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.
