Patent attributes
A thermostat is provided that includes a lock disposed in a sub-base, which includes a cam coupled to the lock to permit rotation of the cam between an unlocked and a locked position. The cam includes an offset portion that is configured to rotate over a vertical retaining portion of the thermostat housing, to retain the thermostat housing to the sub-base. The cam further includes an outwardly extending portion, wherein the outwardly extending portion is configured to rotate adjacent to a door that is pivotally coupled to the thermostat housing. When the cam is in the locking position, pivoting of the door is impeded by the outwardly extending portion of the cam, to resist pivotal movement of the door and thereby inhibit access to one or more input means or controls of the thermostat.
