Program installation

There are two programs available for programming and monitoring the appliances. SITECS937Lab is used to monitor the operation of the appliance 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 speciﬁ c 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 ComPorts 1 - If the ComPort assigned by your computer is a value 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”.

4. Click on the “Port Settings” tab, then on the “Advanced”button. Select an unused ComPort number (preferably COM1) in the range of COM1 to COM16. Click on OK. Click OK on the previous window and then close all of the other windows.

5. Restart your PC to make sure the new ComPort number is active. When you attach the USB cable to the PC, the PC should recognize the cable. The next time you start up the SMART TOUCH PC and SITECS937Lab programs, click on the “Settings” tab at the top of the screen, then click on“ComPort”. Select the ComPort number assigned to the USB cable above.

The programs display temperatures in °F. If you wish to display temperatures in °C, click on the Settings tab along the top of the Main Screen window, and move the cursor over Temperature > in the pull-down menu. A new menu will appear, click on Celsius.

CAUTION

PC to Unit Connection

There are three connectors in which to plug the serial communications cable on the unit (FIG. 1-a). Each one is speciﬁ c to a particular function.

PC Connection

The PC connection is used to monitor the unit performance, data logging, programming the service provider’s name and phone number, and setting selected display parameters. Use the SITECS937Lab program for these functions.

PC1

The PC1 connection is used to retrieve, view, modify, and restore parameters for controller 1. Use the SMART TOUCH PC program for these functions.

Starting the program

To start one of the programs, double-click on the icon (if you put it on your desktop), or click on Start, then Programs, and select the program you wish to start. See FIG 1-1 and FIG 1-2 above.

There are two access levels for this program. The user access level allows only certain settings to be changed. The installer access level allows more settings to be changed. The program defaults to the user level when started. You will notice that a lock symbol appears in the lower right-hand corner of the window. To move to the installer level, a password must be entered. This password is located on a label on the CD-ROM case. You may enter the password by clicking on the “key” button in the upper left-hand corner of the window. A window opens in which you can type in the password (see FIG. 1-3). Note that the password is case sensitive and is in all CAPS. Click on the Ok button, or press the Enter key. You will notice that the lock symbol at the lower right-hand corner of the window has changed into a key symbol.

Figure 1-2

There are some ﬁ elds along the bottom of the window (FIG. 1-1): The left ﬁ eld shows the location of the program. The next ﬁ eld shows the status of the communication between the PC and the SMART TOUCH. This will say “No connection” when the program is started. As soon as the program sends or receives data from the SMART TOUCH, this ﬁ eld will show “Connected”. The right ﬁ eld shows the ﬁ lename of the parameter ﬁ le in the program’s memory (see parameters in Section 6).

PC Program Instructions

To monitor and record the operation of the heater, click on the Status tab along the top of the Main Screen window (FIG. 1-1, page 4). When using the SITECS937Lab program, you will need to choose which controller you wish to monitor. The Status Screen will appear (see FIG. 2-1 above). The screen is divided into several sections.

The Sensors section displays the current temperatures seen by the Inlet, Outlet, System Inlet, System Outlet, Tank, Outdoor, and Flue sensors. It also shows the delta T across the heat exchanger and the voltage being applied to the 0-10Vdc input (FIG. 2-1). The controlling sensor is shown below the items mentioned above. The default controlling sensor is the Outlet sensor. If a System Supply sensor is connected, the control will automatically use it as the controlling sensor.

Below the temperature readings are Derivative Flue and Derivative Outlet. These show how quickly these temperatures are changing. The control will take certain actions based on these values. For instance, if the outlet temperature rises too quickly, the control will force the heater to run at low ﬁ re. Finally, the 0-10Vdc input Voltage and Flame Current are shown.

To the right of the sensor temperature readings are the various setpoints. The SH setpoint is the setpoint the SMART TOUCH uses during a space heating call for heat. Note that this setpoint will depend upon the outdoor temperature if the outdoor air sensor is connected. When the 0-10Vdc input is used, this setpoint will vary with the input voltage if it is used to control the setpoint. The HW setpoint is the setpoint used when a Tank sensor is connected. The HW Mod Setpt is the outlet temperature setpoint used when heating an indirect HW tank. The dSP setpoint is not used. Below these is a check box indicating if Night Setback is active or not.

Below the Sensors section is the Inputs section (FIG. 2-1). This section displays the status of the Enable (SH Thermostat) Input, HW Thermostat, Manual Reset High Limit, Flow Switch/Low Water Cutoff (optional), Gas Pressure Switch, Louver Proving Switch (optional), Air Pressure Switch, Blocked Drain Switch, Auto Reset High Limit Switch, and the status of the SH and DHW demands from ModBus.

Next to the Inputs section is the Outputs section (FIG. 2-1). This section shows the status of the Appliance (secondary) pump, System (primary) Pump, HW Pump, Blower, Gas Valve, Run-time Contacts, and Alarm Contacts.

PC Program Instructions

At the top right of the window is the Fan Speed status information. Included in the Fan Speed status are Min., Max., and Ignition fan speeds. If Ramp Delay is activated, the Ramp Delay limit is shown. The target and actual fan speeds are displayed, and if the actual speed is within acceptable limits. If the SMART TOUCH is programmed to be controlled by a Building Management System (BMS), and programmed to have the BMS control the power from the unit, then the percent of max. power is displayed. Finally, should select temperatures or the ﬂ ame current approach certain limits, the SMART TOUCH will force the fan speed up or down accordingly to prevent exceeding those limits. When this happens, the box next to the corresponding sensor is checked.

Below the Fan Speed status is the Unit Conﬁ guration. This indicates the application to which the SMART TOUCH is programmed to be used and the source of control.

Finally, the General status of the appliance is shown. Included in the General status is the active call for heat (if any), the active limits (if any), the last active limit, the burner status, the last fault, and the date and time as stored in the SMART TOUCH.

While in the SMART TOUCH Status Screen, you can generate a log ﬁ le of the readings as the heater operates. Click on the Options button at the bottom right-hand corner of the screen (FIG. 2-1). Press the LogFile button and deﬁ ne a log ﬁ le name and the directory in which you want it to be located. Click OK. When you want to start logging data, click the Log button. The Log button will turn green to indicate that it is logging. You will also notice the ﬁ lename at the top of the window, and will see the size increase as data is logged to the ﬁ le. To stop logging, click on the Options button, then click on the Log button again. The Log button will turn back to gray to indicate that logging has stopped. If you desire to log data over an extended period of time, you may want to select a longer Log every time so the log ﬁ le doesn’t grow too large.

You can also produce a bitmap of the window. Click on the Options button, then the Bitmap button. A bitmap of the window will be saved into the ENCONFLS directory below the directory in which the SMART TOUCH program resides.
