WhatistheSystemTouch?
To set up a System Touch:
1Connect the System Touch to an MS/TP network (page 9).
2Discover BACnet devices on the same network or on a different BACnet ARCnet or BACnet MS/TP network
(page 12).
3Create the system database (page 12).
4Install custom screen file (optional) (page 12).
After you set up your system, you can:
• Schedule when equipment should run
• View alarms
• View Equipment Touch screens for individual controllers on the network. The information on the controller
screens depends on whether the controller is a Carrier controller or a third-party controller, and if it is an
Carrier controller, whether it has an Equipment Touch file.
NOTE To see a controller's Equipment Touch screens on the System Touch, the Equipment Touch file must
be downloaded to the controller before you create the System Touch database.
