on average regional temperatures—a setting too low will run the fan continuously, and a setting too high will result in insufficient air turns for proper ventilation.

This thermostat is compatible with our roof and gable mount power attic ventilators (excluding solar vents), as well as exhaust fans (IF14 - IF36). Not for use with whole house fans.

  • Adjusts from 50 - 120° F. Controls up to 3 units, not to exceed 10 amps.
  • Firestat safety fusible link will cut fan off at 183° F
