and ON/OFF times for night setback.

To change a parameter, press one of the seven screen buttons.
A list of parameters and their corresponding location are
located on pages 11 and 12, 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

left arrow key on the keypad to back the digit up.
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 further
changes are 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
