10 Check for any paint gaps or screw
holes left by the old thermostat.
If you choose to use the optional
Honeywell Decorative Cover Plate
and Standard Installation Adapter to
hide blemishes, snap the Connector
to Installation Adapter. For more
information see page 12.
11 Bundle and insert wires through
the new Honeywell Standard 16
Connector.
Gather the wires and guide them
through the hole in the middle of the
Standard 16 Connector.
Make sure at least 1/4-inch of each
wire is exposed for easy insertion
into the wire terminals. You can use
the “wiring guide” on the Standard
16 Connector door to measure the
correct length for exposed wire.
