    Carrier zone thermostats

    I need some info on a Carrier zone system. the thermostats were made by Parker Electronics for Carrier and the only model type I can find on the thermostat is VVT or VAVVT, and Electronic VAV.

    If you have the original Parker VVT that was produced for Carrier back in the 1980's that precedes Gen I, Gen II, etc. Those controls have not been available for some time. Its time for an upgrade.
    Effort is the 1st step towards failure.

    Pull the cover off and give me the chip number and I will help.
    Examples:
    33csvmt32 is Gen3
    mst16 is Gen2
    The gen ones have an oval cover with red ends.
    All of the above are now orphaned but parts are still available for some.
