G.4 PROGRAMMING PROCEDURE
ACS functions which can be viewed or changed are listed in Table G-1 along with their
corresponding command numbers. Functions which can only be viewed (such as actual sensor
readings) are marked “Read Only”. Viewing or changing function values is accomplished as
follows:
1. Select the number of the desired command from Table J-1.
2. To view a parameter, type ?, followed by the command number and then press return
(). For example, to view command no. 00 (HEADER TEMPERATURE), enter:
?00
The header temperature reading will be displayed. All temperature readings are in °F.
3. To program (set) a ACS parameter, type @, followed by the command number, an equal
sign, the parameter value and a trailing zero. For example, to set command 05
(SYSTEM OUTSIDE AIR START TEMPERATURE) to 65°F, enter:
@05=650
Use the above steps to view and/or program the desired ACS functions listed in Table G-1.
