FIELD CONTROLS WMO-1 Thermal Safety Switch

The FIELD CONTROLS WMO-1 thermal safety switch is used in HVAC systems to shut down the burner or appliance if flue gas temperatures exceed safe limits. It prevents overheating and potential fire hazards in oil-fired furnaces, boilers, and water heaters by interrupting the electrical circuit when the temperature rises above its set point.

The FIELD CONTROLS WMO-1 is a thermal safety switch with manufacturer part number WMO-1. It is designed for replacement HVACR controls, switches, and thermostats. The switch monitors flue gas temperature and opens the circuit to shut down the burner when excessive heat is detected, protecting the system from damage.
