Self Diagnostics Check

All switches on outdoor unit PCB DIP Switch bank SW01 are factory set to OFF. To prepare
for the self diagnostics check:
1. Verify that all indoor unit models are Gen 4. (See "DIP Switch Settings for Use With GEN
4 Indoor Units" earlier in this section.)
2. Flip No. 3 on DIP Switch bank SW01 to ON.
3. Push the reset SW01D button.

1. Power all indoor units.
2. Power all heat recovery units in conjunction with powering indoor units (heat recovery
systems only).
3. Verify the outdoor units to indoor units / heat recovery units communications cable is
installed and terminated correctly.
4. Verify the communications cable between outdoor unit frames is installed and terminated
correctly. Inspect terminals (SODU [B] and SODU [A]) at each outdoor unit.
5. Verify that DIP Switches 6 and / or 7 on the slave outdoor unit(s) were properly adjusted
for the job site configuration. See the "Outdoor Unit DIP Switch Settings" page in the
"PCB Settings" section.
6. Power all outdoor units. Order does not matter on multi-frame installation.
7. As the power is provided to the main printed circuit board (PCB) on the Master outdoor
unit, observe the SSD.
• Wait. The perimeter segments will flash in sequence for forty-five (45) seconds.
• Verify the microprocessor's outdoor unit configuration agrees
with the submittal information approved the design engineer
(see Tables below).
• Confirm that this step has been completed. The date is provided
in sequence, and segment of the sequence will remain lit for two
(2) seconds.
