JACKVJR Posted March 9, 2018 Report Share Posted March 9, 2018 Greetings, We have a 2005 Caldera Kauai and enjoy it every night. One of the best features of the older models is the +1UT and +2UT functions. This means they can maintain 105 degrees or 106 degrees. We feel the difference and would not like to lose the ability to choose those temps. Having said this, we're having some issues with the unit holding constant temperature Sometimes it drifts down.. One suggestion was it may be a heater relay control board problem. We'd spend the money for a replacement in a minute, but are concerned any new control board may have the safety nazi 104 limit built in. Does anyone have any experience with this and can speak from experience? jack vines Quote Link to comment Share on other sites More sharing options...
