programming instructions for the specific panel.

switch, “Fan” selection switch, and “Zone
Temperature” settings for automatic operation are
correct.

switch that provides the supply power to the unit’s
terminal block or the unit mounted disconnect switch.
Make sure all personnel are standing clear of the unit
before proceeding. The system components will start
when the power is applied.
