    Chiller timer programming help

    I'm trying to set the chiller outlet on a timer but having trouble how to properly word the programming. Schedule should be -

    Sunday 830PM to 11:59PM OFF
    Monday 12AM to 730AM OFF
    Tuesday 830PM to 11:59PM OFF
    Wednesday 12AM to 730AM OFF
    Thursday ON
    Friday ON
    Saturday ON

    This is the current code I'm using but I don't think it's correct
    Fallback ON
    If Tmp > 76.1 Then ON
    If Tmp < 75.9 Then OFF
    If DoW S-T---- Then OFF
    If Time 07:30 to 20:30 Then ON

    Any help would be appreciated.

    That's gonna take a slew of virtual outlets to pull off. Why would you want to do that? I don't understand what value that adds.

    Tank & Chiller is right by child's bed and chiller noise is too loud during sleep time.

    Then you want this

    ChillOFF1
    Set OFF
    If Time 20:30 to 23:59 Then ON
    If DOW -M-WTFS Then OFF

    ChillOFF2
    Set OFF
    If Time 00:00 to 07:30 Then ON
    If DOW S-T-TFS Then OFF

    Chiller
    Fallback ON
    If Tmp > 76.1 Then ON
    If Tmp < 75.9 Then OFF
    If Output ChillOFF1 = ON Then OFF
    If Output ChillOFF2 = ON Then OFF

    Apologies in advance but I'm not familiar with virtual outlets at all. Are ChillOFF1 / ChillOFF2 command entered into virtual outlets that have to be created? Or do I paste the code in entirety to Chiller outlet programming?

    Also, shouldn't it be

    ChillOFF1
    Set OFF
    If Time 20:30 to 23:59 Then OFF
    If DOW -M-WTFS Then ON

    ChillOFF2
    Set OFF
    If Time 00:00 to 07:30 Then OFF
    If DOW S-T-TFS Then ON

    Since I need the chiller to be OFF 20:30 to 20:59 on Sunday & Monday and 00:00 to 7:30 Monday & Tuesday?

    ChillOFF1 and 2 are virtual outlets. Only the code underneath chiller goes into the physical outlet.

    The way I have described the VOs is correct. The apex evaluates programming from the top to the bottom, where the last true line wins. The way you showed chillOFF1 in your response would be ON all day Sunday and Tuesday and off all other times.

    Ah, I understand now. Just created two VOs and applied your codes to all three outlets, will check tonight and report back if there are any issues.

    Do I need to assign the two VOs to the physical outlet somehow so it knows to correspond with the chiller outlet or is that already assumed based on code added in physical outlet? In other words, are ChillOFF1 / ChillOFF2 essentially simply acting as timers and Chiller outlet simply abiding by the timer set in those two outlets?

    The if outlet statements are how they got associated.

    Worked perfectly, thank you for your help!

    My network connection can be finicky and I lose connection to fusion sometimes. Should I set the chiller Fallback to OFF or will the outlet still obey the commands even with no fusion connection?

    Fallback is a loss of connection between the base unit and the energy bar. It could care less if you have access to fusion or not.

    The choice of ON vs OFF is a personal choice on whether you would rather have it run per it's own thermostat in the apex stops controlling it or whether you would rather have if OFF.
