On those models, pull evenly along the sides and bottom of the thermostat to separate it from the wallplate. - Mount wallplate as

Mount new wallplate using screws and anchors included with the thermostat. Drill 3/16-in holes for drywall. Drill 7/32-in holes for plaster. - Wire the
thermostat
Refer to the table and wiring diagrams on the next page.
a) Turn on 24VAC NOW. 24VAC (C wire) is required. - Mount thermostat on
wallplate
If your thermostat has hinges along the bottom and a button on the top, align the thermostat at the bottom and snap into place as shown. If you have the version without hinges, line the thermostat up evenly with the wallplate and push the thermostat evenly along the sides and bottom to snap it into place.
Performing installer setup
Setup options define the type of system you are installing and preferences for the display.
When newly installed, the thermostat goes into intstaller setup when first powered. If re-entering installer setup at a later time, go to menu, installer options, and enter the passcode (shown on page 2).

** The THP9045A1098 C-wire adaptor is used on heat/cool systems when you only have four wires at the thermostat and you need a fifth wire for a common wire. Use the K terminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire–the unused wire then becomes your common wire. See THP9045 instructions for more information.
