NOTES:

1.Use copper conductors only.

2.Wire is in accordance with National Electrical Code (NEC). For local codes, replace original wires with 90 C wire or its equivalent.

3.Replace wires from IGV, FLTS, MAT, SAT, OAD, RAD, and ELEC HT with 125 C plenum cable conductor as required.

4.Input channel numbers and points for con®guration of the optional analog output temperature control (AOTC) follow:

CHANNEL	SENSOR	DESCRIPTION
1	SAT	Supply-Air Temperature
2	OAT	Outdoor-Air Temperature
3	MAT	Mixed-Air Temperature
6	SPT	Space-Air Temperature
7	RAT	Return-Air Temperature
34	TEMP	Preheat or Optional Carrier Sensor

5.Reference for wire markers, where `X' represents a numeral:

X Ð Item number on wiring harness BX Ð Box wire

CX Ð Cable

KX Ð Accessory kit wire
