Description
The Emerson Climate-White Rodgers 3F11-100 93-107 Close On Rise is a snap disc temperature control system used to manage switching operations in heating and cooling equipment. It operates within a 93F to 107F range and uses a close-on-rise action, where electrical contacts connect as temperature increases to a set point. The 30F differential supports stable switching behavior during operation cycles in HV systems. It is typically placed on ducts, heat exchangers, or air handler housings to sense temperature rise and trigger fan control or auxiliary heat stages. It plays an essential role in systems by assisting air flow sequencing and temperature response control in air handling equipment.
