Help! Ranco temperature control has E2 message

[Forty-Reefic]

My tank temperature went up to 92 degrees!!! From the usual 77, pump ok, chiller ok, everything checked out and it started cooling.... 92, 90,88,85, then 82 oops! E2 not 82
I looked up ranco and it says:
" Appears if the control settings are not properly stored in memory"
I can't change it, dealer can't get another controller till tuesday,
any ideas???
How do I know its the controller???


Tank: 210 gallons, one year old on jan of this year
was very stable and finally doing great

Sorry, I don't know anything about that controller. You could run the heaters without it, if you have standard heaters. I'd disconnect the controller, if it were from my system. How high does the tank temperature get the chiller? Can you point some fans at the water surface?
