Figure 2-1SMART 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.
