*All units are 2-stage heat.

NOTE: Minimum allowable temperature of mixed-air entering the heat exchanger during ®rst-stage heating is 45 F. There is no minimum mixed-air temperature limitation during second-stage heating. For entering-air temperatures below 45 F both stages of heat must be energized together to minimize condensation issues and to ensure proper unit operation.
