(6.35 mm) hex nut bit Portable Operator s Terminal with Controller Interface Software Rev. 2.0 or later (required for controller replacement only) Additional tools needed if not using self-tapping option: 1/4 in. (6.35 mm) hex nut driver 1/8 in. (3 mm) bit Prerequisites (Optional) Room temperature sensor installed Air velocity sensors installed in ducts A source of 24 Vac Class 2 power available Supply power to the unit is OFF An air supply line is available at the controller Expected Installation Time New controller installation Replacement (old controller has removable terminal blocks) 10 minutes 6 minutes Replacement (old controller does 16 minutes not have removable terminal blocks) NOTE: You may require additional time for database work at the field panel. New NOTE: These steps only refer to new installations. For replacement instructions, refer to pages 3-4. For Autozero Module installation, refer to instruction The following tasks can be performed by the electrician: 1. Loosen, but do not remove, the cover screws and remove the enclosure cover. Using the rear panel of the enclosure as a template (Figures 1 and 2), mark the location for the four screw holes where you will install the enclosure. 2. Do one of the following: If using the self-tapping screws: Using the drill and the hex nut bit, start the screws. (Screws do not require starter holes.) If not using the self-tapping screws: Drill four 1/8 in. (3 mm) pilot holes for the screws. Using the hex nut driver, start the screws. Item Number: , Rev. FA Page 1 of 7

2 Figure 1. Room Pressurization Controller Pneumatic Output without Autozero Modules. 3. Mount the enclosure on the screws and tighten them down with either the drill or hex nut driver. 4. Remove the appropriate knockouts. 5. Place the ESD wrist strap on your wrist and attach it to a good earth ground. 6. Connect the Local Area Network (LAN) trunk (Figure 4). Run the wiring through knockout. Page 2 of 7 Do not connect an earth ground to the Shield (S) terminal. 7. Connect the point wiring for the appropriate application. See Figure 7. See Table 1 for application descriptions. Run the wiring through knockout. The Controller s Digital Outputs (DOs) control 24 Vac loads only. The maximum rating is 12 VA for each DO. For higher VA requirements, 110 or 220 Vac requirements, separate transformers used to power the load, or DC power requirements, use an interposing 220 V 4-relay module (TEC Relay Module P/N ). NOTE: Each DO provides a Normally Open (NO) and a Common (C) terminal. Terminate both connections of a 24 Vac load directly to the controller board. NOTE: The 24 Vac H terminal is switched through a TRIAC to the NO terminations when the associated DO is energized. 8. If using a pressure mode switch, then follow the Room Pressurization Controller (RPC) Pressue Mode Switch nstallation Instructions ( ) included with the switch. 9. After the pressure mode switch is installed, wire the switch to DO8 and AI3 as described in the instructions. 10. Plug the Room Temperature Sensor cable into the RTS port on the controller board. See Figure 1. Run the cable through knockout. 11. Connect the power trunk as shown in Figure 5. DO NOT apply power to the controller. Run the wiring through knockout. 12. Replace the enclosure cover and tighten the cover screws.

3 The following task can be performed by the fitter: 13. Connect the tubing from the air velocity sensor pickups to the HI and LO ports outside of the enclosure. The supply pickup goes to the supply AVS ports, and the exhaust pickup goes to the exhaust AVS ports on the side of the enclosure. Make sure that the HI and the LO pressure sides of the sensors are connected to the HI and LO sensor ports on the controller (Figure 1) or Autozero Modules (Figure 2). Refer to Table 2 for air velocity sensor connections. The installation is complete. Replacement Instructions Replacement of a TEC requires you to record, re-enter, or update the initial point values of the controller you are replacing. These are the points marked with an asterisk (*) on the Controller Interface Software (CIS) display. NOTE: CIS Rev. 2.0 or later is required for controller replacement. The following tasks can be performed by the system specialist: 1. Place the ESD wrist strap on your wrist and attach it to a good earth ground. 2. Before disconnecting the old controller, do one of the following: NOTE: If the new controller has a newer firmware revision than the old controller, then skip to the third bullet. If the old controller communicates with the field panel, then update the controller initial values at the field panel. If the old controller does not communicate with the field panel, but communicates with the CIS, or if the controller is stand-alone, then record the initial values (those marked with an asterisk (*) on the CIS display). Record the values. If the old controller is not communicating at all, or if the controller you are installing has a newer firmware revision than the old controller, then while at the field panel, follow these steps: a. Obtain a field panel Point Definition Report for the LCTLR point. Record the values. b. View the initial value block. (This information is valid only since the last update was made). Record the values. c. Delete the LCTLR point from the field panel. 3. Replace the old controller as follows: The following tasks can be performed by the electrician: a. Remove power from the controller. b. If the old controller has the RTS plug between the LAN trunk and point terminations, then disconnect the wires from the power trunk terminal block. If the old controller has the RTS plug on the opposite end of the board from the power trunk terminal block, then remove the power trunk terminal block. c. Remove, in the following order, the controller s: LAN trunk terminal block DO8, AI3, and DI2 only room temperature sensor d. Loosen, but do not remove, the mounting screws. e. Lift and remove the old enclosure. f. Mount the new enclosure on the mounting screws and tighten them down with either the drill or hex nut driver. g. Remove the appropriate knockouts. h. If the old controller has the RTS plug between the LAN trunk and point terminations, then remove all terminal blocks (except the power trunk) from the new controller. If the old controller has the RTS plug on the opposite end of the board from the power trunk terminal block, then remove all terminal blocks. Page 3 of 7

4 i. Plug, in the following order, the controller s: pre-wired LAN trunk DO8, AI3, and DI2 j. If the old controller has the RTS plug between the LAN trunk and point terminations, then rewire power to the power trunk terminal block. If the old controller has the RTS plug on the opposite end of the board from the power trunk terminal block, then plug the power trunk terminal block from the old controller into the new controller. k. Connect the room temperature sensor. Run the wiring through knockout. l. Power up the controller. The following tasks can be performed by the fitter: m. Label and remove the polyethylene tubing from the old enclosure. n. After the new enclosure is in place, reconnect the polyethylene tubing. The following tasks can be performed by the system specialist: 4. Set the address and application at the new controller. 5. Based on what you did in Step 2, do one of the following: If you updated the initial values from the old controller at the field panel, then when you set the address and application for the new controller, the field panel will automatically send the initial values down to the new controller. Once this takes place, replacement is complete. If you manually recorded the initial values in the table, then enter them into the new controller. If a field panel is present, then update the controller s initial values. Replacement is complete. If there was no communication at the old controller, or the new controller has a newer firmware revision than the old controller, then enter the initial values into the new controller. At the field panel, add the LCTLR point and update the controller s initial values. The replacement is complete. Figure 2. Room Pressurization Controller Pneumatic Output with Autozero Modules.
