Page 17 Tstat Series Advanced Menu Item Details The Tstat6 series thermostats have several advanced menu items which can be adjusted in the ﬁ eld to suit the application and tune the operation of the thermostat. Generally speaking, all the parameters are set up at the factory on an order-by-order basis and will give satisfactory results out of the box.
Page 18 Tstat Series Code Description (Range, Default) Modbus Device Address (1-254, 254) This is the modbus address of the tstat. It is the address to which the stat will respond when receiving serial communication. Calibration of the Selected Temperature Sensor (0-1000, 500) To calibrate the temperature shown on the tstat display you will need a handheld mercury thermometer or digital thermometer.
Page 19 Tstat Series Code Description (Range, Default) Proportional Term (10-255, 20) The proportional term is the ‘P’ term of the familiar PID control strategy and determines how fast a valve will react to a deviation from setpoint at a particular instant in time. The default value of 2.0° (C or F) is ﬁ ne for most applications, where a 2.0° deviation is required to make the valve respond 100%.
Page 20 Tstat Series Code Description (Range, Default) Heating & Cooling Deadbands (1-200, 10) If there is one setpoint, the heating setpoint follows the cooling setpoint and is calculated by: Heating Setpoint = Setpoint - Heating Deadband. Cooling Setpoint = Setpoint + Cooling Deadband If there are two setpoints, heating and cooling are separately adjusted.
Page 21 Tstat Series Code Description (Range, Default) Output settings (0-4, 0) Sets the full-scale voltage of the analog outputs. Ou1 sets analog out 1 (Cooling). Ou2 sets analog out 2 (Heating). This setting is used to match the analog outputs to various types of actuators, transducers or other controllers.

Page 27 Tstat Series Tstat6: Getting Started This example will show you how to properly set up a new Tstat6 and attach a couple external devices to the unit. In this example we will use a DTS-FL-4-6-7 temperature sensor and a PSN 30-300A air differential pressure switch, to be read by the Tstat6.
Page 28 Tstat Series Start the T3000 program. If you do not want to clear the building view to create an easier working space than skip to step 6. Otherwise go to the menu and select “Database >> All Nodes” and click the “Del All” button to clear the ‘Default Buildings’...
Page 29 Tstat Series Now click the “Discover” button, circled green in the picture above. T3000 will actively search your computer’s ports and ﬁ nd the Tstat6 that is connected. Once it has ﬁ nished it will show a pop up window, shown below, with the Tstat6’s information shown.
Page 30 Tstat Series We now must pick the appropriate ranges, according to our devices, so that the values being displayed will be meaning- ful for that partiuclar input. To do this, click on the box under the range column, representing which input you want to adjust.
