    RTAA ice build complete

    I have an RTAA that when commanded to start ice build mode immediately goes to ice build complete. My entering and leaving temps are well above set point so it's not a sensor problem. HELP!

    your contacts that INITIATE ice building are opening after they close. I would recommend that you investigate the BAS that is controlling this feature. take a jumper and...wait...investigate first.

    any diagnostics?

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    He said in post #5 that "chiller has no alarms", but people unfamiliar with this panel have been known to get confused on how to check for current alarms and alarm history. Come to think of it, so have people who are (supposed to be) familiar with it.
