2) Cap all unused wires.
3) When BK is used, do not connect Y2 at the air handler.
4) When BK is used, cut the jumper between R and BK on the
control board. See indoor wiring schematic for details.
5) In AC systems, for multiple stages of electric heat, jumper
W1 and W2 together if comfort control has only one stage of heat.

Mitigation Board Guidelines
•
The approved ID/OD combination will provide sufficient safe ventilation in case of a leak.
•
Refer to Indoor Unit Installer's Guide for correct specifications on indoor unit install.
•
All systems require mitigation boards so an altitude adjustment factor may be required.
•
Mitigation Control Board needs to be included in an A2L System.
