Situation B: MY THERMOSTAT LINKS TO TH/TR/TH-TR. IF AN EXTRA is had by you CABLE

In case your thermostat cables hook up to terminals marked Th, Tr, and Th-Tr, they truly are most most most likely connecting to a fuel valve.

But, you will have to locate the cables linking to your gasoline valve and follow them towards the 24VAC transformer for the heating gear to determine where your “C” connection will undoubtedly be. In the event that you need help with this, be sure to contact ecobee help.

Merely link the extra 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 put in a Fast-Stat Common Maker

ALTERNATE SOLUTION: 24VAC PLUG-IN TRANSFORMER

Another solution is always to power the ecobee having a outside 24VAC plug-in transformer.

This transformer is connected to a wall, and will be wired the following:

  • The transformer that is 24VAC would hook up to RC and C in the ecobee
  • The two cables on your own old thermostat would connect with RH and W1 from the ecobee

NOTE: make sure the transformer is with the capacity of 24V AC production ( perhaps perhaps not DC production)

Situation C:MY THERMOSTAT CONNECTS TO T/T TERMINALS

In case your thermostat cables hook up to T/T terminals, remember that you’ll need a different 24VAC transformer to power the ecobee. You may even need components that are additional.

T/T connections frequently suggest a link to a computer device referred to as an Aquastat.

IF YOU HAVE GOT A SUPPLEMENTARY WIRE

You will require an isolation relay and a separate 24VAC transformer if you have an extra wire.

ecobee calls for an isolation relay by having a coil that is 24vac Normally Open (N/O) associates. Continue reading Situation B: MY THERMOSTAT LINKS TO TH/TR/TH-TR. IF AN EXTRA is had by you CABLE
