    Metasys VMA not taking Set only Override

    Hi,

    Just switched over some 100 VMA's to N4 and for some reason the setpoints only take when overriding it. Set just sits there and doesn't update.

    It appears that you are dealing with n2. I don't believe that the default value priority used in bacnet will work in this application. Write at a different priority and I suspect you won't have any issues.

    vaultein,
    If this is an FX-60/70/80 you should select the "Slave Policy" for any point that needs persistent write/rewrite operation. Is it an FX JACE ?

    I am not sure but you may be able to un-hide the "Setpoint" on the slotsheet in N4 (FX-14). I do not recommend it as that function writes to EEPROM. Changing the tuning policy should solve your problem.
    If sense were so common everyone would have it !

    Any advice provided is worth exactly what you paid for it, not a penny more not, a penny less !!

    Cagey is right. The tuning policy is your answer.
