Adiustable Field Configurations - After logging on, press
ri H to enter subfunction. The subfunction allows oper-
ation of the chiller to be customized to meet the particular needs of the application. The chiller comes from the fac-
tory preconfigured to meet the needs of most applications. Each item should be checked to determine which configu- ration alternative best meets the needs of a particular appli- cation. See Table 13 for factory loaded configuration codes and alternative configurations.
If processor module is replaced, the replacement module is preloaded with factory default configuration codes. Each configuration code must be checked and, if necessary, re- configured to m e e t n e e d s o f t h e a p p l i c a t i o n . S e e Table 13 for
Service Configuration Codes - Press r;lH to enter the
service configuration subfunction. The first 2 items under this subfunction are 2 groups (8 digits each) of configura- tion codes that are downloaded at the factory. If processor module is replaced in the field, the 2 groups of configura- tion codes must be entered through the keypad and display module. The 2 groups of configuration codes (groups 7 and
8)that apply to the unit being serviced can be found on a label diagram inside the control box cover. See Table 12 for keystroke information to enter configuration codes 7 and 8.
SCHEDULE FUNCTION - This function provides a means to automatically switch chiller from an occupied mode to an unoccupied mode, When using schedule function, chilled water pump relay must be used to switch chilled water pump on and off. Connections for chilled water pump relay are:
