temp on high

[Reaper]

hello everyone great site I have an 03 Leisure Bay Harbor Cove, when I got it didnt work on temp up and the light 's. I read thru here about cable issues and found a small nick in it and used the proper crimper and everything seemed to work it can go into suspend and  set filter schedule, it seems that every works except that when on high speed the heater doesnt come on but you turn it on low it comes on and this lets the tub get cold while using  it. Is there any way to change this and is this normal? :-?

 Sounds like a amp problem if your on a 50 amp breaker you can if your spa allows it, install a 60amp breaker change a jumper or setting on the circuit board and the heater should work when every thing is on.

  Should say in your manual if its possible??

 If your running on 115v you cant do it.

The control system is set up so it will not heat on high speed. Look to see where your jumpers are set, compare it to the set up on the backside of the cover to the control pack. You should be able to heat on high if the jumper is set in the right place. It is normal.
