    carrier zone thermostats

    I have a building with an older Carrier zone system. Thermostats cat no.690040. These are the stats that have the rotary dial numbers 1-9 and letters A-F

    Problem that I am having is. I can not seem to set the set back temperature. I can set the over ride settings but once the over ride period is over it goes back to the set back temperatures.
    Does this have to be adjusted from the mother stat ? And then the zone stats ?

    Can not find any information online regarding these Carrier zone stats.

    You should have a monitor stat with a time clock. Check the date and time on that. Sounds like it is unoccupied. I cant seem to find the monitor stat manual, I will post it once I find it.
