Greetings, joined last year but this is first post. Since replacing primary pump (whisperflow 2hp) with intelliflow, pump consistently shuts off about 15 minutes into cycle when in spa mode with heater running. This does not appear to be temperature triggered as it occurs as throughout temp range as spa heats to desired setting. Pump is wired and controlled by aqua logic PS-8 same as whisperflow, which never presented this issue. Should pump be wired differently since it is variable speed? Both PS-8 and Raypak also have updated PCB's installed. This is getting old as I currently run to control panel every 15 minutes to turn pump back on when using spa.
