the wires from the wall.
(Some thermostats may have multiple covers, screws
or other locking devices that must be removed or
disengaged.)
3. Locate, but do not disconnect the wires.
(If wires are not visible, they may be connected to the back
of the wall plate. Some models may have doors that open
to expose the wires and mounting screws.)
