Adjustable, programmable attic ventilator thermostat designed to the original control on single‑speed power attic ventilators. Provides reliable automatic on/off control so your attic fan runs only when needed, helping protect roof structure and reduce cooling load on the home. Why you need it Keeps attic temperatures in check by turning your power attic ventilator on at a preset temperature or on a programmed schedule. Reduces wear and tear and energy waste by preventing the fan from running continuously. Simple replacement solution when the original thermostat fails or when you want programmable control. Key benefits Automatic temperature control: activates the attic ventilator when attic heat rises above your setpoint and turns it off when the attic cools. Programmable operation: allows scheduled on/off control to match usage patterns and weather, improving efficiency. Single‑speed compatibility: engineered specifically as a replacement for single‑speed power attic ventilators for reliable operation. Adjustable settings: set the temperature and program parameters to suit seasonal needs and local climate. Quick replacement: designed to swap in for existing attic fan thermostats without complicated rewiring. Main features and attributes Functionality: temperaturesensing thermostat with adjustable and programmable controls for automated fan operation. Compatibility: intended for use with single‑speed power attic ventilators as a direct replacement control. Performance: maintains consistent attic control to reduce peak attic temperatures and unnecessary fan runtime. Form factor: replacementstyle housing suitable for installation in locations normally occupied by the original thermostat. Reliability: built for steady, longterm control of attic ventilation equipment. Use cases a failed thermostat on an existing single‑speed attic ventilator to restore automatic operation without replacing the fan. Add programmable control to an older attic fan so the unit operates on temperature thresholds and timed schedules, lowering summer cooling load. Control attic ventilation seasonally — set tighter control during hot months to reduce attic heat gain and relax settings in cooler months to preserve heat. Installation and operation notes Designed as a direct replacement for the thermostat on single‑speed power attic ventilators; installation typically follows the same wiring and mounting points as the original control. Adjustable setpoints and programming allow for local conditions and homeowner preferences. For safe installation, follow the ventilator manufacturer's wiring diagram and turn power off before servicing. Consult a qualified electrician if unsure. What makes it different Combines simple replacement compatibility with adjustable, programmable control so you get the convenience of automation without replacing the entire ventilator. Focused on single‑speed ventilator systems to ensure straightforward installation and dependable performance. This thermostat is a practical, cost‑effective way to regain control of attic ventilation, improve efficiency, and protect your attic and HVAC system by ensuring the ventilator runs only when .
