Performing a manual output test

The manual output test sequentially controls all outputs to verify their
wiring and operation. Normal operation of the controller is suspended
while the manual output test is being performed.
You can use the manual output test to clear the controller of diagnostics.
If any diagnostics are present when a manual test is initiated, the Status
LED blinks twice. During the second step of the test, the controller
attempts to clear the diagnostics. If the controller cannot clear a diagnos-
tic, the controller exits the manual output test.
You can also use the manual output test for air and water balancing. Step
four of the test provides cooling capacity. Step five provides heating capac-
ity. Step four also opens the outdoor air damper to the minimum occupied
position and controls the duct static-pressure to the duct static-pressure
setpoint.
You can perform the manual output test in three ways:
• Press the Test button to proceed through the test sequence
• Use the Rover service tool
Use the operator display
•
To perform a manual output test using the Test button:
1. Press and hold the Test button for 3 to 4 seconds, then release the
button to start the test mode. The green Status LED light turns Off
when the Test button is pressed, and then it blinks (as described in
Table 59 on page 87) when the button is released to indicate the con-
troller is in manual test mode.
2. Press the Test button (no more than once per second) to advance
through the test sequence. Table 56 on page 85 shows the resulting
activities of the outputs.
3. Finish the test by advancing through the complete test sequence. The
test will end automatically if the unit remains in a single step for ten
hours.
