This typically points to a mismatch between the EPROM BIOS version and the installed Flash Memory Card

This relay is a staple in dual-duct VAV sequencing and for converting Constant Air Volume (CAV) systems to Variable Air Volume (VAV) architecture

it reacts to internal pressure and temperature changes to optimize heat exchange

this thermally protected unit features 3/8-inch suction and discharge line connections

York 025-40273-004 Temperature Sensor 319852-301 you must use the MTZThe York 025 40273 004 is a precision engineered leaving water temperature sensor designed for integration with high efficiency York chillers and HVAC systems. This thermistor style sensor provides critical feedback to the chiller control board, allowing for accurate monitoring of evaporator leaving water temperatures. Operating with tight resistance to temperature curves, this component ensures the HVAC control system can prevent freeze up conditions
