Hello. I have a pentair mastertemp 400 heater and we recently had some electrical work done and the pool equipment breakers were all shut off. This caused the heater to reset to the default settings and now we can't get the spa over 100 degrees. I read a lot of the advice on the forum and know I need to reset the temp by pressing the yellow button on the control board under the cover. I followed the instructions in the manual but the display doesn't turn on when I press the yellow button and I have no way of raising the max temperature.
There is an iaqualink controller installed as well and I understand there may be something I need to do with the firemans switch wiring to engage the yellow button to reset the temp but I don't know exactly what that is. Does anyone have any advice on this and what I need to do to get that yellow button to work?
Thanks in advance!
