ecobee thermostats require a C (popular) wire to energy on. If the current thermoregulator utilizes just two cables (R and W, or T and T), you can find an installation that is few available, dependent on the job.
Before starting, please note the annotated following:
To ascertain compatibility, you shall need to access both the wiring at your thermoregulator along with the wiring at your home heating in which the thermoregulator wiring concludes.
For those who have one thermostat managing your heating system, continue to step two below.
Eliminate your thermoregulator from the wall surface to check out any unused cables which can be maybe not presently linked to your thermoregulator. Make sure to check always behind the wall surface during the thermoregulator aswell. In many cases, the cable bundle during the thermoregulator will contain much more than two cables total, with many unused cables readily available for usage.
Note this true quantity down and continue to step three.
The next thing involves confirming exactly what your thermostat cables connect with at your heating gear.
Make a note of the wiring colours at your thermoregulator together with kinds of terminals they have been linked to. Next, find your thermoregulator wires at your heating gear. You’ll want to find the true part of which the two low-voltage thermostat wires join up together with your gear.
According to the make and model of one’s gear, your thermoregulator wires may hook up to the immediate following:
Situation A:MY THERMOSTAT LINKS TO R AND W
In case your thermostat cables connect with terminals marked R and W, installation can be straightforward as linking a 3rd cable to your typical regarding the furnace or boiler’s low-voltage point that is common. According to your furnace, this can be either a terminal marked “C” or “Com 24V”, or perhaps you might have to find where in fact the popular may be linked to.
Every furnace and boiler who has a 24vac transformer will have a standard terminalвЂ”just trace the 2 low-voltage wires to check out where they connect with. If you have a preexisting connection point, then touch the C cable from the thermoregulator only at that point. Often cutting/stripping the wire that is common splicing the thermostat’s C cable are often needed.
IF YOU’VE GOT A SUPPLEMENTARY CABLE
Merely link the free cable to your connection point that is common.
IF YOU HAVE GOT NO ADDITIONAL WIRES
ALTERNATE SOLUTION: 24VAC PLUG-IN TRANSFORMER
A different is always to power the ecobee having an outside 24VAC plug-in transformer. This transformer could be attached to a wall surface, and could be wired as follows:
NOTE: Ensure the transformer is with the capacity of 24V AC production ( perhaps perhaps not DC output)
