Thanks in advance for your help...
Issue
- I would like to alternate my return pump and my back up pump 23 hrs :1 hour ( I think I coded this ok)
- I would like to get alerts if my ReturnPump fails but not when it happens normally (This is where I am struggling. If I use the Flow meter (RtPump) or % output, or LowFlow (Virtual Outlet) as the alert it goes off when the pump switches over?
- Goals
- COR-20 (ReturnPump) to be on 23 hours In Normal Operation
- COR-15 (BackupPump) to be on 1 hour in Normal Operation
- I would like the COR-15 to automatically turn on if the COR-20 fails or is off (I can turn off manually at Maintenance time.
- In a Power Outage I would like them to work the same way i.e. backup comes on if the primary is off...but at a reduced speed which is in the Profile COR_Slow)
Nomenclature
- RtPump is 1” Flow meter Normal operation is about 450 gph. This is on the COR-20 not the COR-15 (I might be able add an additional flow meter or re-plumb for this to be on the return line n the future??
- LowFlow is virtual outlet
- ReturnPump is COR-20 and has 1: flow meter
- BackupPump is COR-15 has separate return line to the tank no flow meter.
- OVRFLO is an optical switch on my mesh in case it starts to overflow
- LeakCA and LeakFL are leak detectors in cabinet and on floor
- COR_Slow is a ramp profile to run at 25% flow of the COR 15+20 Pumps (I presume I can use one profile)
LowFlow- Virtual Outlet ?????
Set OFF
If RtPump < 100 Then ON
If Output ReturnPump Percent < 25 Then OFF
Defer 000:10 Then ON
Defer 000:05 Then OFF
When On > 000:02 Then ON
ReturnPump
If Power Apex OFF 001 Then COR_Slow
If Time 23:00 to 23:59 Then OFF
If FeedA 001 Then 40
If OVRFLO CLOSED Then 0
If Output LowFlow = ON Then OFF
If Error ReturnPump Then OFF
BackupPump
If Power Apex OFF 001 Then COR_Slow
If FeedA 005 Then 1
If OVRFLO CLOSED Then 0
If LeakCa CLOSED Then 0
If LeakFL CLOSED Then 0
If Output ReturnPump = OFF Then 100
If Output ReturnPump = ON Then OFF
Thanks again and I am open to other simplifications...
