Description
The Johnson Controls A19ADC 31 Remote Bulb Temperature Control is a device that helps to control temperature in HVAC systems. This device consists of two major components, a remote sensor bulb and a control unit linked by a 6-feet capillary tube. The copper bulb which is well known for heat transfer is installed in the air duct or environment that requires heating or cooling. It applies a Single-Pole Double-Throw (SPDT) toggle switch to control heating and cooling systems in response to temperature differences. This has an “Open-High” type of manual reset function. In case the device overheats, the control cuts off power and must be manually enabled to continue operating.
