The Stanley SAR3931 thermostat is an analog thermostat with a range of 0-120 degrees Fahrenheit. It is normally used as a supplemental heat source for central air and heating systems, such as providing an auxiliary heat source for forced air systems. This thermostat requires the use of a transformer for power, and the power rating for the transformer must be greater than or equal to 2.5 VA. It also includes a set point adjustment knob, start/stop switch, and circuit breaker. The SAR3931 thermostat is designed to be easily wall mounted and requires no additional mounting hardware.
