From what it appears in the instructions, manual mode is automatically defaulted as "off" since most users won't use it. I don't see why I need it since I will be using this to either heat my sparge water, or be boiling. What is the advantage of manual mode?
Also, do I need to reverse the default operation of the PID to reverse action control the COOL mode to be in heating (6.14)?
