Original equipment manufacturers worldwide use thermostat switches that are designed and manufactured by Senasys Inc. No matter which style or model you choose, all of the Firestat Duct Fan and Limit Thermostat Switches operate using the same physics to ensure HVAC safety. A helix bi-metal element senses a rapid temperature change. When the temperature changes the bi-metal expands and triggers a snap action switch and either opens or closes a circuit.
