Excellent ecobee 4 wiring diagram - 3 years in the past i purchased a carrier 58mvc (3 degree warmness variable velocity fan) and easy unmarried degree ac condenser. It's a pleasant unit and has genuinely made a fantastic impact to the comfort of my domestic. It's been hooked up to a "dumb" programmable thermostat. I completely remember that i is probably giving up some capability by using going with the ecobee vs a service infinity thermostat. That stated i think it's greater than i'm getting currently. If you’re already using a power extender package (pek) with the ecobee3, you’ll want to perform a little re-wiring on the ecobee4. The r twine will cross into the rc terminal, the g wire into the c terminal, and the y wire into the pek terminal on the ecobee4. Remaining wires will pass into the respective terminals. The ecobee4 makes use of the identical pek as the ecobee3 lite. So in case you're shifting from ecobee3 lite to ecobee4 and are the use of the pek, then you may just cord it the same, the r to rc, the g cord to c and the y cord to pek.
Here are applicable pix, i also have new 7 conductor thermostat cmr rated thermostat wire so that i'm able to fish new twine due to the fact my vintage one is spliced to shit. Proposed ecobee wiring there may be an error right here, y2 ought to be w2. I'd use the 7 conductor to wire up the furnace, and then a separate 2 conductor to cord up the humidifier. I would also need to discern out which dip switch(es) i'd want to lively a 2d level of heat at the furnace. So am i near, or have to i simply call my hvac man?. I have an ecobee3 thermostat that i would love to hook up with the system as well as deliver manage of complete house humidifier (popular aire 1137) to the thermostat or furnace. The humidifier is presently managed via a humidistat this is reduce into the main return air duct right earlier than it enters the fanbox.
