5) TO INSTALL NEW THERMOSTAT
1. Mount the thermostat on an inside wall about
five feet above the floor in an area that has good
circulation, but is not directly aected by a vent
or duct.
2. If painting or construction is still ongoing, cover
the thermostat completely or wait until work is
complete before mounting thermostat.
3. If new mounting holes are needed, mark the
placement of the new mounting holes through
the thermostat base. Using a 3/16" drill bit,
drill the holes you have marked and insert the
supplied wall anchors.
4. Feed the wires through the wire opening in the
base and use supplied screws to mount base to
the wall.
5. Using Section 7) WIRING DIAGRAMS, wire each
terminal on the new thermostat base. Ensure that
the bare end is fully seated into the connector,
then tighten securely. Pull gently on wires to
ensure they are secure.
6. Place thermostat front back onto the base.
7. Restore power back to heating and cooling
components and thermostat.
8. See Section 8) INSTALLER SETTINGS MENU, to
adjust the required settings needed for each
system type.
