    Delta GCL+ Cycle Timer

    Good afternoon,
    I am working on trying to program a cycle timer with ORCA... Trying to cycle pumps continuosly every 10 minutes during cold weather... 10 mins on and 10 mins off...
    I am not the Delta genius... I think I am close and can play around some more tomorrow... but wondering if any Delta pros can weigh in on this...

    For instance...
    IF OAT<45 THEN
    (PUMP = ON) AND (LOWTEMP = ON)
    END IF
    IF (PUMP = ON) ONFOR 10M
    (PUMP = OFF)
    END IF
    IF (LOWTEMP = ON) AND ((PUMP = OFF) OFFOR 10M) THEN
    (PUMP = ON)
    END IF
    IF (LOWTEMP = OFF)
    PUMP = OFF

    The tricky thing with the OnFor and OffFor is that they should really be called "True For" and "False For"
    So if you write the following:
    If (BV1 = Off) OffFor 5M then
    BV2 = On
    EndIf
    That is a double negative, it will execute when BV1 has been ON for 5 minutes.

    Also, when commanding multiple things within one If statement, just write to them on the next line. Using the AND operator asks a question it doesn't write to the point.

    Here's what you are looking to do:

    //ENABLE/DISABLE LOW TEMPERATURE MODE
    If OAT < 45 Then
    LOWTEMP = On
    End If
    If OAT > 50 Then
    LOWTEMP = Off
    End If

    //CYCLE PUMP ON 10 MIN INTERVALS WHEN LOW TEMP MODE IS ACTIVE
    If (LOWTEMP = On) And (PUMP OffFor 10M) Then
    PUMP = On
    End If
    If PUMP OnFor 10M Then
    PUMP = Off
    End If
