Mounting The Thermostat Back-Cover
The back-cover should be mounted horizontally
with the terminals on the left side.
Thread the existing wiring through the big center
hole from the back and set the back-cover
horizontally on the wall.
Select two appropriate mounting holes and mark
the locations with a pencil. If necessary, use a level
to make sure the thermostat is leveled.
Remove the back-cover from the wall and drill two
3/16 inch holes in the marked screw positions.
Insert the wall-anchors into the holes completely. If
necessary, use a hammer to tap-in lightly.
Mount the back-cover with the two screws to the
wall. Make sure the metal terminals are on the left
side.
