Mount the thermostat horizontally on the wall:

1. Pull the wires through the wire hole on the wallplate.

2. Position the wallplate on the wall with the arrow pointing 

up. Level the wallplate for appearance only.

3. Use a pencil to mark the mounting holes.

4. Remove the wallplate from the wall and drill two 3/16 in. 

holes in the wall (if drywall) as marked. For firmer 

material such as plaster, drill two 7/32 in. holes. Tap the 

wall anchors (provided) into the drilled holes until flush 

with the wall.

5. Pull the wires through the wire hole on the wallplate and 

position the wallplate over the wall anchors.

6. Insert the mounting screws into the wall anchors and 

tighten.

Disconnect power supply before connecting wiring.
