Here's my scenario:
I have a Reeflo Orca 250 skimmer on my 280g reef. It is fed by a DC pump that is controlled by a VDM outlet for a "really really soft start".
The basic idea is this: until the skimmer has filled up, it hasn't created enough hydraulic head pressure to drain fast enough back into the sump, and it can fill a 5g bucket to full within seconds.
So I have a virtual outlet that waits 1 minute after the skimmer pump turns on. When that timer output is OFF, the pump is set to 30% (minimum). Then after 1 minute, it switches to ramp, and ramps up to the run setting.
If I manually turn the skimmer pump off and on, this works great.
But if there is a power fail, or the Apex reboots, both outlets immediately switch back to ON, and the bucket fills.
Here is the current programming:
Physical outlet for skimmer feed pump ("Skimmer_3_5"):
Fallback OFF
Set ON
If Power Apex Off 000 Then OFF
Min Time 001:00 Then OFF
If Output SkimmateFull = ON Then OFF
(SkimmateFull is the bucket full sensor)
Virtual outlet "STimer1" (for "Skimmer Timer"):
Fallback OFF
Set OFF
If Output Skimmer_3_5 = ON Then ON
Defer 001:00 Then ON
And the VDM port ("base_Var4"):
Fallback ON
If Output STimer1 = OFF Then 30
If Output STimer1 = ON Then SkimmerRamp
If Output Skimmer_3_5 = OFF Then OFF
The scenario works if I turn the "Skimmer_3_5" off and on; but not for an Apex reboot.
Thanks very much for any thoughts!
