ECC Program Override

  1. During display of BCM data on FDC panel, the CCP panel will display a 2-digit number that represents various levels of heating and cooling effort. As "F.8.0" first appears on FDC, CCP will begin displaying program number currently being used by climate control system. As operating conditions change, number will automatically change in response.
  2. Automatic calculation of program number can be by-passed by a manual override feature by depressing "WARMER" and "COOLER" buttons. This manual override system allows service technician to control program number between zero (maximum A/C) and "100" (maximum heat), and simultaneously observe reaction of any BCM data parameter.
