If I start up my heater with a flow rate of ~60gpm (as displayed on the intelliflow) it will short cycle about every minute. If I reduce the flow to 40 the heater will stay on and after it is on for a few minutes I can dial up the flow back to 60gpm and it will continue to run and heat the pool. When it is short cycling I get no E codes or LEDs on the Igniter board or the back of the control board. The burner lights quickly and there is no rattling or odd noises. Filter is clean and am getting good flow. Pump @ 2500 = flow rate of ~60 back pressure is 22. I replaced the thermal regulator with a new one that I tested before install. The old regulator tested bad and the bypass valve is in place as best I can tell from feeling in the regulator port.
