9. Connect the CT to connector TB1 on the LCM

circuit board using customer-supplied wiring. See
Figure 7 and Figure 10.

10. Connect the controller interface connection to

4-position terminal block P10 on the LCM circuit
board. See Figure 7. See Section 2.4 for more
information about the interface connections.

11. Note the load priorities shown in Figure 8 and

connect loads accordingly. Also see Section 2 for
more wiring information and refer to the wiring
diagrams in Section 7.

Note:

Priority 1 is considered the most critical and
will add first and shed last. Priority 6 is
considered the least critical and will add last
and shed first.

a. If the LCM with terminal blocks is used, connect

load connections to the terminal blocks for
Loads A, B, C, and D.

b. If the pre-wired harness is used, connect the

loads to the harness.

See Figure 9 for the

harness connections.

12. Connect HVAC loads to TB3, if used. Note the

priorities of HVAC A and HVAC B relative to Loads
A through D. See Figure 8 and Section 3.3.

13. Write the names of the loads connected to each

relay on the decal for future reference.

For

example, Load A may be a sump pump, and
HVAC A may be the air conditioner. See Figure 10.

Note:

If the OnCue

System is used, the load descriptions in
