Hi All:
For those of you out there with Artesian Spas or Gecko Control packs, I accidently stumbled across how to unlock the temperature contols the other night for operation above 104 degrees. I own a 1999 Artesian Piper Glen
Set the tub up to 104, then press and hold down the temp up arrow. Keep holding for 7 seconds and an "r" will appear to the left and the numbers 05 up to 07 to the right. These represent temps of 105 through 107. If set above 104, the "r" will stay on the left. Using this, I can now maintain 108 with no jumpers or other tricks. Not good for warmer weather, but next winter will be a BLAST!
Peace and hot water....
