Description
The Honeywell TP971A2003/U 2-Pipe Direct Acting Pneumatic Thermostat is a proportional air pressure temperature controller used to regulate room temperature by modulating pneumatic valves and damper actuators in response to changing space conditions. It operates within a 60F to 90F temperature range and provides 1318 PSI control pressure for accurate proportional output in pneumatic control networks in HVAC systems. It is used where pneumatic automation systems manage heating and ventilation equipment. It operates as the sensing and control system, converting temperature changes into calibrated air pressure signals that adjust connected actuators, maintaining stable indoor conditions and consistent equipment response.
