My thermostat has just two cables. Am I suitable for ecobee?

ecobee thermostats require a C (popular) wire to energy on. In case your current thermoregulator uses just two cables (R and W, or T and T), you will find a few installation choices available, according to ۳۲۱chat the job.

Prior to starting out, take note the annotated following:

    You simply will not have the ability to install the Power Extender Kit (PEK) with heat-only systems that are 2-wire. The PEK can only just be applied on furnace or temperature pump systems which do not have C cable — it is because the PEK calls for R (energy), G (fan), and Y (compressor) wires to use, and these 2-wire systems that are heat-only not need these G and Y wires

To find out compatibility, you shall have to access both the wiring at your thermoregulator along with the wiring at your home heating in which the thermoregulator wiring finishes. You can reach out to ecobee support for guidance, or hire a technician to aid in installation if you are not comfortable doing so

  • Dependent on exactly how many free cables you have got behind the wall surface during the thermoregulator, several of those choices will demand additional elements that aren’t added to the ecobee, including operating brand new cables and/or buying an external 24VAC transformer, SP/NO isolation relay, or Fast-Stat Common Maker
  • ACTION 1:DETERMINE EXACTLY HOW MANY THERMOSTATS YOU HAVE CONTROLLING YOUR HEATING SYSTEM

    When you yourself have one thermostat managing your heating system, continue to step two below.

    Action 2:Determine how many additional cables you have actually behind your wall surface during the thermoregulator

    Eliminate your thermoregulator from the wall surface to check out any unused cables being perhaps maybe perhaps not presently attached to your thermoregulator. Make sure to always check behind the wall surface during the thermoregulator aswell. The wire bundle at the thermostat will contain more than two wires total, with numerous unused wires available for use in some cases.

    Note this quantity down and continue to step three.

    Action 3:Determine just what wiring terminals you’ve got on your own home heating

    The next thing involves confirming exactly what your thermostat cables connect with at your heating gear.

    Put in writing the wiring tints at your thermostat plus the forms of terminals they’ve been attached to. Next, find your thermoregulator wires at your heating gear. You will need to locate the true part of that the two low-voltage thermostat wires join up along with your gear.

    With respect to the make and model of one’s equipment, your thermoregulator wires may connect with the following:

    • Wiring terminals such as for example R, W, and C at your furnace
    • A gas valve with terminals such as for example Th, Tr, and Th-Tr
    • T/T connections, frequently attached to an Aquastat

    Situation A:MY THERMOSTAT LINKS TO R AND W

    When your thermostat cables connect with terminals marked R and W, installation can be straightforward as linking a third wire to your typical in the furnace or boiler’s low-voltage point that is common. Based on your furnace, this can be either a terminal marked “C” or “Com 24V”, or perhaps you may should find in which the popular could be attached to.

    Every furnace and boiler which includes a transformer that is 24vac have a standard terminal—just trace the 2 low-voltage wires to discover where they hook up to. If you have a current connection point, then touch the C cable from the thermoregulator only at that point.

    Often cutting/stripping the wire that is common splicing the thermoregulator’s C cable are often needed.

    IF AN EXTRA is had by you CABLE

    Merely link the extra cable towards the connection point that is common.

    IF YOU HAVE GOT NO ADDITIONAL WIRES

    You have two options if you do not have any additional wires:

    • Run a extra cable at your thermoregulator down to your gear
    • Buy and install a Fast-Stat Common Maker
