Dual Thermostat/Humidistat Control for Power Attic Ventilators

Reduce both moisture and excess heat in your attic with this dual thermostat-humidistat control to avoid mold and mildew issues, prolong the life of your roofing components, and reduce your energy costs when paired with your electric attic fan. This controller 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 and humidity setting from 60 - 70% depending on average regional temperatures and local humidity levels—a setting too low will run the fan continuously, and a setting too high will result in inadequate ventilation.

This control is compatible with our roof and gable mount power attic ventilators (excluding solar vents). Not for use with whole house fans.
