Page 12: Electronic Control Board Mode Of Operation
Switch closure and fan operation occurs when the pressure reaches 400 PSIG. The switch opens again when the refrigerant pressure falls to 245 PSIG. Therefore, the outdoor fan always starts after the compressor, and it will cycle frequently during normal operation at low outdoor conditions. ICE SlimPac ECUA12-18 I&O Manual 03/2019 Rev.2... -
