In case your thermostat cables connect with terminals marked Th, Tr, and Th-Tr, they’re most likely connecting to a gas valve.
Nevertheless, it is important to locate the cables linking to your gasoline valve and follow them to your 24VAC transformer for the heating gear to spot where your “C” connection will likely be. In the event that you need advice about this, be sure to contact ecobee help.
Merely link the extra cable to your 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 wire that is additional 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 is always to power the ecobee with an outside plug-in transformer that is 24VAC.
This transformer are connected to a wall, and will be wired the following:
- The transformer that is 24VAC would hook up to RC and C from the ecobee
- The 2 cables on your own old thermostat would connect with RH mail order bride org and W1 regarding the ecobee
NOTE: make sure the transformer is with the capacity of 24V AC production ( maybe maybe not DC production)
Situation C:MY THERMOSTAT LINKS TO T/T TERMINALS
When your thermostat wires connect with T/T terminals, observe that you’ll need a different transformer that is 24VAC power the ecobee. You may even need components that are additional.
T/T connections usually suggest an association to a tool referred to as an Aquastat.
IF AN EXTRA is had by you CABLE
When you have an additional cable, you’ll need an isolation relay and a different 24VAC transformer.
ecobee calls for an isolation relay with a coil that is 24vac Normally Open (N/O) connections.
IF YOU’VE GOT NO ADDITIONAL WIRES
When you yourself have no additional cables, you may need both a Fast-Stat Common Maker and a split 24VAC transformer
