TEMPERATURE HIGH LIMIT SWITCH
As a safety device, a surface mounted high temperature cut-off switch with manual reset, factory set at 190° F is provided. In the event of an over-temperature condition, the thermostat will disengage the power from the unit, (in the HSE model the thermostat will disengage the operating coils in the magnetic contactor). The high limit must be manually reset thereafter to restart the heater.
