SECTION 4
WIRING SCHEMATICS
4.1 INTRODUCTION
This Section contains wiring schematics for the AirV units.
Figure 4--1 is the schematic for the standard upper unit assembly and it is applicable to all standard units.
Figure 4--2 is the schematic for the Low Profile upper unit assembly.
Figure 4--3 is the schematic for a free blow ceiling unit without heat while Figure 4--4 is a free blow unit with heat.
Figure 4--5 is for a ducted unit with microprocessor control.
Figure 4--6 is for an Upper Unit Heat Pumpwithfree blowapplication andFigure 4--7 is thematching freeblowceiling
unit.
Figure 4--8 is for the Upper Unit Heat Pump ducted application and Figure 4--9 is the matching ducted ceiling unit.
Notethat theductedunitshave115VACpowerfor thecomponentsand12VDCpower forthemicroprocessorcontrol
system.
Figure 4--10isfor theductedorfreeblowapplicationthatusesawall--mountedthermostat,withorwithout thefurnace
option.
Whereapplicable, diagrams thatdesignate115Volt, 60H,1Phase,arealsoavailableusing220V olts, 50H, 1Phase.
Most noteably Figure 4--1 and Figure 4--5.
