The status data in Table 45 displays first when the DHW
Hydronic heating loop is selected on the Home page. Scrolling
through the status groups eventually shows both.

Table 45. DHW Hydronic Status. (Continued)
Data
DHW requested rate RPM or %
DHW sensor state None, Normal, Open, Shorted,
Outside high range, Outside low
range, Not reliable (None = no outlet
sensor)
DHW OFF setpoint Setpoint plus hysteresis
DHW setpoint Temp setting between -40 °F to 266 °F
(-40 °C to 130 °C)
DHW ON setpoint Setpoint minus hysteresis
DHW setpoint source Normal, TOD, Outdoor reset
DHW status Disabled, Normal, Suspended
DHW temperature DHW temperature (same as bar
graph)
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.
