  1. Separate the wallplate from the thermostat as shown.honeywell rth7500d installation
  2. Pass the labeled wires through the wire hole on the wallplate.honeywell rth7500d installation
  3. Position the wallplate on the wall with the arrow pointing up. Level the wallplate (for appearance only) and mark the two mounting holes with a pencil.honeywell rth7500d installation
  4. Move the wallplate aside and drill holes at the locations marked on the wall. Drill 3/16 in. holes for drywall or 7/32 in. holes for plaster.
  5. Tap the wall anchors into the drilled holes until even with the wall surface.honeywell rth7500d installation
