EASY SELECT™ CONFIGURATION TAPS FOR 48XZ
Easy Select™ taps are used by the installer to configure a system.
The ECM motor uses the selected taps to modify its operation to
a pre-programmed table of airflows.
The unit must be configured to operate properly with system
components with which it is installed. To successfully configure a
basic system (see information printed on circuit board label located
next to select pins), move the 6 select wires to the pins which
match the components used (See Fig. 12).
