Andy I saw your post on David's thread. I set my MP60s and MP40s like the program Dan was using with a few differences because I received the same error response as you did. I eliminated "Set Pulse" as an initial command. Further, I set up specific pump profiles for TS, RC, and Lagoon and labeled each for each pump i.e. TS-1, TS-2, etc. My MP60 on the right became the master pump and the other 3 slaves. I then set up a profile for Anti-sync which can run all three slaves. Alternatively, you can set up Sync as a separate profile for the slaves and get the same result.
So my outlet for my master is:
Fallback ON
If Time 08:01 to 10:00 Then TS-1
If Time 10:01 to 12:00 Then RC-1
If Time 12:01 to 14:00 Then RC-1
If Time 14:01 to 16:00 Then LG-1
If Time 16:01 to 18:00 Then RC-1
If Time 18:01 to 20:00 Then RC-1
If Time 20:01 to 22:00 Then TS-1
If Time 22:01 to 08:00 Then LG-1
The slaves have similar commands with Antisync used in place of the second RC line. I used specific pump profiles instead of sync to give more variability. And I use a low speed Lagoon for night time. Good luck.
