My thermostat has just two cables. Am I appropriate for ecobee? | Купить бетон в Солнечногорске с доставкой по низкой цене

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

Prior to starting out, take note the annotated following:

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

To ascertain compatibility, you will want to access both the wiring at your thermoregulator along with the wiring at your home heating where in actuality the thermoregulator wiring comes to an end.

You can reach out to ecobee support for guidance, or hire a technician to aid in installation if you are not comfortable doing so

  • According to what amount of free cables you have got behind the wall surface during the thermoregulator, a few of these choices will demand extra elements that aren’t incorporated with the ecobee, including operating 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 wires that are extra have actually behind your wall in the thermoregulator

    Eliminate your thermostat from the wall surface to see any unused cables which are perhaps perhaps maybe not presently linked to your thermoregulator. Be sure to always check behind the wall during the thermoregulator also. In many cases, the wire bundle during the thermoregulator will contain sigbificantly more than two cables total, with many unused cables designed for usage.

    Note this number down and continue to step three.

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

    The step that is next confirming exactly what your thermostat cables connect with at your heating gear.

    Put in writing the wiring tints at your thermoregulator as well as the forms of terminals they truly are linked to. Next, find your thermoregulator wires at your heating gear. You will need to find the part of that the two low-voltage thermostat wires join up together with your equipment.

    With regards to the make and model of the gear, your thermoregulator wires may hook up to the annotated following:

    • Wiring terminals such as for instance R, W, and C at your furnace
    • A gasoline valve with terminals such as for example Th, Tr, and Th-Tr
    • T/T connections, usually linked to an Aquastat

    Scenario A:MY THERMOSTAT LINKS TO R AND W

    When your thermostat cables connect with terminals marked R and W, installation can be as straightforward as linking a 3rd cable into mail order brides the typical from the furnace or boiler’s low-voltage point that is common. Dependent on your furnace, this can be either a terminal marked «C» or «Com 24V», or perhaps you may want to find where in actuality the popular could be linked to.

    Every furnace and boiler that features a 24vac transformer will have a typical terminal—just trace the 2 low-voltage wires to check out where they hook up to. If you have a preexisting connection point, then touch the C cable from the thermoregulator only at that point. Often cutting/stripping the common cable for splicing the thermoregulator’s C cable are often needed.

    IF AN EXTRA is had by you CABLE

    Simply link the free cable into the connection point that is common.

    IF YOU’VE 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

    ALTERNATE SOLUTION: 24VAC PLUG-IN TRANSFORMER

    A different is to power the ecobee having an outside 24VAC plug-in transformer. This transformer is connected to a wall surface, and could be wired the following:

    • The 24VAC transformer cables would connect with RC and C regarding the ecobee
    • The 2 cables in your old thermostat would connect with RH and W1 in the ecobee

    NOTE: Ensure the transformer is capable of 24V AC production ( perhaps maybe not DC production)
