The effect of static pressure is included in air volumes shown.

The following control configurations are available. See Installation Instructions for details and DIP switch settings.

Heat Modes Available (Heating Blower Performance Table):

Single stage thermostat:

-35%, 70%, 100% input (three-stage) with time delays in-between

Two-stage thermostat:

-Variable Rate Capacity Mode - furnace automatically adjusts firing rate based on first- and second-stage cycle times

-W1 demand at 70% input, W2 demand at 100% input. No delay between stages

icomfort Touch™ Communicating Thermostat:

-Variable Rate Capacity Mode - furnace automatically adjusts firing rate based on first- and second-stage cycle times

-35%, 60%, 80%, 100% (four-stage) with time delays in-between

Cool Mode Available (Cooling Blower Performance table):

First stage COOL (two-stage air conditioning units only) is approximately 70% of the same second stage COOL speed position.

Continuous Fan speeds are approximately 28%, 38%, 70% and 100% (DIP switch selectable) of the same second-stage COOL speed position minimum 300 cfm.

Lennox Harmony III™ Zoning System Applications - Minimum blower speed is 250 cfm.
