Check flame and combustion (continued)

4.Navigate to the Service Mode Screen from the Status Screen by pressing the MAIN button and then the SERVICE MODE button.

5.On the Service Screen place Heat Exchanger 1 into operation by selecting Heat Exchanger 1 with the SELECT button and turning the heat exchanger on by pressing the ON/OFF button (OFF indicates that the heat exchanger is off and ON indicates that the heat exchanger should be firing).

6.Insert the probe from a combustion analyzer into the hole left by the removal of the flue temperature sensor.

Note: Heat Exchanger 1 is the top heat exchanger; please ensure the probe is in the top flue sensor location.

7.Once the heat exchanger has modulated up to full fire measure the combustion. The values should be in the range listed in Table 9A below. CO levels should

be less than 200 ppm

for a properly

installed unit.

If the combustion is not within range reference the

Troubleshooting Section in the SYNC Service Manual for

possible causes and corrective actions.

8.Once the Heat Exchanger 1 analysis is complete, test the safety shutoff device by turning the manual shutoff valve to the OFF position and ensuring that Heat Exchanger 1 shuts down and registers an alarm. Open the manual shutoff valve, reset the control, and return to Service Mode.

9.Repeat the same procedure for Heat Exchanger 2 by selecting Heat Exchanger 2 while on the Service Mode Screen. Be certain to insert the probe from the combustion analyzer into the Heat Exchanger 2 flue temperature sensor location.

10.Turn the main power off to the boiler and replace the flue temperature sensor into the flue pipe connection.

11.Place the boiler back into normal operation.

￿WARNING You must replace the flue gas temperature sensor to prevent flue gas spillage into

the room. Failure to comply could result in severe personal injury, death, or substantial property damage.

Installation & Operation Manual

Set space heating operation

Verify space heat circulator mode

The Space Heating Mode controls the system pump (if connected), and both boiler pumps. When the SMART TOUCH control receives a space heating call for heat, it turns on the system pump. If the boiler is not heating an indirect HW (Hot Water) tank, it also turns on the boiler pump. After the space heating call for heat ends, the system pump continues to run for a short period of time. If the boiler pump was running, it continues to run for a short period of time as well. These pump delays are factory set to 30 seconds. If different delays are desired, the appropriate parameters in the control must be changed. See the SYNC Service Manual for a detailed explanation of this procedure.

Set space heating set point temperature

During normal operation, space heating set point temperatures can be adjusted from the Set Points Menu. Press the following buttons to navigate to the Set Points Menu from the Status Screen:

>> >>

1.To change a set point, press the SELECT button next to the user set point parameter.

2.The first time the user set point parameter is accessed, you will be required to enter the user password. The user password is 0704.

3.Using the keypad, enter the password and then press the OK button. If the password is not entered correctly, the screen will revert to the Parameter List Screen and you will not be able to adjust the set point. If a digit has been entered incorrectly, press the left arrow key on the keypad to back the digit up. If the password has been entered correctly, the Parameter Change Screen will appear. The Parameter Change Screen will display the set point being changed, the previous setting of the set point, and adjustment buttons.

4.To adjust the set point, press the + or - buttons to change the value being displayed.

5.Once the set point has been adjusted to the desired setting press the APPLY button to change the set point and return to the Parameter List Screen.
