Unused wires
Communicating systems using the icomfort Wi-Fi
thermostat 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 thermostat 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 above.
