Attach Wiring:
To insert a wire into a terminal, flip up the locking tab and
slide the wire into the socket directly above the corresponding label. Insert
each wire as required for the desired appliance. Once each wire is inserted,
flip the tab down to lock it in position. Pull gently on each wire after locking
the tab is closed to be sure the wire is secure.
A factory supplied jumper is supplied between RC and RH.
This should be removed in two transformer systems
(see Appendix A, page 16).
