Step Test
The step test systematically verifies that key components of the system are operating as expected. Note
the following considerations:
• The stages in the step test can be executed in any order; they do not need to be sequential.
• The Step Test takes the system out of automatic mode.
To perform the step test, follow these steps:
1. Hold Esc until the main screen is displayed.
2. From the Main Screen, press Prg and enter the password (0004).
3. Press Enter, the cursor should be over “Step Test”.
4. Press Enter to access the menu.
5. Press Enter, the cursor should be next to “Select HVAC ID”.
6. Press Up or Down until the unit to be tested is selected, then press Enter.
7. Press Down, then press Enter. The cursor should be next to STOP.
8. Use the Up and Down buttons to select the desired test and press Enter to confirm.
9. Repeat Step 8 for all 5 tests. Verify that all components are operating properly. The 5 tests are
supply fan, heater, condenser fan, compressor, and damper.
10. After testing is complete, switch the test to STOP and press Enter.
11. When the step test is complete, return to the main menu by holding Esc.
