This is the 2016 Manual for SP3.0 as an update from the previous 2015 Manual for SP2.3. The main difference is the Controller operation is slightly simpler and the explanations are more clear. Download for your reference.
The 2017 SP3.1 Owners Manual has substantial updates that make the Controller and Operations much easier to follow, It is recommended for SP3.0 Owners as well because the controller and operations are the same.
*** NOTE *** The hot water sensor must be located in the bottom well, behind the front panel. It will not function right in the top well, so please check to avoid odd heating behavior. See Sensors article.
