When your thermostat wires connect with terminals marked Th, Tr, and Th-Tr, they truly are most likely connecting to a fuel valve.
Nevertheless, you will have to locate the cables linking towards the fuel valve and follow them into the transformer that is 24VAC the heating equipment to recognize where your “C” connection is going to be. In the event that you need help with this, be sure to contact ecobee help.
Simply connect the free wire to your common connection point.
IF YOU’VE GOT NO ADDITIONAL WIRES
If you don’t 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 find-bride SOLUTION: 24VAC TRANSFORMER that is PLUG-IN
Another solution would be to power the ecobee with an outside plug-in transformer that is 24VAC.
This transformer may be connected to a wall, and is wired the following:
- The transformer that is 24VAC would connect with RC and C in the ecobee
- The 2 wires on your own old thermostat would connect with RH and W1 in the ecobee
NOTE: make sure the transformer is with the capacity of 24V AC production ( perhaps perhaps not DC production)
Situation C:MY THERMOSTAT LINKS TO T/T TERMINALS
In case your thermostat wires connect with T/T terminals, keep in mind that you will need a different 24VAC transformer to power the ecobee. You may even need components that are additional.
T/T connections frequently indicate an association to a tool referred to as an Aquastat.
IF YOU HAVE GOT A SUPPLEMENTARY CABLE
For those who have an additional cable, you’ll need an isolation relay and a different 24VAC transformer.
ecobee calls for an isolation relay with a 24vac coil and Normally Open (N/O) associates.
IF NO EXTRA is had by you WIRES
When you have no extra cables, you may need both a Fast-Stat popular Maker and an independent 24VAC transformer
ALTERNATE SOLUTION: 24VAC TRANSFORMER that is PLUG-IN
Another solution would be to power the ecobee with a outside 24VAC plug-in transformer.
This transformer could 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 cables on your own old thermostat would connect with RH and W1 in the ecobee
NOTE: make sure the transformer can perform 24V AC production ( perhaps maybe not DC production)
NOTE (2): Some T/T connections might not work reliably whenever connected straight to the Rh and W1 terminals associated with ecobee. A 24 VAC transformer and isolation relay on the equipment side would be necessary (see details under “IF YOU HAVE AN EXTRA WIRE” above) in that case.
When you have a couple of thermostats managing your heat:
If the home heating is managed by a lot more than one thermoregulator, the body most most most likely has area valves or even an area control relay.
Please touch base to ecobee help aided by the after information in order to ascertain compatibility and appropriate installation directions:
- just exactly How numerous thermostats you have actually as a whole for the home heating
- Photos for the wiring at each thermostat
- Photos of this wiring at any area valves or area boards
- The make and model of every area valve and/or area panels
- The amount of additional wires which are behind the wall at each thermostat
If you should be having trouble distinguishing your area valves or zone panels, some widely used manufacturers for area valves/zone control gear consist of:
- Taco
- Honeywell
- Erie
- Energy Kinetics
