Avoid a configuration warning after the firmware upgrade by disabling automatic setpoint switching. This makes sure the user's automatic setpoint configuration is not overwritten by the validity checks if the settings are not in the correct spots for the new configuration. Users will have to manually re-create the automatic setpoint switching configuration in the new format;
Add a checkbox to 'SPdeco' in the menu - this will make it obvious to users that this setpoint can be disabled. (mikeller)
