For example using a RIBU1C, connect its 10-30 VAC coil with its Wht/Yel wire to C of the AC system and Wht/Blu to the ecobee's Y1. In heat pump systems, Y1 controls your compressor, which heats and cools your home. I installed the thermostat originally with the PEK (eveything worked minus the outside unit running, by the way we have a furnace) because I didn't think I had a C wire, but after pulling some of the wires behind the thermostat I think I have one (it's blue). I was just wondering if anyone knew if it would still work using the PEK. If you are not a member of the trade… Did you measure 10v on Y1 without the Ecobee connected? I will have to measure mine. I have a Y and a Y2. G is fan and is the green wire. Check out the list below. The HVAC unit will detect that 24v and turn on the cooling mode. Ok the Lennox is a communicating thermostat. R to Rc, Y to Y1, G to G. They are not compatible. Thank you! You spurred us to dig deeper and we solved the problem. Since new you can try returning to the store and swapping out the Nest. Make sure you have a C wire is attached to the C connector on your thermostat. I think my wiring is a little odd Here is how it was wired previously: Original wiring. Here are two primary problems often encountered. I'm in desperate need of help, I have an American Standard HVAC (TEM4A0B36S31SB) and Heat Pump units(4A6H4036G1000A). The technical reason this will not work is because you cannot /not/ have a "G" wire, because the thermostat is responsible for energizing this during a cooling call. Yellow and black were not connected to my perfectly working Nest. Then connect its N/O (normally open) output to the AC system: Yel to R and Org to Y. Also had it tell the ecobee I had a g wire to setup. Even though this issue is pretty rare, you will still notice a sudden drop in the performance of your HVAC system. It’s not a long run and should be easy. The new furnace was installed last week and the heat pump is going to be installed later today. Trane Y - Compressor in both heating and cooling = Ecobee Y - Cooling terminal. Otherwise if you can't add a C wire at the Nest then try adding a resistor at the furnace connecting the C and Y. The unit also has a spot for a g wire, the old thermostat just did it use it. I have a fairly simple setup compared with what I see some folks have here. The ecobee3s work properly when wired to the boiler. saying they don't like Ecobee. There were 5 wires plugged into the thermostat (I forgot to take photos!), which were W1, Y1, G, and R. Automatic versus Manual Threshold Staging: By default, ecobee thermostats will have the Configure Staging option set to Automatically. Like change it from “Rc and Rh” to “Rh only. Be sure to test both heating and AC or you might have a surprise when the seasons change. The tech said that the lack of G means the blower does not start prior to the condenser starting so it turns on but then turns off. Does not take much to blow a fuse on a control board. That "type" of hold will not be changed by the schedule, even though you have your "hold mode" preference set to "until next scheduled event". I know there should be two more wires for the A/C unit - one to C and one to Y1 but that is not the case. If you Google it you will see that the “C” terminal is beside the “R” terminal, so it looks like that blue is on “C” and if it goes up in the bundle to the thermostat you should be good to go to use that as your “C” on the Ecobee. The equipment in play is: Ecobee by Bryant Smart Thermostat; 38MURA Bryant Heat Pump; Amana AMVC96 Gas Furnace; Wiring: Thermostat -> Furnace; Rc -> R (outdoor unit also tied in with wire nut) G -> G I just replaced my Honeywell thermostat - everything was working. The full wiring is Ecobee <-> Cooler W2 <-> W Y1 <-> Y R <-> Rc G <-> G What we are now seeing as a result is that the Ecobee 3 sees the system as a one-stage air conditioner, and it operates in the following manner. It is working better than Nest, furnace fan is quiet at Y1 and blasting at Y2. By default, ecobee engages heating when the temperature drops 0. Manually add the Y1 terminal so that it’s highlighted. 1. With the Ecobee we transfered all the wires like we found them, except that we got rid of the jumper connecting Y1 to W1 and then we moved W2 (single stage furnace) to W1 on the Ecobee. Go to Main Menu > General > Settings > Installation Settings > Thresholds. What equipment does it think you have? The g wire is for the fan in the unit not for cooling. It’s even more frustrating when the thermostat was already working and suddenly loses power. I had written ecobee and this is what they wrote back, in case it is helpful. First verify that the wires are firmly connected behind the ecobee but tugging gently to make sure they are not loose. You just lose thermostat control of the fan. My setup is a heat pump outside (old Trane XE900) and some form of air handler inside. I'm just a homeowner, not HVAC tech, so take all of this with a grain of salt. "The ecobee can take anywhere from 24-29vAC from your HVAC unit. You need to verify that all the wiring and voltages are correct. In conventional cooling systems, Y/Y1 controls the first stage of cooling and Y2 controls the second stage, which helps cool down the home faster. Little more backstory: I’m trying to replace a battery-powered thermostat with this Ecobee. I would repurpose the C conductor as a separate W1 conductor at both the thermostat and furnace control board. Changing the wiring for AC as shown here does not work (I removed the white wire and placed it in Y2, in Y1 very hot air comes). I needed to add the PEK at the HVAC control board. Both recommended replacing the thermostat. R to Rc (red) G to G (green) Aux to W1 (white) Y to Y1 (yellow) B to O/B (brown) C to C (blue) My heat pump has been working just fine until now (with my old honeywell) but when the ecobee calls for heat only the fan will turn on. How to Fix Ecobee Aux Heat Not Working? Check Heat Thresholds Jan 11, 2024 · I previously had 2 dumb thermostats. There is light air that comes but the outside unit/ compressor does not turn on. You just have to love PCs. Make sure it's in properly and if it's a fuses type the fuses are good. The Ecobee has the ability to control the fan instead of the furnace controlling the fan. If you install it, test the heat, and just cool air blows out then try setting the valve to energize the other way. Two Pek on each zone of the zone board to feed back to each thermostat on that furnace. The other side goes into the wire cap that currently has two wires in it already. See full list on robotpoweredhome. If you have no spares, install the Power Extender Kit (PEK). gnxaliy hftej rfrudn unnhr gfrr nhjt xiqdwve itobpa wfrz aqay
