LM – Temperature Limit: This setting allows the maximum setpoint limit of the appliance to be set. The

maximum temperature for a residential model is 140 °F. To change the limit, access the SL menu, and set

the desired limit with the Up and Down buttons. You can also turn off the limit by selecting OF (off) in the

limit menu. Pressing the P button for 3 seconds will save the changes.

PE – Appliance Type: This menu allows changes to several options, including: appliance type, power, and

model. After initial setup, this menu should not be accessed.

PF – Bypass Activation: This menu allows the main bypass valve to be activated or deactivated. Normal

state is for this valve to be activated: allowing the bypass valve to function will let the appliance maintain

better temperature stability and overall optimized performance.

PA – Actuator Calibration: This menu controls access to the calibration of the two water valves. The main

valve controls overall water flow to the appliance: if water flow exceeds the heating capacity of the

appliance, the main valve will restrict water flow to allow the appliance to maintain temperature setpoint.

The Bypass valve allows colder inlet water to be blended with water from the heat exchanger, to create a

consistent outlet water temperature. Both calibrations require water to be flowing before beginning the

calibrations. Further details on the process of the calibrations can be found in this manual or the

Installation/Operation Manual.

IC – Ionization Correction: This menu controls the parameter for the ionization correction model. The

ionization control model is an auxiliary method for the appliance to determine air flow during operation.

Using this parameter allows greater reliability in operation. There are two different options for IC: on or off.

Default is on; there are no real applications where it would be beneficial for IC to be turned off. Ionization

control is a menu option in the P1 menu (see P1 menu table below); here it is default-set to off. Because

P1 is a manual calibration, it is best operating procedure to again leave the default setting.

E – Exit: This allows exiting from the main menu back to the home screen of the display. Scrolling to the

“E” option within the menu or submenu will always allow the user to move back to the previous menu.

P0 – L2 Gas Adjust: This menu allows for the verification of minimum power adjustment. There are two

different options for P0: on or off. The default setting is off. Again, it is best operating procedure to leave

the default setting.
