I currently have the 760. It fell off the furnace and cracked. Will I have to rewire everything?Or can I use the old wiring, waterline and humidistat?

I replaced an older Aprilaire with the 700M and had no problems using the existing wiring and water supply.

I replace a 700 manual with a 700 manual so I didn't have to worry about compatibility with wiring and water supply. I am not familiar with the 760.

I assume you are replacing the cracked unit with a new one that is identical in revision. If so, there should be no reason you cannot use existing wiring and control. I would replace the waterline, though.

inspect wiring for damage,make sure it didnt pull wire off of humidistat,and if water line isnt kinked or broken it should be okay

Sorry I missed that it was not installed. You may not need one unless you have a humidifier or electrostatic filter. In which case there should be wires coming from either side at the lower half of the furnace trace those to perhaps a shut off switch. Thoses wires will tie into the transformer and a power source. If you cannot find the wires coming out you need to have the contractor finish the job.

Yes, but with a few changes. The main unit is the same size but the humidistat/controller is smaller. The transformer is now separate (not built in) so you need to do a little extra wiring.

Hi Chris,This is the one our electrician said we could replace our 80's model with.Due to remodeling, we have not installed it yet. We sure hope it works!Sorry I could not have been more helpful.

Yes it will with minor rewiring. Take one wire common from furnace straight to solenoid. Other furn wire to humidistat. Second solenoid wire to stat. And it should work fine. Think of the stat as nothi g more than a light switch. Hope that helps.

I think you might need the next model up (with a W2 terminal) for your system: TH6220D: For up to 2 Heat/2 Cool systems

You have to use new one. I had to take panel off wall and fish wires all over again.

No, the fan motor is 120VAC and the humidifier controller and water valve are 24VAC. You will damage them. Without knowing exactly what you have it is hard to tell you how to hook this up. The 500 control box has terminals that will match your home thermostat terminals and your furnace terminals. Terminal R-is red wire, Terminal W is a white wire. Terminal G is a green wire. And terminal Y is a yellow wire. Match the terminals from your thermostat or furnace with your Aprilaire controller. the wire can be purchased on line or from your local building supply like Home Depot. Both the Aprilaire humidifier and the controller come with wiring instructions. However if you have a late model high efficiency furnace it will have a humidity terminal marked HUM. If this is the case connect the Aprilaire controller G terminal to the humidity terminal. No other wires should be on the Aprilaire controller G terminal or the HUM terminal of the furnace. If you connect it incorrectly you do run the risk of damaging the controller, your furnace or both. I have 30 years experience in control circuits that helped me hook this up. Better to ask a professional for help if you have any confusion. Followup after I looked at my furnace connections. I made one mistake for the HUM terminal on high efficiency furnaces. You need to connect W terminal of humidity controller to HUM of furnace not G. FYI on furnace connections R is power out to thermostat and controller Y is demand for cooling input to furnace W is demand for heat input to furnace G is run fan with no demand or heat or cooling input to furnace C is return for power and is required for humidity controller to provide power return path. It is also used on high end thermostats that require power. Normal thermostat wire is 4 conductor for newer thermostats you may need the C connection. Home Depot has 5 conductor wire.

My understanding is, it can replace your Lennox X6675. The only difference is MERV number. This one is MERV 12, it might be different from Lennox X6675. I feel MERV is good enough for my house, but it might be up to person from person. So no problem to replace it, depending whether you can accept MERV12. Hope it is helpful.

No Eric - you need to but a plug in thermostat be careful of your electrical system - I burned out the circuit using this heater and had to re wire that room and put it on it's own breaker - my house is 100 yrs old and still had some hidden nob & tube wiring which I feel contributed to the problem - ever since the new wire is in no problems

Hi Patrick no, the unit is more for replacement i used my existing wiring and air tube. hope this helps ?

Assuming that you are replacing an existing thermostat, replace the wires in the exact same sequence as the old. I always make wires before I remove them. If it is a new installation refer to the furnace wiring instructions. If you are a novice electrician, call a professional installer. It costs money ,but you will get heat and cooling that works.

I replaced my unit last summer. The new unit had every part you will need but you will need to buy some plumbers tape to out on thread when reconnecting lines.

Yes, even if the connectors dont match up- just cut the connectors off of both ends (the new part and the one coming off your unit), splice the ends, then wire nut them together. This is basically just a ceramic resistor that heats up (red hot) when an electrical current is passed through it- thus lighting the gas inside your furnace. Kudos to you for doing this yourself! You just saved yourself alot of money =)

Pretty simple...just have to remove old unit and reattach new one, connecting the proper wires to one another...lots of instruction/how-to videos available on YouTube. It's not hard as each wire has a certain color, etc.

Hi Sheldon, It was very easy to replace. The directions are clear and easy to follow. Just determine what type of system you, look at the directions and follow. The terminals an the new thermostat are labeled for wire color. There is one "jumper" on the new thermostat that you may or may not need depending on the system you have. I did not need the jumper, so I removed it ... easy peasy.

NO I agree with Fred buy the complete unit. In my case mine was old enough that they were not the same. Just write the color coded wire order before you remove them. Very easy to change.
