I accidentally plugged my ozonator in where the pump was supposed to be on my new balboa control board and was seeing temps. as high as 109 when set to 104. A 5 deg.difference! Consistantly. I needed a new pump after needing a new circuit board and realized my mistake when removing the failed pump. Yesterday i hooked up my new pump and correctly wired the circuit board and now find that 100 means 100 deg. In my mistaken circuit board wiiring my topside control board only worked on High with the lights on. I have a Viking 500 gal. Litel Leader. (17 to 20 years old)My neighbor gave it to me for free as long as i moved it out of his back yard. That "FREE" hot tub has now cost me, at least $1000.00 + 2000 for me to build a cedar deck and electrical connections. However if i don't encounter anymore upgrades it will have been worth it! Please let me know if my mistake is a repeatable non burnout workaround for achieving higher than standard temps.
