The System Touch has built-in temperature and humidity sensors. You can use their values to control equipment.
You can also wire an external thermistor to the System Touch and use its value instead of the built-in temperature
sensor's value.
You can install and run the System Touch with only its built-in system screens, or you can create a custom
touchscreen file in ViewBuilder. This requires that you create custom screens in ViewBuilder, and then save the
touchscreen (.touch) file. See "Working with System Touch screens" in ViewBuilder Help.
NOTE To use custom screens, the System Touch must have v2.00-015 or later firmware.

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.

Step 4: Optional -Install custom screen file
PREREQUISITES
• The System Touch must have v2.00-015 or later firmware to display custom screens.
You need a USB flash drive that is formatted as FAT, FAT16, or FAT32. To verify, insert the flash drive into
your computer, then right-click the flash drive in Windows Explorer and select Properties. File system should
show FATxx. If File system shows NTFS or anything else, you must reformat the drive. Right-click the flash
drive, then select Format. In the File system field, select FAT (Default), then click Start.
Before you install your custom screen file, make sure that the creator of the file included navigation from the
custom screens to the system screens.
Follow the steps below in order. If you select Viewfile (step 3) on the display before you insert the USB drive
(step 2), the touchscreen will become inoperable.
To install the custom screen file:
1 Create a folder on the flash drive called Touch, then put the xxxxxx.stv file in the folder.
2 From the System Touch's Home screen, touch Setup > Viewfile.
3Plug the flash drive into the System Touch's USB port.
4 Touch OK. The following series of messages appear:
Verifying Firmware Image.
Loading View file.
5When the Home screen displays, remove the flash drive.
NOTE To remove the .stv file from the System Touch so that it returns to its original state with only built-in
screens, follow the procedure above except remove all files from the Touch folder mentioned in step 1.
Step 5: Set up scheduling functionality
You can define BACnet schedules for any controller whose control program(s) support time schedules.
To allow a user to create schedules on the Equipment Touch:
1 In the i-Vu® or Field Assistant tree, right-click the controller, and then select Driver Properties.
2On the Settings tab, scroll down to TouchScreen Control and verify that TouchScreen Schedule Edit Enable is
checked.
_CAUTION If scheduling for this system will be done in the i-Vu® interface, you should disable scheduling in
the System Touch so that they do not overwrite each other's schedules. To disable scheduling, uncheck the
TouchScreen Schedule Edit Enable field on the controller's Driver page.
See "To create a schedule for a group of equipment" in the System Touch User Guide.
