Table 58 Test sequence for non-face and bypass unit configurations
Note
1
: Upon entering manual output test mode, the controller turns off all fan and electric heat outputs
and drives all dampers and valves closed (if required).
Note
2
: At the beginning of step 2, the controller attempts to clear all diagnostics.
Note
3
: If the unit is configured for a 3-speed fan, the medium fan speed output will energize at step 3.
If the unit is configured for a 2-speed fan, the fan remains on high speed at step 3.
Note
4
: If the unit is configured for a 3-speed fan, the medium fan speed output energizes at step 3. If
the unit is configured for a 2-speed fan, the low fan speed output engergizes at step 3. If the unit is
configured for a 1-speed fan, the fan remains on high speed at step 3.
Note
5
: If the unit is configured for a 1- or 2-speed fan, the exhaust fan output energizes on step 7. The
exhaust fan output is shared with medium fan speed.
Note
6
: After step 10, the test sequence performs an exit. This initiates a reset and attempts to return
the controller to normal operation.
