If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver less CFM during full economizer operation. NOTE: HEAT ANTICIPATOR SHOULD BE SET AT 0.35 AMPS FOR ALL MODELS. THERMOSTAT UNIT TERMINAL STRIP : Minimum wire size of 18 AWG wire should be used for all field installed 24 volt wire. ©- ** R G ©- Y W- C 24 VOLT TRANSFORMER PROGRAMMABLE THERMOSTAT ONLY FIGURE 3 - TYPICAL FIELD CONTROL WIRING DIAGRAM CONTACTOR GROUND LUG L l_.
