I just replaced my 13 year old Pentair Mastertemp 250 with a new MasterTemp 250.

What are the default VSP Pump settings needed here, specifically for "Spa" and "Spa Heat"

Background:
For the last couple of years I had issues with the heater shutting down when the JetPump was running and the heater turned on. We'd turn on the JetPump before getting in the tub, after the set point had been reached. The temperature would drop a little as the lines with cold water cleared, and the heater would fire back on, only to shut down a short while later with some service required message. I worked around it by increasing the speed for "Spa Heat" and then recently had cause to replace the heater due to other issues.
 
You have to experiment with different speed settings and see what works best for your pool setup. Every pool is different.

Now that you have a new heater I woudl try 2400 RPM for SPA HEAT and see if it works. If not increase it by 100 RPM at a time until you find the speed that works best.
