Description/Action Display
Access Code - Displays access code utilized to enable/disable
screen lock.
Enable Screen Lock - Factory default set to No. When enabled,
prevents access to any screen but the home screen and the
Contact Information screen. This feature restricts access code to
secure the water heater.
Calibration Mode - Used by service agent to adjust the gas valve
for minimum and maximum fire rate.
Calibration Speed - Used by service agents to adjust blower speed
to minimum fire rate if required.
Note: Calibration mode will reset back to No when the contact
information screen is exited either by pressing the Back
button or when the display times out. To be practical, the
installer/field service agent should first go to the Display
Setting screen from the Main Menu and set the Backlight
Delay to 240 (On) before setting Calibration mode.
