Ecobee Rc And Rh

If you have a jumper between rc, rh or r, leave it alone. Only label the wires that run from your wall into a terminal block.

It's a live electrical wire.

Ecobee rc and rh. Gently tug on each wire to ensure they are snuggly inserted. Just figured out that heat doesn't work because when we had some radiator work they turned off the valve to the aquatherm. In order to power the thermostat, the r/rc/rh wire must be connected to the rc terminal.

W2, aux and or e (emergency) wiring connections will normally connect to the ecobee3 w1 terminal. When the ecobee was plugged in, it would click and i would see the screen flash but then no power after that. I'm about to replace my honeywell thermostat (rth8500) with an ecobee 3.

Make sure to select rc only and not rc and rh during this configuration process. /w1 /y1 c rc rh. Before getting started, please note the following:

If you don't have an rc wire, rh serves as both the heating and cooling power wire. Ensure your power is turned on from the circuit breaker. This is true for all ecobee thermostats except the ecobee3 lite.

Yes, but only if the control board has separate terminals for rc and rh. Original thermostat was wired to rh and then jumpered to rc. If you don't have an rh wire, rc serves.

Connect wires to ecobee3 the wires from the wall should plug easily into the terminal blocks. Thanks for all the info. Once your ecobee powers up, you will be asked to configure your equipment.

If both wires are connected to the only r terminal, then doing what i suggested won't affect your ac; Label reading 110, 120, or 240 volts. Terminals listed as l1 or l2.

If you see any of the following indicators on your thermostat's backplate it means you have a high voltage system: With this configuration, the ecobee will automatically assume you have a boiler and a different heating algorithm will be used. When you break this down, it means that you'll traditionally have two r wires that each have different purposes.

Some hvac equipment have a safety switch that cuts power off if the cover panel isn't shut properly. Ecobee thermostats are not compatible with high voltage systems.

Here's what you'll find in the box: I connect my heating only zone setup to rc to get it to power on. The rc wire connects to.

To release a wire, press down on the lever. Just make sure that your ecobee in configured for both heat and ac, but knows that only your rh terminal is connected. My ecobee doesn't receive power with a connection to rh only;

When i wired up the ecobee, i hooked up r to rh. Your ecobee will detect rc, w1, and c. Rc or rh) wire must connect to the rc terminal on the ecobee3, or the thermostat will not power on.

Check that all wires are inserted into the correct terminal (both the wires and terminals are labeled). When installed correctly, the release lever of the terminal block will lower to indicate engagement. View examples of these indicators.

If the wire is in the rh terminal, the ecobee will not power up. After talking to tech support, they suggested switching the r wire to rc instead of rh which indeed powered it up fine. Make sure the r wire (either r, rc, or rh) is going to the rc terminal only.

If your current thermostat uses only two wires (r and w, or t and t), there are a few installation options available, depending on your application. One governs heating, and the other regulates cooling, hence rc and rh. Today, the honeywell is connected as follows:

As well, there is a c (common) terminal on the furnace circuit board which is not currently connected by wire to the thermostat. Rc is no different and simply means red cooling. Ecobee thermostats require a c (common) wire to power on.
