We have a Lux 1500 thermostat and it is locked. I can't unlock it and have tried a sequence to unlock it (up, down, next, hold, reset) and that doesn't work. A little lock shows on the screen and we can't adjust the temperature or make any adjustment.
Optional Information: Make : Lux Model : 1500Already Tried: Sequence: up, down, next, hold, reset in that order. Tried hitting the reset button while holding all four buttons down at the same time.
Have you pressed "next" 3 times and then "hold"?JACUSTOMER-dr1y8pvy- :That worked! I can now set the temperature. We are satisfied with the result.Billy :Excellent!
