  • Page 29: Microprocessor Control

    MICROPROCESSOR CONTROL 1. COOLING/HEATING OPERATION Outdoor unit operation is activated by delivery of a 12VDC signal from the indoor unit. Cooling only units have 2 low voltage control wires from the indoor unit to the outdoor unit. Heat pump units have 3 low voltage control wires from the indoor to the outdoor unit.
  • Page 30 MICROPROCESSOR CONTROL 3. OUTDOOR BOARD FUNCTIONALITY A. High Pressure Safety Switch (HPSS). Opens at approx 420 PSIG and closes at approx 320 PSIG. There is no bypass on this switch. When the switch opens it immediately stops the compressor and outdoor fan. When it closes the system can restart providing the indoor unit has not entered a P8 fault code.
  • Page 31 MICROPROCESSOR CONTROL J. Line Voltage. Line voltage is input and output from the circuit board on the terminals marked “L1” and “L2”. There are four terminals marked “L1”, the purpose of each is as follows. One is “L1” input to the board while the remaining three are outputs to one side of the Transformer, Crankcase Heater and the Outdoor Fan Motor.
