1. Safety
NOTE: Use 18-gauge color-coded thermostat cable for
proper wiring. Shielded cable is not typically required.
Keep this wiring at least one foot away from large inductive
loads such as Electronic Air Cleaners, motors, line starters,
lighting ballasts and large distribution panels.
Failure to follow these wiring practices may introduce
electrical interference (noise) which can cause erratic
system operation.
All unused thermostat wire to be grounded at indoor unit
chassis ground only. Shielded cable may be required if the
above wiring guidelines cannot be met. Ground only one
end of the shield to the system chassis.
