The status data in Table 25 displays first when the DHW
heating loop is selected on the Home page. Scrolling through
the status groups eventually shows both.

DHW demand request status is reported by the 833-3639.
Expected 833-3639 implementation depends on DHW
demand source. When DHW demand source is Switch,
833-3639 reports digital status (no matter what has current
demand priority). When DHW demand source is Sensor,
833-3639 reports “Yes”; when DHW temperature is
between DHW setpoint - hysteresis On and DHW setpoint
+ hysteresis Off, otherwise it reports “No.”
The bar graph displayed for the CH control loop 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.
