Heat Pump Controller Single Stage. Control Applications Accessories 2070 through 2072 Product Description P25 (pack of 25) Low cost temporary temperature sensor that enables space control if the permanent room or duct sensor is not installed. These instructions explain how to field install or replace a Heat Pump Controller Single Stage (for single and dual compressor heat pump applications). Product Numbers Heat Pump Controller Single Stage Shipping carton includes a controller assembly, mounting rail, and two self-tapping screws. Keep the unit in its static-proof bag until installation. Parts for C Compliance: Clamp-on ferrite filter (10 pack) series Approved 2-RJ11 RTS cable in 25, 50, or 100 (7.6-m, 15.2-m, m) Metal Small quipment Controller nclosure Large quipment Controller nclosure Warning/Caution Notations WARNING: Personal injury/loss of life may occur if you do not follow the procedures as specified.

2 quipment damage or loss of data may occur if you do not follow the procedures as specified. xpected Installation Times 10 minutes minutes. Required Tools and Materials Flat-blade screwdriver (1/8-inch blade width). Small flat-blade screwdriver Cabling and connectors. See the section. Cordless drill/driver set Prerequisites Wiring conforms to NC and local codes and regulations. For further information refer to the Wiring Guidelines manual ( ). 24 Vac Class II power source available. Supply power to the controller is OFF. Any application specific hardware or devices installed. Room temperature sensor installed (optional). (If desired, a low-cost temporary temperature sensor is available that plugs into the RTS port of the TC (P/N P25), providing temperature input and actual space control until the permanent room or duct sensor is installed.) If the controller is being installed on a box with 1 or more stages of electric heat, the MOV with pre-terminated spade connectors must be installed across the manufacturer-supplied airflow switch. MOVscanbeinstalledatthetimethe Instructions controller is factory mounted; coordinate with the box manufacturer prior to order placement. For field installation, see Metal Oxide Varistor Kit ( ). All wiring must conform to NC and local codes and regulations. 1. Secure the mounting rail (Figure 1) in the controller s desired location. 2. Place the SD wrist strap on your wrist and attach it to a good earth ground. 3. Remove the controller from the static proof bag and snap it into place on the mounting rail. 4. Connect the FLN (Figure 2). TC0470R1 (SHILD) Figure 2. FLN + - S (-) (-) (+) (+) FLN Wiring. Do not ground the shield. (SHILD) 5. Connect the point wiring (see Wiring Diagrams). 6. Plug the room temperature sensor cable into the RTS port (Figure 1). 7. Connect the power trunk (Figure 3). DO NOT apply power to the controller. Page 2 of 6 Siemens Building Technologies, Inc.

3 POWR GRND WHN THIRD TR- MINATION IS PRSNT approximately 1 cm from the end of the cable being shielded (RTS cable[and the point wiring for AI3]) (Figure 4). 1 Place the filter 1-2 cm from the end of the cable or wiring to be shielded. 1-2 cm TC0471R1 Figure 3. GRND 24 V HOT 24 V COMMON Power Trunk Wiring. 2 Wind the cable tightly twice around the filter. As a standard grounding procedure, ensure that 3"-5" ground wire is connected directly on the common terminal on the secondary side of the 24 Vac transformer. The installation is complete. C Compliance If C compliance is required, the quipment Controller must be mounted in a grounded metal enclosure and a ferrite filter must be placed 3 TC0320R3 Close the filter and wrap with a zip tie.
