INSTALLING THE SMART THERMOSTATThere are ve steps to installing the ecobee Smart Thermostat:Step 1: Install the Equipment Interface.Step 2: Wire the Equipment Interface.Step 3: Install the Smart Thermostat.Step 4: Connect the Smart Thermostat to the Equipment Interface.Step 5: Power up both devices.Installing the Equipment Interface To install the Equipment interface:In the homeowner’s utility room or basement, select a suitable location either on a wall or on the cold air return plenum. Make sure that there is an electrical outlet within ve feet of where you plan to mount the device.Note: Do not mount the device on the supply plenum or anywhere inside the heating or air conditioning equipment.Remove the front cover of the Equipment Interface. Insert a at-head screwdriver into one of the slots as shown below, and gently twist the screwdriver.Insert a screwdriver into one of the two slots and twist gently1.2.9The LEDs operate as follows:PowerThis LED monitors the power supply of the Equipment Interface. LED On Power is connected to the Equipment Interface and is within the appropriate voltage range.LED O Power is disconnected or has dropped below 9V.SystemThis LED monitors the operation of the Equipment Interface andthe connection between the W and Y terminals to their respective connections on the heating and cooling control board.LED On There is a fault with the Equipment Interface or the wiring to the heating or cooling equipment. LED O The equipment is operational and there is connection to the heat and/or cool relay outputs (W or Y).LineThis LED monitors the power supplied to the Smart Thermostat from the Equipment Interface.LED ON The voltage at the +12V and GND terminal has dropped below 7V.LED O Adequate power is being supplied to the Smart Thermostat.CommunicationsThis LED monitors the communications between the Smart Thermostat and the Equipment Interface (i.e., the D+ and D- terminals).LED On The Equipment Interface and Smart Thermostat are not communicating to each other.LED O The two devices are communicating properly.18
Connecting power Once you’ve completed the wiring of the Smart Thermostat and Equipment Interface, you can apply power to the Equipment Interface and restore power to the heating and air conditioning equipment. To power up the ecobee Smart Thermostat and Equipment interface system, plug the power supply into a standard electrical outlet and plug the barrel connector into the Equipment Interface.Equipment Interface Status LEDThe Equipment Interface has four LEDs to display the statusof the system. If you’ve wired the system correctly, only the Power LED should be on. 17Plug the adaptor into the equipment interfacePlug the adaptor into the equipment interfacePowerSystemLineCommunication3.4.5.6.1.2.3.4.5.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. 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.Use drywall plugs or other screw anchors (not included) to ensure the Equipment Interface can be mounted securely on the intended surface.Fasten the backplate to the wall using the appropriate screws (not included). Wiring the Equipment InterfaceTo wire the Equipment Interface:Disconnect the power to the heating and air conditioning equipment.Disconnect the wires going to the existing thermostat.Using the wiring diagrams below, connect the heating or air conditioning equipment to the Equipment Interface.Do not apply power until you have installed and connected the Smart Thermostat. (see instructions below)Do not install the front cover on the Equipment Interface at this point.10Mounting holes indicated with solid colour
