Communicating systems using the icomfort Wi-Fi
mostat wires between the thermostat and the furnace/air handler control and four
wires between the outdoor unit and the furnace/air handler control. When a ther­
mostat cable with more than four wires is used, the extra wires must be properly
connected to avoid electrical noise. The wires must not be left disconnected.
Use wire nuts to bundle the four unused wires at each end of the cable. A
single wire should then be connected to the indoor unit end of the wire bundle
and attached to the "C" terminals as shown in the diagram above.
