Overriding Temp. Settings

[STELPE]

Good Morning,

I bought a 1997 Coleman 447 used. We have repaired, filled and are enjoying our spa but wonder if anyone knows how to override the factory setting which does not allow the tub to be set higher than for a temperature of 104. We would like to get a few more degrees out of our tub. The manual does not offer information on an override. Any help would be appreciated.

Thanks

The manual does not offer info because they don't want you to exceed 104 F. However, you can gain a few degrees by adding resistance in series with each sensor. Use the same size resistors on each sensor. Try a 2.2 KOhm 5 percent tolerance type. Remember though, you are fooling the electronics, so the actually temp reading will not be accurate. You might set it for 104, but actually attain 107.

thanks!!!...............we are only looking for a few more degrees anyway, will try this and see if it helps.

increasing the filter cycles will also bump it up a few degrees, but you will run the pump longer
