Indoor Blower Speeds

1.When the thermostat is set to AN ON," the indoor blower will run continuously at approximately 38% of the second−stage cooling speed when there is no cool- ing or heating demand.

2.When the CBWMV is in the heating mode, the indoor blower will run on the heating speed designated by the position of the HEAT pin.

3.When there is a cooling demand, the indoor blower will run on the cooling speed designated by the position of the COOL pin.
