How Do I Unlatch A Honeywell Ct3300 Thermostat From Its Wall Plate?
The manual seems to indicate that the latch is on the bottom of the unit but I can't find it, even through probing with a small screwdriver. Strangely, the manual shows how to mount the unit but not how to remove it! What have I missed
