ecobee thermostats require a C (popular) wire to power on. In case the current thermoregulator utilizes just two cables (R and W, or T and T), you will find an installation that is few available, based on the application.
Prior to starting out, take note the immediate following:
You’ll not have the ability to install the Power Extender Kit (PEK) with heat-only 2-wire systems. The PEK can just only be utilized on furnace or temperature pump systems that don’t have a C cable вЂ” it is because the PEK calls for R (energy), G (fan), and Y (compressor) cables to use, and these 2-wire heat-only systems do n’t have these G and Y cables
To find out compatibility, you shall want to access both the wiring at your thermoregulator along with the wiring at your home heating where in fact the thermoregulator wiring finishes.
