1
Note : Upon entering manual output test mode, the controller turns off all fan outputs and drives all
dampers and valves closed (if required).
2
Note : At the beginning of step 2, the controller attempts to clear all diagnostics.
3
Note : If the unit is configured for a 2-speed fan, the fan remains on high speed at step 3.
4
Note : 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.
5
Note : 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.
6
Note : After step 10, the test sequence performs an exit. This initiates a reset and attempts to return
the controller to normal operation.
Minimum timers
The outputs are not subject to minimum times during the test sequence.
However, the test sequence only permits one step per second, which enforces a
minimum output time.
LED operation
The green status LED is off when you press the Test button. To begin the
manual output test mode, press and hold the Test button (which causes the
green LED to go off) for at least two seconds, then release the button. The green
LED blinks, indicating the controller is in manual test mode.
