In case your thermostat cables hook up to terminals marked Th, Tr, and Th-Tr, they truly are most most likely connecting to a gasoline valve.
But, it is important to locate the wires linking towards the gasoline valve and follow them into the transformer that is 24VAC the heating gear to spot where your “C” connection should be. In the event that you need assistance with this, be sure to contact ecobee help.
Merely link the free cable towards the typical connection point.
IF YOU’VE GOT NO ADDITIONAL WIRES
Should you not have any extra cables, you’ve got two choices:
- Run a extra cable at your thermoregulator down to your gear
- Buy and put in a Fast-Stat Common Maker
ALTERNATE SOLUTION: 24VAC TRANSFORMER that is PLUG-IN
A different would be to power the ecobee by having an outside plug-in transformer that is 24VAC.
This transformer could be attached to a wall surface, and could be wired the following:
- The 24VAC transformer cables would connect with RC and C from the ecobee
- The two cables in your old thermostat would connect with RH and W1 in the ecobee
