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 Pump with free blow application and Figure 4--7 is the matching free blow ceiling unit.

Figure 4--8 is for the Upper Unit Heat Pump ducted application and Figure 4--9 is the matching ducted ceiling unit.

Note that the ducted units have 115 VAC power for the components and 12 VDC power for the microprocessor control system.

Figure 4--10 is for the ducted or free blow application that uses a wall--mounted thermostat, with or without the furnace option.

Where applicable, diagrams that designate 115 Volt, 60 H, 1 Phase, are also available using 220 Volts, 50 H, 1 Phase. Most noteably Figure 4--1 and Figure 4--5.
