*All units are 2-stage heat.
NOTE: Minimum allowable temperature of mixed-air entering the heat exchanger during first-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.
