NOTES:
1. If any of the odginel wires furniabed are reol_ced, thay must be
replaced with type 90 degree C wire or its equivalent.
2. Seepricopagesforthermostatandsubbases.
3. Use 75 degree C copper conductors for field installation.
4. For high speed IFM, dis_3nnect RED wire from IGC terminal BM
and connect BLK w_re from IFM, For medium speed, disconnect
RED wire from IGC terminal BM and connect BLU wire from IFM.
