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

In case your thermostat cables connect with terminals marked Th, Tr, and Th-Tr, they truly are most likely connecting to a gas valve.

Nevertheless, you will have to locate the cables linking to your gasoline valve and follow them to your transformer that is 24VAC the heating gear to determine where your « C » connection may be. In the event that you need help with this, be sure to contact ecobee help.

Merely link the free cable to your connection point that is common.

IF NO EXTRA is had by you WIRES

If you fail to have any additional wires, 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 PLUG-IN TRANSFORMER

A different is always to power the ecobee having an outside plug-in transformer that is 24VAC.

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

  • The 24VAC transformer cables would connect with RC and C in the ecobee
  • The two wires in your old thermostat would connect with RH and W1 in the ecobee

NOTE: Ensure the transformer can perform 24V AC production ( perhaps perhaps not DC production)

Situation C:MY THERMOSTAT LINKS TO T/T TERMINALS

When your thermostat cables hook up to T/T terminals, keep in mind that you will need an independent 24VAC transformer to power the ecobee. It’s also possible to need components that are additional.

T/T connections frequently suggest a link to a tool called an Aquastat.

IF YOU’VE GOT A SUPPLEMENTARY WIRE

For those who have a supplementary cable, you’ll need an isolation relay and an independent 24VAC transformer.

ecobee calls for an isolation relay by having a 24vac coil and Normally Open (N/O) connections.
