Troubleshooting
Manual test is terminated by advancing completely through the test sequence.
The controller will time out if the unit remains in a single step for one hour.
Table 59 on page 91 and Table on page 92 describe the controller output states
for supported unit types.
Test procedure
The procedure for testing is:
1 Press and hold the Test button for at least two seconds, then release the
button to start the test mode. When manual output test mode begins, the
controller turns off all outputs and calibrates modulating end devices
closed.
2 Press the Test button (no more than once per second) to advance through
the test sequence.
Alternatively, the manual output test can be controlled over the
communications network by using the Rover service tool. When conducting the
manual output test via communications network, the sequence must start with
Step 1 (Off), as shown in the following table. However, subsequent steps may
be conducted in any order.
