This board manages the defrost cycle by combining time and temperature inputs to determine when defrost is needed and when to terminate it. HVAC technicians rely on defrost control boards like the ICM322 to keep heat pump systems running efficiently in cold weather. Without proper defrost control, ice builds up on the outdoor coil, reducing heat transfer and system efficiency. The ICM322 solves this with a fixed 10-minute defrost time and pin-selectable intervals of 30, 50, or 90 minutes between defrost cycles, giving technicians flexibility to match the board to the specific system requirements on the job. The board operates on 18 to 30 VAC at 50 to 60 Hz and draws a maximum of 1 watt, making it an energy-efficient control solution. High-power relay outputs support an outdoor fan rated at 1\/2 HP at 240 VAC, as well as strip heat and reversing valve outputs at 24 VAC and 1 amp. Output relays include a DPST normally open relay rated at 1 amp at 30 VAC, with a normally open contact rated at 20 amps and a normally closed contact rated at 10 amps. A built-in test pin feature reduces test time by a factor of 256, saving technicians significant time during commissioning and troubleshooting. The board powers on with a 500-millisecond reset time. It is a direct replacement for the Carrier CES0130024-00 defrost timer, making it a straightforward drop-in solution for service calls involving Carrier heat pump equipment. The ICM322 is a practical, cost-effective choice for defrost board replacement, heat pump repair, and HVAC preventive maintenance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirect replacement for Carrier CES0130024-00 defrost control board\u003c\/li\u003e\n\u003cli\u003ePin-selectable defrost intervals of 30, 50, or 90 minutes with fixed 10-minute defrost time\u003c\/li\u003e\n\u003cli\u003eBuilt-in test pins reduce test time by 256x for faster commissioning and troubleshooting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe ICM Controls ICM322 delivers reliable time and temperature defrost control for heat pumps at a low cost, with flexible interval settings and high-power relay outputs suited for standard residential and light commercial applications.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ICM CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: icm322\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 18\/30 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50-60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption\u003c\/strong\u003e: 1 watt maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: O, W2, T1, T2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Form\u003c\/strong\u003e: DPST normally open, SPST normally open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Rating\u003c\/strong\u003e: 1 amp at 30 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNormally Open Contact Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNormally Closed Contact Rating\u003c\/strong\u003e: 10 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDefrost Time\u003c\/strong\u003e: Fixed 10 minutes, plus or minus 5 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterval Time Between Defrosts\u003c\/strong\u003e: Pin-selectable 30, 50, or 90 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower On Reset Time\u003c\/strong\u003e: 500 milliseconds\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ICM CONTROLS","offers":[{"title":"Default Title","offer_id":51120890741042,"sku":"ICM322","price":45.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304886525.jpg?v=1777742521","url":"https:\/\/voomisupply.com\/products\/icm-controls-icm322-ultra-low-cost-heat-pump-defrost-timer-30-50-90-min-intervals-replacement-ces0130024-00","provider":"Voomi Supply","version":"1.0","type":"link"}
