Before You Begin Verifying Power to the Controller Before You Begin Generic Controller I/O Layout. See Wiring Diagram for application specific details. Communication and DO Indicators The TEC Constant Volume Controller has LEDs to indicate communication (yellow) and the DO (digital output) status BST (green). Verifying Power to the Controller Verify that the controller is powered up. Check that the BST LED on the controller is flashing.
Before You Begin Enabling Actuators MTR 2 TIMING MTR 3 TIMING Your application may not have or use all three points. 1. Use the Table Damper Actuator Run Time and/or the Table Valve Actuator Run Time to set run time(s) for the actuator(s) used by your application. 2. For damper rotation angles other than 90°, set points to the appropriate value. The names of these points vary. (PTS4 rotation angle is 90°.) If Motor 3 is a valve actuator, use the Valve Actuator Run Time to set MTR 3 TIMING.
Before You Begin Enabling Actuators NOTE: The assumptions for this table are: - Dampers are Normally Closed (NC) - Heating valves are Normally Open (NO) MTR SETUP Value for Most Common Configurations.
Before You Begin Setting the Application Setting the Application Set APPLICATION to the appropriate Constant Volume Controller application. Application Description Application Number Constant Volume Cooling Only 2030 Constant Volume with Electric Reheat 2032 Constant Volume with Hot Water Reheat 2033 Slave Mode 2092 After you set the application, the controller goes through a shut-down/load sequence as it switches from slave mode to the application selected.
Before You Begin Enabling Autozero Module Enabling Autozero Module If an Autozero Module is used, enable it by setting CAL MODULE to YES. NOTE: For a controller without an Autozero Module, the damper is commanded closed to get a zero airflow reading during calibration. For a controller with an Autozero Module, the damper is closed only for the first calibration after controller initialization or power up. Selecting Automatic Calibration Option 1.
Before You Begin Setting Room Temperature Setpoints Setting Room Temperature Setpoints Day (or OCC) cooling setpoint: DAY CLG STPT or OCC CLG STPT Day (or OCC) heating setpoint: DAY HTG STPT or OCC HTG STPT Night (or UOC) cooling setpoint: NGT CLG STPT or UOC CLG STPT Night (or UOC) heating setpoint: NGT HTG STPT or UOC HTG STPT 1. If the room temperature sensor has a setpoint dial that will be used, set STPT DIAL to YES. Otherwise, leave STPT DIAL to NO.
Before You Begin Setting Override Time Setting Override Time If using night/unoccupied override, set OVRD TIME to the number of whole hours that an override should last. If OVRD TIME equals 0 (default), this feature is disabled. Enabling Wall Switch If a wall switch is used for day/night (occupied/unoccupied) control, enable it by setting WALL SWITCH to YES. Otherwise, leave WALL SWITCH at its default value of NO.
Before You Begin Setting Airflow Setpoints Box Manufacturer Flow Coefficients Manufacturer Carnes Sensor Type Value Spider without orifice Spider with orifice 0.73 0.39 2-pipe Flow cross 0.66 0.59 Carrier 0.59 E.H. Price/Siemens Industry Terminal Boxes 0.78 Environmental Technologies 0.79 Krueger 0.68 Metal Aire 0.72 Nailor Industries 0.69 Titus 0.60 Trane 0.66 Setting Airflow Setpoints Applications 2030, 2032, and 2033 UNOCC FLOW must be set equal to or less than OCC FLOW. 1.
Before You Begin Secure Mode Secure Mode After updating the controller at the field panel, Secure Mode can be enabled/disabled through the Insight workstation. Once enabled, modification of any configuration or override points is prevented. See application documentation for more information. 12 Siemens Industry, Inc.
