My spa heater has consistently read 2-3 degrees higher than the spa. This is true whether the unit is heating or not. I have verified the spa temperature multiple ways (Jandy system probe, external analog thermometer, temperature reading on salt meter). I changed the temperature probe (009577F)
in the heater today but it did not improve or change the miscalibration. The main board has been changed 3 times in the past year and the temperature reading has consistently been off. I expected the new probe to fix the problem ,but it did not. Any ideas for a solution? I must override the high limit on the spa heater and set to 106 in order to heat my spa to 104. Been this way for at least 6 years on a 10 year old heater.
