The status data in Table 46 displays first when the DHW
Hydronic heating loop is selected on the Home page. Scrolling
through the status groups eventually shows both.
The bar graph displayed for the CH control loop (hydronic) is
the outlet sensor temperature; for the DHW control loop it is
the DHW sensor temperature. When no analog DHW sensor is
installed (digital switch instead), the inlet sensor temperature is
displayed.
