1. Changing the HIGH/LOW shutdown temperature can void the warranty of the DSATX - because it can be forced to run too hot and then die. Perhaps put a lock on these values or hide them. So a user can only change them if they REALLY need to.
2. TEMPLOWSIGN (ID_20) is just a + or - sign for TEMPLOW (ID_18). Perhaps hide this variable to the end user, but change the variable on the DS-ATX depending on the users TEMPLOW value. No real point getting them to click +/-, might aswell change the sign via code, as the user scrolls past "+... 0 ....-" degrees and back the other way.
Just throwing some ideas out.
