Caution–Hazard of Fire: Types AR, ARR, AR-LT and AR-EP thermostats do not provide failsafe temperature controls for heating. If the thermostat bulb ruptures, the controller senses that the temperature is not at the setpoint and heat stays on. A backup high limit temperature controller is recommended for safety. *Not intended for use in hazardous areas.
