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 displayrelated 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.
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
DO NOT connect a phone line to any of
the phone jacks on the control board.
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
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”.
PC to Unit Connection
There are three connectors in which to plug the serial
communications cable on the SYNC unit (FIG. 1-a). Each one
is specific 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.
PC2
The PC2 connection is used to retrieve, view, modify, and
restore parameters for controller 2. 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 1-3 Password Window
There are some fields along the bottom of the window (FIG.
1-1): The left field shows the location of the program. The next
field 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 field will show
“Connected”. The right field shows the filename of the
parameter file in the program’s memory (see parameters in
Section 6).

Figure 2-1 SMART TOUCH Status Screen
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 fire. 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 Boiler (secondary) pump,
System (primary) Pump, HW Pump, Blower, Gas Valve,
Run-time Contacts, and Alarm Contacts.

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 boiler, then the
percent of max. power is displayed. Finally, should select
temperatures or the flame 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 Boiler Configuration. 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 boiler 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.
PC Program Instructions
While in the SMART TOUCH Status Screen, you can generate a
log file 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 define a log file 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 filename at the top of the window, and will see
the size increase as data is logged to the file. 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 file 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.
