The A19BAG special thermostat for portable heaters is a singlepole, single-throw control with contacts opening on a rise in temperature. The thermostats are supplied with an adjustable range and a fixed differential. A "No Heat" position on the dial permits manual shutdown of the heater without disconnecting the thermostat or the power supply. A special 3-wire extension cord and "series plug" are an integral part of this control to permit "plugging" the heater cord into the thermostat extension cord for automatic operation. A beaded chain hanger is supplied to permit supporting the thermostat in any convenient location.

The A19BAG is a sturdy, compact thermostat with a visible scale and an adjustable set point knob. An exposed helical sensing element is specially designed and field proven for rapid response and dependability. The enclosed snap-acting contacts are dust protected. The thermostat has a NEMA Type 1 enclosure and is designed for portable heater applications. A strain relief bushing on the extension cord minimizes undue strain on the wire connections at the terminals.
