1 Document No EcoView Thermostat Product Description This document covers the installation and commissioning of the EcoView thermostat and sensors components the EcoView system. See the following documents for installation of other EcoView system components: EcoView 8 DO Module Installation and Commissioning ( ) EcoView Multi-Phase Meter Installation Instructions ( ) EcoView Touchscreen Installation and Commissioning ( ) Product Number EcoView Thermostat Caution Notations CAUTION: Required Tools Screwdriver Electric drill Equipment damage or loss of data may occur if you do not follow the procedures as specified. 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. COM is typically the blue wire, although on some thermostats it can be a black wire. 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. Expected Installation Time 15 minutes CAUTION: 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. Figure 1. Thermostat Base Plate. If 24 Vac was present at the thermostat, skip Step 3 and proceed to Step 4.

Remote Sensor Run the remote sensor wires from the sensor to the two terminals marked RSI on the thermostat base plate (see Figure 1), through the same hole as the existing thermostat wires. 3. Keep the wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts, and distribution panels. Shielded cable is required in all installations. Use cable similar to a Belden DFLEX3, and attach the shield to 24C on the thermostat base plate (see Figure 1). Leave the other end of the shield unattached. Refrigeration Sensors Refrigeration sensors are an option, and are installed in the same manner as the remote sensors. 1. The refrigeration sensor is the same as the remote sensor. It has two wires. These wires are not polarized, and may be interchanged. 2. Run the refrigeration sensor wires from the sensor to the two terminals marked on the thermostat base plate (see Figure 1) through the same hole as the existing thermostat wires. 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. Shielded cable is required in all installations. Use cable similar to a Belden DFLEX3, and attach the shield to 24C on the thermostat base plate (see Figure 1). Leave the other end of the shield unattached. Page 3 of 7
