Program installation

There are two programs available for programming and monitoring the SYNC boilers. SITECS937Lab is used to monitor the operation of the boiler and program a few display- related parameters. SMART TOUCH PC is used to program the bulk of the parameters in the controls.

To begin installation of the programs, please insert your SMART SYSTEM CD into the CD drive. If you have Autostart enabled, the SMART SYSTEM software screen will load. If not, navigate to CD drive and double-click on index.html. Once the screen opens, select the program you wish to install. Follow the prompts, and after all the desired programs are installed, restart your computer.

If you wish to have the PC program icons on your desktop, click on START, and then Programs. Right click on SMART TOUCH PC. Place the cursor over Send to >, and then click on Desktop. Repeat this procedure for the SITECS937Lab program.

USB installation

Your PC will communicate with the SMART TOUCH control through the USB cable included with your kit. This cable will require a specific USB driver. This driver may be installed by starting the SMART TOUCH PC program, clicking on the Settings pull-down menu, and clicking on the Comport > item. In the next menu, you will have the option of installing one of two USB drivers. Select the option appropriate for the operating system used by your PC. The necessary driver will install automatically.

Program setup

The PC will assign a ComPort to your new adapter. You will need to know the ComPort number it uses in order to tell the SMART TOUCH PC program which one to communicate with:

1.Click on the following:

-Start

-Control Panel

-System icon (use the Classic View)

-Device Manager button

You will see a list of the hardware on your PC.

2.Double click on “Ports (COM&LPT)”. You will see an entry called “USB Serial Port (COM4)”. The ComPort number may be different on your computer but the device description will be the same. The SMART TOUCH PC program can communicate through Com- ports 1 - If the Comport assigned by your computer is avalue larger than what is available in the SMART TOUCH PC program, you will need to manually reassign the ComPort on your computer.

3. Go back to the “Ports (COM & LPT)” area referenced and take note of any unused ComPort between COM1 to COM16. Double click on the “USB Serial Port”.
