Manual 2100-587DPage 38 of 5833. INDOOR BLOWER OPERATIONThe indoor blower motor is a constant CFM variablespeed direct drive motor. The motor is programmedto respond to individual thermostatic inputs thatwill determine the speed/airflow at which the motoroperates. The motor software maintains the ratedairflow across the range of allowable static whether thesystem is ducted or free blow. It will also maintain theTABLE 9Indoor Blower Performance temperature rise across the gas heat exchanger at themid-point of the allowable rise range automatically.There are not adjustments that can be made in thefield to adjust the airflows for any mode of operation.For duct-free applications where lower operating soundis desired, remove pink wire from “COOL” tap andmove to “Unused” tap.FIGURE 17Furnace Control Board and Blower Control Motor will deliver consistent CFM through voltage supply range with no deterioration(197-253V for 230/208V models, 414-506V for 460V models). Continuous CFM is the total air being circulated during continuous (manual) fan mode. Will occur automatically with a call for “Y1” signal from thermostat. Will occur automatically with a call for “Y2” signal from thermostat. Reduced cooling airflow when pink wire is removed from “COOL” tap on furnace control board and placed on“UNUSED” tap. Will occur automatically with a call for “W” signal from thermostat. Constant CFM of variable speed motor should maintain mid-rise temperature differential through range of allowablestatic.Model RatedESPMaxESPContinuousCFMRated1st StageCoolingCFM Rated2nd StageCoolingCFM Reduced2nd StageCoolingCFM Heating CFM  50,000BTU Input75,000BTU Input100,000BTU Input125,000BTU InputWG3S2 0.15 0.50 800 800 1100 1000 1020 1250 1365 1410WG4S2 0.20 0.50 825 1100 1500 1350 1020 1250 1365 1410WG5S2 0.20 0.50 850 1300 1700 1500 1020 1250 1365 1410
