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 wires should 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.
