BS01 Program Number

BSO1 Program Number

As heating and air conditioning operating conditions change, the program number will automatically change in response. The automatic calculation of program number can be bypassed by a manual override feature using the "WARM" and "COOL" buttons on the secondary display panel. Touching the "WARM" button will force the program number to increase at a controlled rate until a value of "99" is reached. "99" represents the "MAX HEAT" mode of climate control operation. Touching the "COOL" button will force the program number to decrease until a value of "0" is reached, which represents the "MAX A/C" mode. This manual override of the automatic program number calculation will continue until the override is stopped. This allows the technician to control the program number from "0" to "99" and simultaneously observe the reaction of any of the BCM data parameters.
