2G. CONFIGURATION
The Comfort Control Center configuration relates to setting
the Dip switches and particular components (remote tempera-
ture sensor, cold [freeze] control and ambient sensor) that can
be plugged into the AC power module board according to the
type of unit and accessories included.
NOTE: If the configuration of the Dip switches and plug-in
components are not correct, the air conditioner or heat pump
could operate erratically or not operate at all.
Improper configuration could cause damage to com-
ponents of the system.
We recommend the configuration be done at the time of
installation by the installer.
To check the configuration, first locate the Electronic Control
Kit on roof-mounted units or the Electronic Control Box on
basement mounted units. Next remove any cover or covers for
access to Dip switches and Sensor Plugs (P3, P4 and P5).
Both are located on the AC Power Module Board. All Dip
switches are in the "OFF" position at the time of manufacture
of the appliance.
NOTE: The only exceptions are Models 620315.XXX,
39424.XXX and 39224.XXX.
If the configuration is not correct, turn Comfort Control
Center OFF before changing the configuration.
