This HVAC motor speed control is essential for maintaining efficient system operation in low ambient conditions

it serves as an OEM-quality HVACR replacement that stabilizes starting cycles and protects the compressor’s start windings from excessive heat during the cut-in phase

ensuring consistent manifold pressure regardless of supply fluctuations

the Sporlan 311710P delivers the mechanical performance and electrical stability necessary to prevent valve chattering and premature failure in normally closed refrigeration valves

Schneider Electric (Barber Colman) 2323-503 Pressure Transmitter THPU32HP7Y This HVAC motor speed controlThe Schneider Electric 2323 503 Pressure Transmitter is a precision pneumatic differential pressure sensor engineered for low pressure HVAC automation and VAV box control. This Barber Colman legacy series transmitter provides a linear 3 to 15 psi pneumatic signal proportional to the sensed static pressure or differential pressure, operating within a bipolar range of 0. 5 to +0. 5 inches Water Column (W. C.). Designed for high reliability air handling
