SOURCE: electric heat strip installation and wiring

Need to make sure your wire size to the inside unit is large enough to handle the amperage, that you have a two stage heat thermostat.

SOURCE: Thermostat Wiring: W2? E? Where to connect?

You have a heat pump. You need a thermostat for "Heat pump with Electric back-up heat". Make sure the 'stat has either an "aux" (auxilliary heat) or an "E"(Emergency heat) terminal. The wiring instructions will be provided with the thermostat.

Hook up o to o/b, then in the installation programming set the change over valve to energize in cool. Then hook up w to aux. Good luck.

SOURCE: Wiring instructions for Thermostat Honeywell with Carrier Package

Jumper R to Rc and hook hot wire from transformer to R usually red wire
O = Reversing valve probably white or orange If you get heat when calling for cool or Vice Versa then switch wire from O to the B terminal.
Y = Contactor usually yellow
G = Blower usally green
Jumper Aux to E need to go to unit and use the wire that goes to your Auxiliary or 2nd stage heat
L = Light if you have this terminal on your unit then hook it up.
C = Common from transformer usually black, if you have this terminal on your unit hook this wire up.
Make sure you go to your unit and only hook these wires up if they go to these locations.

My simple comfort 2200 thermostat has a brown wire hooked to the e terminal. what is the e terminal for?


Likely for emergency heat. When the heat pump is in defrost mode, due to extremely low ambient temps, e is your indoor heat strips.

Simple comfort 2200 ~ what is the E terminal for? the brown wire is hooked to E terminal


E is for emergency heat which locks out the outdoor heat pump and brings on auxiliary heat when the t'stat is switched to "emergency" . This circuit will also be energized when the outdoor unit goes into defrost.

I am replacing an T8411R with RTHL3550 and I have the following wires. Original vs New G=G,R=R,Y=Y,O=O......? I have a W2 and an E wire that go into different screws on original but no seperate terminal...


C is actually a power wire; it provides power for some programmable thermostats. You don't have to connect it on the new thermostat; cover the end with electrical tape to avoid it causing a short. (If you keep that wire accessible, it will be nice for someone who wants to use another programmable thermostat. The ones which can talk to wireless networks require this wire.)

Do you have a heat pump? That is the only time a thermostat uses an E wire.

The W2 wire should go to AUX (third screw terminal from the left) and the E wire should go to E (second screw terminal from the left). See page 25 (27 on the pdf) of the Quick Installation manual for the RTHL3550. This manual is available from Honeywell at http://yourhome.honeywell.com/home/Products/Thermostats/Digital-Non-Programmable/RTHL3550D.htm .

I hope this helps.

I have an intermatic C8865 timer. i want to wire it into an EFM model AF150-1 coal stoker furnace, because the fire goes down to far inbetween actual times heat is called for. also have main switch for...


Intermatic C8865 timer is a 5-hour cycle timer that repeats same cycle each 5 hour period.
This timer has 120Volt clock motor and is 120V timer.
Timer has NO and NC terminals.
NO terminal turns ON when timer turns ON
NC terminals is ON all the time, except when timer turns ON. At this point NC terminal turns OFF.

You have 3 things: 120V timer, 120V honeywell transformer, 120V stoker motor/fan
The transformer needs to be ON at all times.
The stoker motor is going to turn ON when the cycle timer turns ON.

You have 120V cable with black wire, white wire (and bare ground, which connects to green ground screw and to other bare grounds and won't be discussed further)

Black wire is hot
White wire is neutral

Black wire connects to 'Switch common terminal' on timer.
Same wire also connects to black wire on Honeywell transformer.

White wire connects to 'Clock terminal' on timer
Same wire connects to white wire on Honeywell transformer and to white wire on Stoker motor.
So all the white wires are connected together.

Last wire is black wire to stoker motor.
This wire connects to NO terminals on timer.

Here is drawing.

Replacing WHITE-RODGERS manual thermostat with 3 wires ( red, white, blue and installing Honeywell electronic thermostat RTH110B, how do I connect it? The heating is not central, baseboard heating.


I have only seen one Honeywell thermostat that would work with a 3-wire heating system.

I would replace it with a White-Rodgers 1F80-0471. They are about $100, but they are a good thermostat, and they work well with the 3-wire zone valves.

Most other thermostats have the "Y" terminal that you need, but do not control the zone valve correctly.
