AAON ASM01891 Two Condenser Head Pressure II Module [New]

The AAON ASM01891 Two Condenser Head Pressure II Module (HP2C2) is an Orion Controls board used on AAON units with two physically separate condenser sections. It monitors up to four individual head pressure transducers (two per section) and controls two condenser fans or water valves, using the highest of the two readings for each section to drive Condenser Signal A and Condenser Signal B.

On heat pump units, the module detects Heat Pump Heating mode and forces the condenser signal to 100% until the unit leaves that mode. It can operate stand-alone - with the head pressure setpoint adjusted via the onboard OPTIONS dip switch - or connect directly to VCM-X Modular E-BUS, VCM-X WSHP E-BUS, or SA E-BUS controllers to receive setpoints from the unit controller. An E-BUS cable is included.
