14. Checking components Note: 1) Don’t put a compressor on its side or turn over. 2) Please assemble the compressor in your air conditioner rapidly after removing the plugs. Don’t place the comp. in air for a long time. 3) Avoid compressor running in reverse caused by connecting electrical wire incorrectly. 4) Warning! In case AC voltage is impressed to compressor, the compressor performance will decrease because of its rotor magnetic force decreasing.

16. Control logic description 16.1 An illustration to outdoor unit signal (1) Communication between indoor and outdoor units: The communication between the outdoor unit, thermostat and the indoor unit is achieved through 24V alternating current, as shown in figure below. The thermostat controls the signal output of Y, if Y-C is high level, the outdoor unit starts in cooling mode.
16. Control logic description Compressor running rules: When the unit starts up in cooling mode, the compressor starts to work, and adjust its operating frequency according to the system target pressure and the actual pressure. If the actual pressure is higher than the target pressure, the compressor frequency will rise; if the actual pressure is lower than the target pressure, the compressor frequency decreases;...
16. Control logic description 16.5 Condenser High-temperature Protection DC-Inverter outdoor unit AC will enter T3 protection if any of the following conditions is satisfied. Cooling mode: When the saturation temperature (which is got from low pressure cycling) T2 keeps lower than TE5 for 120 seconds, the compressor and outdoor fan will shut off. When T2 is higher than TE6, the compressor and outdoor fan will restart up.
