Fan and Limit Controls

A forced air heating system circulates warm air through a property via vents and ducts. To help this work as effectively as possible, our fan and limit controllers help provide control of high limits and fan motors in all types of forced air systems. The bimetal sensing element turns the fan on and off according to the supply plenum temperature. When it comes to installation, mounting adapters make replacing devices convenient. Strain relief bushing will help to prevent field abuse damage.
