Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

This may not be a thermostat issue. Sometimes batteries that are low on charge or failing or have a bad ground lead this sort of issue. If the batteries are over 3 years old they should be load tested and the cables including the ground lead to the chassis should be cleaned at least once a year. I can get you the reset instructions, but you should check these things out as well. There is a good reason that this happens and voltage or lack of it is usually the cause.

Chances are good that if the batteries and cables checked out, that this thermostat bit the dust. It hasn't been made for some time and is NLA, but you can have it rebuilt. Probably best to upgrade to a newer thermostat and controls, but rebuilding may be less. If you want to try that let me know and I can supply some information on that service for you. All follow ups are included in our fee.
