Notes:
1. At the beginning of step 2, the controller attempts to clear all diagnostics.
2. For all 1-heat/1-cool applications including 2-pipe changeover, the cooling and heat test stage energize. This occurs even
though during normal 2-pipe changeover operation binary output controls the unit valve for both cooling and heating.
3. After the fresh air damper step, the test sequence performs the exit step.This initiates a reset and attempts to return the
controller to normal operation.
4.
The 2-position damper energizes during this step if the controller is configured for a 2-position damper.
5. ZN010 and ZN510 has a binary output default as “none” on J1- X from the factory. If the unit has a 2-speed fan, step 3 will
energize the low fan speed. If the unit has a single speed fan, step 3 will continue to energize the high fan speed. This
binary output can be reconfigured as an exhaust fan, with the use of Rover software

Note 1. Upon entering manual output test mode, the controller turns off all fan and electric heat outputs and drives.
Note 2. At the beginning of step 2, the controller attempts to clear all diagnostics.
Note 3. The low fan speed output energizes at step 3. If the unit is configured for a 1 speed fan, the fan remains on high
speed at step 3.
Note 4. If the unit is configured for a 1 or 2 speed fan, and BOP2 is configured for an exhaust fan, the exhaust fan output
energizes on step 7. The exhaust fan output is shared with medium speed.
Note 5. After step 10, the test sequence performs an exit. This initiates a reset and attempts to return the controller to
normal operation.
The green LED is turned off when the
Test button is pressed. To begin the
manual output test mode, press and hold
the Test button (turning off the green
LED) for at least two seconds. The green
LED will begin to blink, indicating the
controller is in test mode.
