22.1.7
NIGHT SETBACK OVERRIDE
Any Night Setback On trigger currently active or scheduled within the next seven (7) days can be skipped. To skip a trigger, go to
the Night Setback Status Screen and press the SKIP button. Rotate the NAVIGATION dial until the arrow (>) is next to the trigger
you wish to skip. Press the NAVIGATION dial once. "SK" will appear next to that trigger to indicate that it will be skipped. You can
restore an upcoming trigger by selecting that trigger, and pressing the NAVIGATION dial again. The "SK" next to that trigger will
disappear.
To save any changes and return to the Home Screen, press the RIGHT SELECT [HOME] key. To return to the Status Screen without
saving the changes, press the LEFT SELECT [EXIT] key.
22.1.8
DISPLAY TIMEOUT
This is the time in which the display remains illuminated. The range is 10 seconds to 10 minutes. The default is 10 minutes.
22.1.9
DISPLAY CONTRAST
The contrast of the LCD display can be adjusted to improve readability. The contrast is adjusted automatically when the display
board is tested at the factory, but different ambient conditions may warrant changing the setting. This parameter can be changed by
accessing the Display Contrast setting. The range of this parameter is -10 to +10. The default setting is 0.

DATA LOGGING

22.2.1
RESET LOG ERRORS
The reset log errors function clears the last 10 errors log.

FUNCTIONS

22.3.1
SERVICE MODE DELAY
By pressing the pin button on the front of the display for five (5) seconds, the control will be placed in Service Mode. This will
override all other heat demands. The Service Mode allows the installer to set the unit to any firing rate for the purpose of
combustion analysis. The delay sets the length of time the water heater will stay in the Service Mode if no keys have been pressed
before going back to its original state. This parameter can only be changed by the installer by accessing the Service Mode Delay
parameter. The time range of this parameter is 1 to 10 minutes. The default value is 10 minutes.
22.3.2
FREEZE PROTECTION PUMP ON
The SMART SYSTEM control will turn on the water heater and system pump outputs whenever the inlet temperature drops below
this setting. This is done to prevent the water in the heat exchanger from freezing. Certain low temperature applications (such as
snow melt) can operate at temperatures around freezing, so this setting needs to be lowered in these cases. The installer can
adjust the temperature at which the pump outputs are turned on by accessing the Freeze Protection Pump On parameter. The
minimum setting is -19°C, and the maximum setting is 7.2°C. The default setting is 7.2°C.
22.3.3
FREEZE PROTECTION BURNER ON
If running the pumps does not prevent the inlet temperature from falling closer to freezing, the SMART SYSTEM control will fire the
burner at low fire. The installer can adjust the temperature at which the burner fires by adjusting the Freeze Protection Burner On
parameter. The minimum setting is -19°C, and the maximum setting is the Freeze Protection Pump On parameter. The default
setting is 2.8°C.
22.3.4
FREEZE PROTECTION BURNER DIFFERENTIAL
Once the burner has started firing due to a low inlet temperature, the inlet temperature must increase by this amount before
the burner turns back off. The installer can adjust this differential by accessing the Freeze Protection Burner Differential parameter.
The minimum setting is 0°, and the maximum is 11°C. The default setting is 2.8°C.
