Remove the cover plate of the old existing thermostat. Using the tags provided, mark the individual wires to match what's on the circuit board. This will ensure that the wires go to the right place when installing the new thermostat. Once all the wires are properly labeled, free them from the old contacts.
With the wires disconnected, remove the back plate. Put the new back plate in place. If the anchors don't match up it may be necessary to drill new holes. Re-attach the wires. Note: Refer to the manufacturer's instructions to ensure proper configuration. Attach the control panel and put the new faceplate in place. Test the thermostat.
