Getting Started with the EMS


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.

 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 Begin


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 Thermostat senses temperature, displays information and, if enabled, allows users to make adjustments directly on the touch screen.

 2.  The Equipment Interface Module provides power to the Thermostat and is the interface for all of the HVAC 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.

 Caution: Disconnect electric power to the system before installing this product. Failure to do so could result in electric shock and/or equipment damage. 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.
