This is my first cold season with my new Dynasty spa. I noticed that the heater would not heat water when the pumps run on high speed. The two-flame indicator bar on the control panel blinks, and becomes solid as soon as I lower the pump speed.
The owner manual says "If your system in configured in Low Current Mode, the heater will not start if a pump is on at high speed".
Does anybody know what that means? Why would higher water flow affect the heater?
Could this mean that the electrician overlooked something during installation?
That is all.
