Johnson Controls A36AHB-1 2-SPDT 4-Stage Multi-stage Thermostat Control 10°F to 90°F 15' Capillary

The Johnson Controls A36AHB-1 multi-stage thermostat control offers accurate temperature control for a broad range (10°F to 90°F). This robust device comes with a remote sensor bulb that is attached to the main unit by a long 15-foot flexible copper capillary to allow for more installation choices. The copper bulb effectively conducts heat, so the temperature is sensed accurately in a controlled environment. The control unit consists of two single-pole double-throw (2-SPDT) switches with each stage having its differential adjustment. This allows selective triggering or deactivation of heating or cooling apparatus in a stepwise manner in response to fluctuation in temperatures.
