Note:
In operating mode, holding either the ↑ or ↓ button while viewing a given parameter will keep
the display on the actual reading. For example, pressing ↑ while reading boiler temperature as
shown in Figure 11.4 will keep the display on 180 for as long as the button is held. This makes it
easier to view readings "live" if they are changing rapidly.
