Ecobee EMS Installation guide

Ecobee EMS system connections diagram
The ecobee Energy Management System (EMS) is the newest technology designed for the commercial market.It is ideal in applications where a simple programmable Thermostat does not provide adequate controls and functionality and a full-scale building automation system is too complex and cost prohibitive. The ecobee EMS is user friendly, reduces a building’s operating costs and delivers increased energy conservation. Download Ecobee EMS system connections diagram

Ecobee ENERGY MANAGEMENT SYSTEM Manual
Through a dedicated EMS Web Portal, users can remotely monitor, identify, analyze and trouble-shoot performance issues; manage the temperature and operational settings from a central location and take action without having to send a technician on-site, reducing the need for truck rolls. The ecobee EMS will maximize any building’s efficiency, reduce energy consumption and deliver significant cost savings.

Before You Installing the ecobee Thermostat
This product is intended to be installed by trained service professionals. This manual explains the procedures for installing the ecobee Energy Management System (EMS). Please read it carefully before beginning the installation. The ecobee EMS consists of two pieces of hardware:

1. The ecobee Thermostatsenses temperature,displays information and, if enabled, allows users tomake adjustments directly on the touch screen.
2. The Equipment Interface Moduleprovides powerto the Thermostat and is the interface for all of theHVAC equipment.

An optional 12 VDC power adaptor can be plugged into the Thermostat for product demonstrations or to power the Equipment Interface module in place of the normal 24Vac configuration.

All wiring must conform to your local electrical code.Mercury Notice: This product does not contain mercury. If you are replacing a product that does contain mercury please contact your local waste-management authority for disposal instructions. Do not discard the old product in the regular trash. HVAC System Compatibility Information ecobee Energy Management System is designed to operate low-voltage heating and cooling systems. Itis not designed for use with line-voltage or millivolt heating and cooling systems.

INSTALLING THE ECOBEE SYSTEM
Planning the Installation
Prior to installing the ecobee EMS, we recommend that you consider the following:
Where is the ideal location to mount theEquipment Interface?

• On a relatively flat surface
• In an environment that does not exceed the temperature or humidity level outlined in the specification section of this manual.
• In a location that is within the maximum wiring distance of the HVAC equipment and the Thermostat.
• How do I intend to power the ecobee Energy Management System?
• Does the HVAC system control board have enough spare capacity to power this system?
• Do I need to provide a 24Vac transformer?
• Do I have access to a 120V electrical output to use the optional 12Vdc power adapter?

Where is the optimum location for the Thermostat?

• Within the maximum wiring distance to the Equipment Interface.
• Receiving good reception of WiFi signal (3 bars or more) from the location.
• If WiFi reception is sub-optimal, what will berelocated, the Thermostat or WiFi router?
• Do the temperature and humidity levels adequately represent the area controlled by the HVAC system?

How is the WiFi and Internet connection configured in this building?

• Do I have access to the customer’s WiFi and/or internet connection?
• What information do I need to provide to the IT staffto ensure the ecobee EMS can successfully connect to their WiFi and/or internet connection?

Once you have planned your installation continue with the installation instructions.

Installing the Equipment Interface
To install the Equipment Interface:

1. Choose a suitable location to mount the Equipment Interface as determined fromPlanning the Installsection on page 7.
2. Remove the front cover of the Equipment Interface. If necessary, insert a flat-head screwdriver into one of the slots as shown below, and gently twist the screwdriver.
3. Place the back of the enclosure on the intended mounting surface and use it as a template to mark the location of the mounting holes as shown below.
4. Move the back of the enclosure out of the way and make the holes where indicated in step 3. The mounting holes can accommodate a #6 pan-head screw.
5. Use drywall plugs or other screw anchors (not included) to ensure the Equipment Interface can be mounted securely.
6. Fasten the backplate to the wall using the appropriate screws (not included).

Wiring the Equipment Interface
To wire the Equipment Interface:

1. Disconnect the power to the HVAC equipment.
2. Disconnect the wires going to the existing Thermostat.
3. Follow the wiring diagrams on pages 10-15, connect the HVAC equipment to the Equipment Interface.
4. Do not apply power until you have installed and connected the Thermostat. (see pages 17-19)
5. Do not install the front cover on the Equipment Interface at this point.
