*    Table 11 illustrates the complete hierarchy. The menu parameters 

may be different depending on the configuration. For example, if 
there is no DCV (CO

2

) sensor, then none of the DCV parameters 

appear.

†    When values are displayed, pressing and holding the

 

 

or

 

 

button 

causes the display to automatically increment.

**   N/A = Not Applicable.
††   ERV Operation: When in cooling mode AND the conditions are 

NOT OK for economizing - the ERV terminal will be energized. In 
the Heating mode, the ERV terminal will be energized when the OA 
is below the ERV OAT setpoint in the setpoint menu.

Checkout Tests

Use the Checkout menu (see Table 11) to test the damper

operation and any configured outputs. Only items that are

configured are shown in the Checkout menu.
NOTE: See User Interface for information about menu naviga-

tion and use of the keypad.
1. To perform a Checkout test: 
2. Scroll to the desired test in the Checkout menu using the

 and 

 buttons. 

3. Press the 

 button to select the item. 

4. RUN? appears. 
5. Press the 

 button to start the test. 

6. The unit pauses and then displays IN PROGRESS. 
7. When the test is complete, DONE appears. 
8. When all desired parameters have been tested, press the

 (Menu up) button to end the test.

Checkout test can be performed at any time during the op-

eration of the system as a test that the system is operable.
