Notes:
1. “YI” and “YO” connections must be made as shown for freeze
protection and internally mounted condensate overflow circuits to
work properly
2. If third party condenstate overflow switched are installed, they
should be wired between “Y1” of the thermostat and “YI” of the
airflow control board
