Installation Instructions Document No. 129-477 November 15, 2017 Series 2200 RoomUnits Page 1 of 4 Product Description These room units measure temperature in the occupied space in which they are installed. Models with display allow users to view the measured temperature value. A version with temperature setpoint adjustment is also offered. The effective sensing and setpoint range is 55°F to 95°F (13°C to 35°C). These room units can be mounted on electrical boxes, stud-type mounting brackets, or drywall. Hardware is included for installation on drywall or on a 2” × 4” electrical box.

Expected Installation Time 20 minutes Item Number 129-477, Rev. JA Required Tools • Sizes 1 and 2 Phillips screwdrivers • Small and medium flat-blade screwdrivers • 1/16-inch hex key • Medium-duty electric drill • 3/16-inch (4.8 mm) drill bit • One-inch (25 mm) hole saw • Small level • Tape measure • Marker or pencil Prerequisites • Review these instructions before beginning. • Installed: appropriate field wiring within the maximum wiring run length for the individual equipment controller. The maximum recommended length is 100 feet (30 m). • All wiring must comply with National Electric Code (NEC) and local regulations. Figure 1. Typical Temperature Room Unit.Document No. 129-477 Installation Instructions November 15, 2017 Page 2 of 4Siemens Industry, Inc. Mounting Information Always mount the room unit vertically. Locate the room unit: • according to design specifications and local regulations. • where the air circulates around it freely (not in recessed areas or behind doors). • allowing a minimum of 4 inches (10 cm) free space above and below for proper airflow, the front cover removal tool, and the computer communication cable. • away from drafts caused by doors, windows, outside walls, air registers, pipes, return air plenums, and so on. • away from heat sources such as strong lights, fireplaces, direct sunlight, and so on. • on an inside wall (preferably), about 5 feet (1.5 m) above the finished floor, or per code (ANSI, ADA, or local regulation). Drywall Mounting (No Rough-in), Typical Base Plate Mounting and Wiring 1. Mark the center (cable) hole and the mounting hole locations, using the temperature sensor base plate as a template. See Figure 3. 2. Drill two 3/16-inch (4.8 mm) mounting holes and mount the two plastic wall anchors flush to below the wall surface for stable mounting of the device. 3. Cut a 1-inch (25 mm) center hole with a hole saw. NOTE: It is recommended that you use the optional insulating gasket on the back of the Sensor Base for hollow wall installations. When applying the adhesive-backed gasket to the back of the Sensor Base, orient the gasket so that the cut-out arrow portion of the gasket is in the upper left-hand quadrant of the Sensor Base. The Sensor Base has anUP arrow molded into the surface in the same quadrant location (see Figure 6). Figure 2. Insulating Gasket. 4. Pull about three inches (75 mm) of the cable through the hole in the base plate. 5. Mount the room unit base plate on the wall, noting the UP arrow: NOTE: If required, position the back plate behind the room unit base, aligning the top and bottom mounting holes, prior to mounting to the wall: a. Install the two mounting screws provided, but do not tighten. b. Level the room unit base plate for appearance. c. Tighten the two mounting screws to the room unit base plate. 6. Cut the cable, leaving about three inches (75 mm) on the room unit side of the drywall. Ensure that pin Number 1 connects to the same wire at each end of the cable. NOTE:See Figure 2 for details on optional Gasket application. Figure 3. Drywall Mounting (No Rough-in), Typical.Document No. 129-477 Installation Instructions November 15, 2017 Siemens Industry, Inc.Page 3 of 4 7. Terminate the wires to the termination blocks on the room unit's base plate. (See Figure 6.) 8. Feed the extra cable back through the hole. Sensor Set-up Figure 4. Circuit Board (Located inside Room Unit Cover. 1. If the device has a switch, determine if voltage or current output is needed. • For current, set the switch in the down position (I). • For voltage, set the switch in the up position (V). NOTE: The output setting applies to all outputs (temperature, and setpoint). 2. If selecting voltage, set the jumper: • Use the top and middle pins for 0 to 5V. • Use the bottom and middle pins for 0 to 10V. NOTE: If the jumper is missing or removed, the output voltage will default to 0 to 10V. NOTE:The factory default for displayed temperature units is °F. To change the display to °C, snip the wire jumper (0 Ohm resistor R64) on the back of the PCA. Figure 5. Changing Display to °C. 3. Snap the room unit cover to the base plate by first hooking the room unit’s front to the top latches, and then rotating the cover downward until it latches. 4. Loosen the safety set screw at the bottom of the base one or two revolutions to lock the cover to the base. Be careful not to loosen too far as the screw can be completely removed from the base. Electrical Box and Rough-in Mounting, Typical 1. If a locator is attached to the rough-in device, remove the locator by removing the two screws and lightly rocking the locator to pull it free. 2. Untie the twist tie and pull about three inches (75 mm) of the room unit cable through the hole in the base plate. 3. Mount the room unit base plate on the wall, noting theUP arrow: NOTE:If required, position the back plate behind the room unit base, aligning the top and bottom mounting holes, prior to mounting to the wall: a. Install the two room unit mounting screws provided, but do not tighten. b. Level the room unit base plate for appearance only. c. Tighten the two mounting screws to the room unit base plate. CAUTION: Over-tightening may cause the room unit base plate to crack or bend. 4.

If the room unit is powered by isolated DC: • Where power is current limited up to 300 mA, it is not required to earth ground the controller isolated common. • Room unit DC-(GND) must be connected to the controller common. CAUTION: Follow manufacturer’s Installation Instructions and Wiring Guidelines for connecting the controller to the room unit. For Siemens Controllers: • APOGEE Controllers with common already earth grounded are TXIO used on PXC Modular, PXC Compact 36 Expansion and P1 BIM or PTM used on MBC and RBC. These do not require the earth ground wire to be connected to the controller. • APOGEE Controllers with floating common are PXC Compact 16/24/36, MEC, PXM, LON TEC and PPM. These require the earth ground wire to be connected to the controller. Figure 6. Typical Wiring Base. (All terminals may not be present.) NOTE:If active temperature (0 to 5V/0 to 10V/4 to 20 mA) (Pin 3) rather than passive/resistive temperature is used, Passive Temp Common (Pin 6) does not need to be terminated.
