The effect of static pressure is included in air volumes shown.
The following control congurations 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 ring rate based on rst- and second-stage cycle times
- W1 demand at 70% input, W2 demand at 100% input. No delay between stages
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 450 cfm.
