I pretty much have a similar problem but with a twist. My Intellicenter is connected to an Intelliflow VSF pump. When in auto I can tell the pool pump to come on and it can run all day, but as soon as I tell the MasterTemp 400 heater to come on, within 90 seconds the pump shuts itself off; the pump screen is switched from "Display Inactive" to 0 RPM where I can turn on the pump say Speed 3 in manual mode.
I can prove that it's not the heater tripping the pump but it is the other way around. I can put Intellicenter in Service mode, manually turn the pump on in Speed 3 running at 2400 RPM, and turn on heater and both will stay on for good. In manual mode, the heater does not trip at all and nor does the pump.
When it trips in Auto mode I do get a message saying MasterTemp Communication Lost with no pump alarms whatsoever, the only way to reset is to switch to Service and immediately back to Auto. Can Intellicenter detect some kind of low flow or high temperature sensing and shut the pump off in heating mode? The MasterTemp400 heater does not have any RS-485 smart hooked up to Intellicenter, it only has power and a 2-conductor wire terminated at the Fireman switch to come on and off based on external temperature sensor connected to Intellicenter so I don't see how the heater can tell the pump to shut down.
One weird thing is last week I backwashed the filter and put new DE in, the problem above went away, pump and heater came on in Auto like it should... but after I put in some No Phosphate stuff (advised by Leslie's Pool, which turned out to be a mistake), the problem came back.
The whole pool automation system is merely a year old so if there are defects they should be covered by Pentair. The only trouble is my Pool Builder is not very responsive so I may have to wrestle it through Pentair warranty myself. Any thoughts???
