Temps Screen:

The Temps Screen displays the various temperatures as measured by sensors connected to each control module. Items that can be viewed on the Temps Screen are as follows:

•Heat Exchanger 1/2 Inlet - This is the water temperature as measured by the sensor located in the inlet of each heat exchanger.

•Heat Exchanger 1/2 Outlet - This is the water temperature as measured by the sensor located in the outlet of each heat exchanger.

•Heat Exchanger 1/2 Flue - This is the temperature as measured by the sensor located in the flue connection on each heat exchanger.

•Set Point - Two temperatures are shown in this display. the top temperature is the Cascade Maximum Outlet Temperature. The lower temperature is the tank set point for a Hot Water Generation call.

•System Sensor - This is the water temperature as measured by the sensor located in the system supply piping. The system sensor must be installed for the proper operation of the boiler.

•Outdoor Sensor - This is the temperature of the outside air as measured by the sensor located outside. The use of the outdoor sensor is optional. If the sensor is connected the control will calculate the set point based on the programmed outdoor parameters. See page 22 for information regarding adjusting the outdoor parameters. If the sensor is not present, none will be shown in the display.

Time - The time is displayed in the upper right-hand corner of the display. It is displayed in 24 hour format. Reference the night setback parameters on page 24 for information regarding adjusting the date and time.

Status button - Pressing this button displays the Status Screen. this screen shows the current status of the SYNC boiler. Reference page 13 for more information regarding this screen.
