The ET 141 high limit control thermostat is duct mounted and has a rigid bulb, bi-metal rod and tube construction.
Normally, the thermostat is used as a high limit control when a "lock-out" type control is desired or required by local code. Often it is located in a return air duct and is wired to shut down air conditioning or ventilating fans when the duct air temperature becomes excessive.
