This section outlines the procedures to: 1. Connect a gauge set for testing and charging as illustrated in fig­ure 55. 2. Check and adjust indoor…

The Y terminal located on the outdoor control allows the outdoor unit to be cycled ON and OFF using 24VAC inputs. The outdoor unit will…

OPERATION OF COMPONENTS: Electromagnetic compatibility circuit (EMC): EMC ensures the correct operation of different equipment items which use or respond to electromagnetic phenomena. It also…

OPERATION Pins 5 and 6 (No Sensor) There is no sensor located on positions 5 and 6 of the connector. A resistor installed between pins…

OPERATION: The outdoor control is a microprocessor-based device for use with variable-capacity compressors up to 5-tons in capacity operating on 24VAC residential power. The outdoor…

Electronic cabling and wires, by virtue of their length­to­width ratios, are perfect natural antennas. In the presence of high­speed microprocessor signals, cables will conduct, radiate,…

OPERATION: These units use an integrated control and motor that is programmed for variable-capacity operation. The fan speed is controlled by the iComfort Wi-Fi® thermostat.…

OPERATION: The line filter reduces the unintentional conducted emission from the equipment, to a level sufficient to pass regulatory limits (such as FCC part 15).…

OPERATION: Reactor (Inductor or choke) is a passive two­terminal electrical component that stores energy in its magnetic field. Reactors are one of the basic components…

OPERATION: Top Cap Thermal Sensor Switch (S173) Some units are equipped with a compressor-mounted normally closed temperature switch that prevents compressor dam­age due to overheating…
