Description: ICM Controls ICM325A Low Ambient Head Pressure Control Air conditioning and refrigeration systems are commonly necessary to operate during cold temperatures. Server rooms, grocery stores and event spaces to name a few. When exposed to low ambient conditions, ACs and Heat Pumps condensing head pressure drops. If the head pressure gets too low, the system will not have enough pressure to operate properly and serious damage can occur including: Evaporator freeze-upsHydraulic lock-upsLiquid sluggingCompressor burnoutFan cyclingand moreThe solution is to install an ICM Head Pressure Control. The ICM325A low ambient head pressure control ensures the condenser fan runs at an optimal speed for maximum efficiency. If the system pressure gets too low or the condenser temperature gets too cold, the ICM325A lowers the fan speed accordingly. Other head pressure controls on the market just turn the fan off completely. This method results in inconsistent head pressure, inconsistent cooling, rattling pipes & ducts, system leaks, and ultimately a shortened life span of the condenser fan motor and compressor.SPECIFICATIONSOperates as temperature or pressure sensitive motor fan speed controlHelps prevent evaporator freeze-ups, low pressure cut-outs and liquid-slugged compressors in low ambient conditionsIntegral heat pump bypass circuitry allows electronic bypass of speed controlEliminates overshoots common to on/off and pressure switch controlsNear field communication (phone tap) using the ICM OMNI AppFeatures: hard start, low temperature bypass, isolated 24 VAC supplyControls up to 3 refrigeration circuitsRoHS compliant / lead free designTypical application: A/C and heat pumpsUniversal 120-600VAC line voltage and 24-240VAC control voltageINPUTLine input: 120-600 VACControl: 24-240 VAC (Jumper enabled)50/60 Hz 1.8 VA max.
