Best honeywell th9421c1004 wiring diagram - So what i've is for the excessive performance furnace? Is that what you meant by way of "unique excessive furnaces"? I'm seeking to update it with a clever thermostat, a nest. Can i use the nest as a substitute?.

If you have enough wires inside the thermostat cable among the eim and the thermostat area, it's feasible you may take away the eim and simply use the ecobee4. I'd want to recognize extra about your present heating/cooling gadget along with warmth pump or no, multistage heating/cooling and in that case, what number of degrees, twin gasoline furnace/warmness pump set up, etc... And also how many wires you have got in the thermostat cable to tell you if it's feasible to make the conversion.

Now not as a communicating stat. Your stat is the excessive end stat for "speakme" to and fro with the furnace to run as efficaciously as viable. If we use the nest we lose that and we must rewire the thermostat twine to where 5 wires at both ends, using lettered terminals in preference to numbers.

Ok, thanks for that data. So the ecobee4 received't be well matched with the eim, the present thermostat is simply receiving strength from the eim and the manipulate of the machine between the eim and the thermostat is completed wirelessly through a honeywell proprietary wi-fi protocol.

I see what has took place. The present thermostat is ready for "speaking" with the furnace and does not use the usual 24v sign like every different thermostats. The one you presently have is designed especially for special excessive furnaces. It makes use of 3 "records" wires to speak. Would need rewire at furnace and at thermostat to new terminals at both ends and make a non communicating thermostat. Which by means of the way does decrease the efficiency.

I've a honeywell th9421c1004 thermostat that i'm changing. When i get rid of it from the wall, there are 3 wires that go into the bottom however they're no longer marked. I have principal warmth, vital air, and a humidifier. How do i become aware of every cord?.
