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 configuration of the optional
analog output temperature control (AOTC) follow:
