Parameter information screens

By accessing the Parameter Information Screens on the SMART TOUCH program, the installer can view all of the SMART TOUCH parameters. The installer can also change certain specific parameters to fine tune the operation of the boiler to the installation.

NOTE The PC cable must be connected to either the PC1 or PC2 connection. When connected, the status screen on the SYNC will show a communication error. This will clear automatically when the cable is removed.

To access the parameter list, click on the Parameters button along the top of the Main Screen window (FIG. 6-1). Next click on Retrieve Parameters from Controller in the pull down menu (see FIG. 6-1). This will upload the current parameters in the SMART TOUCH to the PC.

Adjustable parameters are located in:

Set 1: System Setup

Set 2: Functional Data

Set 4: Menu Values

While many parameters are viewable in each set, only select parameters are adjustable. To make an adjustment to a parameter, select the parameter to be changed from the appropriate set. Click on the box next to the parameter and type in the value for the parameter.

Once an adjustment has been made to a parameter, it must be programmed into the SMART TOUCH. On the Parameter pull down menu, click on the Program Parameters into Control button. This will bring up another pull down menu. If a parameter was changed in just one set, select the set from the menu and click on it. If changes were made in multiple sets, select the Store Parameter Set 0-4from the menu and click on it. This will program the new parameters into the SMART TOUCH. If the parameters are based on a parameter set from a different model, they may not be compatible with this model. In that case, the program will display a message to let you know. You may compare parameter 1AR in the SMART TOUCH control, and in the new parameter file, to determine if they are compatible.

While the programming is taking place, the SMART TOUCH will go into a lockout mode. It will require that the Reset button on the display be pressed after the programming has been completed before the unit will be allowed to operate.
