Description
The Johnson Controls A19AAF-32 Remote Bulb Temperature Control is an advanced thermostat that is used for controlling temperature of HVAC systems. Available in a 3/8 size, it works under a temperature range of 25°F to 225°F. This remote bulb-type control employs a 10ft capillary which is sensitive to temperature change. It operates on dual voltage of 120V or 240V and is connected by SPDT switches, which ensure a reliable switching for heating and cooling. This control is widely applied in refrigeration, air conditioning, and other HVAC devices where the temperature measurement is carried out from a distance. Advantages are better stability in temperature control, modularity because of the longer capillary, and compatibility with other HVAC systems.
