NOTES:
1 - The controller's wiring harness is designed specifically for EcoBlue,
Axiom-Fan, X- Vane units with the Unit Control Board (UCB). If your
unit has the older CTB (Central Terminal Board) or Centrifugal
Supply Blower then you must purchase a different harness.
(MicroMetl P/N 9962-0407 & 9962-0407SAOAEXT, if a NV customer,
then purchase P/N 1002-0407).
2 - If you have a 48/50JC 04-07 unit with System VU, these
controls will not work properly. Please let your distributor
know that you will need an ECD-SRT12CB-D0DB-4 economizer.
