DIAGNOSTIC DISPLAY

By simultaneously pressing the “Mode” and “down arrow” buttons for 3 seconds the unit will allow access to the diagnostic mode.

In diagnostic mode, using the up/down arrow allows for cycling between diagnostic codes. The numeric display will show the diagnostic code for 1 second, followed by the actual measurement displayed for 3 seconds. For example, H01

-105 represents the diagnostic code of “H01” and the value of “105” is the inlet water temperature measurement. The display will continue to show the diagnostic code and the measurement value unless the up or down arrows are pressed to switch to the next item (see Table 4). If no buttons are pressed for 30 seconds the unit will revert back to operation mode where the set-point temperature is displayed.
