All temperature sensors require 18AWG- 22AWG twisted, shielded cable. The shield should be grounded on one end only. This thermostat is a direct replacement and should accept the same wires. However, if the AC unit is configured as a heat pump, there are settings that can be adjusted in the configuration menu on the thermostat. Remove the existing thermostat before proceeding. Ensure that there is 24 Vac present at the COM and RH terminals. If it is not present, ensure that it is run from the HVAC unit. Installation 1. Remove the base plate from the thermostat housing by pulling straight up. 2. Install the thermostat base plate. a. Feed the existing wires through the opening in the base plate. b. Secure the base plate to the mounting surface using appropriate hardware. Required Tools Screwdriver Electric drill Expected Installation Time 15 minutes If thermostat security enclosures are required, they must be non-metallic so they will not interfere with the radio transmission. Prerequisites Power off the AC unit before attempting removal of the existing thermostat. Thermostat wires are typically color coded. If not, you must make note of which terminal designator each wire was attached to. NOTE: Figure 1. Thermostat Base Plate. If 24 Vac was present at the thermostat, skip Step 3 and proceed to Step If 24 Vac was not present at the thermostat: a) Locate the 24 Vac transformer or 24 Vac on the terminal strip typically located behind an access panel on the AC unit. Attach an unused thermostat wire to the 24 Vac return. b) Attach the other end of the unused wire to the thermostat RH or RC terminal. Item Number , Rev. CA Page 1 of 8

If this is not completed, the thermostats may not communicate properly. Figure 3. Remote Sensor Run the remote sensor wires from the sensor to the two terminals marked RS1 on the thermostat base plate (see Figure 1), through the same hole as the existing thermostat wires. When installed, the remote sensor on RS1 overrides the internal temperature sensor in the thermostat. 3. Keep the wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts, and distribution panels. 4. Keep remote sensors away from air diffusers, external doorways, and other areas where temperatures may fluctuate with airflow or door openings. Siemens Industry, Inc.

5 5. Locate the remote sensor in an area where it will accurately measure the average space temperature in the room. NOTE: Refrigeration Sensors If the space is large and cannot be accurately estimated by using a single remote sensor, install an additional remote sensor on the terminals of RS2. Once installed, from the Installer Settings screen, configure the Remote Sensors > RS2 Location setting to In. This ensures that it is averaged with RS1 to provide an accurate space temperature in the room. For detailed information about using the Installer Settings screen, see Thermostat Installer Settings (Hidden Screen). Refrigeration sensors are an option, and are installed in the same manner as the remote sensors. NOTE: The refrigeration sensor is the same as the remote sensor. It has two wires. These wires are not polarized, and may be interchanged. 1. Run the refrigeration sensor wires from the sensor to the two terminals marked RS2 on the thermostat base plate (see Figure 1) through the same hole as the existing thermostat wires. 2. From the Installer Settings screen of the thermostat, configure the Remote Sensors > RS2 Location setting to Out. This ensures reliable results by taking the sensor out of the RTU control sequence. For detailed information about using the Installer Settings screen, see Thermostat Installer Settings (Hidden Screen). 3. Locate the refrigeration sensor in the center of the walk-in freezer or refrigerator. 4. Run the wires by puncturing a small hole in the wall of the walk-in, and feeding the wires through. 5. Use silicone to completely seal the area around the wires. 6. Keep the wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts, and distribution panels. 7. Keep refrigeration sensors away from fans, doors, and other areas where temperatures may fluctuate with airflow or door openings. Siemens Industry, Inc. Page 5 of 8
