Deduct these resistance values from the available external static pressure shown in Table 10, 11, 12, and 132. The pressure through the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return airduct system is less then 0.25 IWG, the unit will deliver less CFM during full economizer operation.RGWRGCYYWCPROGRAMMABLETHERMOSTAT ONLY**** = Minimum wire size of 18 AWGwire should be used for allfield installed 24 volt wire.THERMOSTAT UNIT TERMINAL STRIPNOTE:HEAT ANTICIPATORSHOULD BE SET AT 0.35AMPS FOR ALL MODELS.24 VOLTTRANSFORMERGROUNDLUGREFERTOELECTRICALDATATABLESTOSIZETHEDISCONNECTFIELD-SUPPLIEDDISCONNECTCONTACTORFIELD-SUPPLIEDDISCONNECTCONTACTORGROUNDLUGREFERTOELECTRICALDATATABLESTOSIZETHEDISCONNECTSINGLEPHASEPOWERSUPPLYTHREEPHASEPOWERSUPPLY |
