I have a new back heat rack.
I'm getting perfect hot side temps of 88-90. However, my cool side temps started out as 80 and keeps increasing. It's currently 84.
How can I regulate this back to more ideal temps?
I'm using a ranco thermostat on 11'' flexwatt. (Planning to upgrade to a herpstat soon)
The thermostat probe is on the middle shelf between the tub and the flexwatt.
