i have a cal spa hot tub. what does it aim when the LED screen blinks "EC" ??
Answers: EC does stand for cutback mode. That means it onle heat when it goes through it's filter cycle. The pumps do not be in motion into a reduced state of operation. It of course beyond doubt is safe to use. By the route I sold Cal Spas and now do warranty repair for them.
I estimate the "EC" refers to "Economy Mode" where the pumps do not work at full speed adjectives of the time.
