7-1 Operator Interface Introduction

The Standard touchscreen interface lets you control your SCW

Series central chilling station. You can do such things as:

• Control compressors and optional pumps

• View current statuses of operation, such as pressures, temperatures, and capacities

• Handle alarm conditions

The sections in this chapter list special instructions for the standard operator interface.

Note: The screens shown in this chapter are sample screens. Actual screen representations may be slightly different in appearance, but are no different in operation.

On all screens in this controller, the F4 button is reserved for the previous screen function. Some screens, such as the chiller status screen, do not have sufficient space to display a prompt that the F4 performs this function. However, the F4 button will always move to the previous screen and will eventually return to the Main Menu.
