Using either a small, thin screwdriver or a thin drill bit, make holes in the wall where you marked the spot for the screws and insert screw wall anchors for a safe installation of your new thermostat. Make sure the anchors are installed flush to the wall.
Step 6 – Slide Wires Through and Secure Plate
Pull the wires through the holes in the back of the minting plate and then attach it to the wall with screws inserted into the wall anchors. Makes sure the mounting plate is level.
