Description
The Bard HVAC 8620-080 is an OEM fan/limit switch designed to deliver dependable temperature-based fan control and high-limit protection in Bard heating and HVAC systems. Rated at a 75°C setpoint with a continuous-input (CI) auto-reset configuration, this switch automatically cycles the blower fan on and off based on heat exchanger temperature while simultaneously guarding against overheating conditions.
How It Works
The fan/limit switch serves a dual purpose in forced-air heating systems. The fan function energizes the blower once the heat exchanger reaches the appropriate operating temperature and de-energizes it after the heat source shuts off, maximizing heat delivery efficiency. The limit function acts as a safety cutout, interrupting the burner circuit if temperatures exceed the rated threshold — protecting the heat exchanger and surrounding components from heat damage.
