Setup Screen:
The Setup Screen allows access to five (5) other screens for 
adjusting control parameters. 
These screens are as follows:
  • Service / Setup - Allows access to change service 
    notification parameters, LCD backlight parameters, and 
 temperature units.
  • Setpoints - Allows access to change the HW set point 
    and ON/OFF differentials.
  •  Cascade - Allows access to change the cascade parameters.
  •  Night Setback - Allows access to change the date and time 
    and ON/OFF times for night setback. 
  • BMS - Allows access to change the 0 - 10Vdc BMS 
 parameters.
To change a parameter, press one of the five screen buttons.  
A list of parameters and their corresponding location are 
located on pages 10 and 11, Table 1B. Once a Screen button 
is pressed a list of adjustable parameters will appear. 
Select the parameter to be adjusted by pressing the SELECT 
button next to the parameter. The first time the parameters 
are accessed, you will be required to enter the service 
password. The service password is 5309. Using the keypad, 
enter the password and then press the OK button. If the 
password is not entered correctly, the screen will revert to the 
Parameter List Screen and you will not be able to adjust the 
parameters. If a digit has been entered incorrectly, press the 
left arrow key on the keypad to back up one digit. 
If the password has been entered correctly, the Parameter 
Change Screen will appear. The Parameter Change Screen will 
display the parameter being changed, the previous setting of the 
parameter, and adjustment buttons.
To adjust the parameter, press the + or - buttons to change the 
value being displayed. Once the parameter has been adjusted 
to the desired setting, press the APPLY button to change the 
parameter and return to the Parameter List Screen. If no change 
is necessary, press the BACK button to return to the Parameter 
List Screen. Once all the necessary adjustments have been 
made, press the BACK button to return to the Setup Screen.  
Repeat this procedure to adjust the parameters in other screens.
Press the SAVE button to program all changes made to the 
control parameters and return to the Status Screen. Leaving the 
Setup Screen without pressing the SAVE button will erase the 
changes made to the control parameters and revert them back 
to their previous settings.

the display. It is displayed in a 24 hour format. Reference the
