Does anyone know if I have aprilaire humidifier, this can just get connected to 1 wire to solenoid and another wire to transformer ?

This humidistat is a mechanical switch. It's non-powered. So whatever you put it in series with it will turn on and shut off depending on the setting and ambient humidity. As humidity rises above the setpoint, at some point above the deadband the switch will open. When humidity falls below the setpoint, at some point the switch will close. The deadband is 5% of the ambient humidity. I have mine connected to an 120VAC circuit and it works fine. I do not know how many amps it can handle but the connections are 18AWG solid which can handle 14amps. I would not try to load it that high...maybe 10 amps tops. If you are wiring it in series with a solenoid it should be fine because solenoid current is usually in the milliamp range. So the answer is yes if the solenoid you are connecting it to turns on the humidifier. The wiring is also rated to 300VAC so provided you are using voltage under that you should also be fine.

There's a transformer box this uses, and the wires it uses look to be about 16 gauge. I have to assume pretty minor. Like the previous guy said, it's just turning on a water solenoid and turning it off, the house water pressure and the bypass of your furnace do the rest of the work.

If you use the schematic listed for "Automatic" operation (i.e. intercept the "G" wire between the thermostat and the furnace, putting the new humidistat in between) then this unit will be able to use the furnace blower without firing the furnace. Tapping into the hot water supply (instead of cold) is recommended if you use this feature. My 700 is installed this way and works very well in this configuration.

Sorry, I have no idea. The humidifier only lasted 2 years before it died. Very disappointed considering the price I paid.

Yes . It will keepYour coil in new condition . I do have a April air filter and humidifier on my own system

Sorry but is will not control a humidifier. It will heating (gas, oil or electric), cooling (multi stage), even a water heater, and can display inside / outside temperatures.

Don't know.-- Added my own meter lights and replaced an internally shorted transformer with a bigger and better one out of the junk box. Also put higher capacity pass transistors on my second unit. Yeah the fan gets growly; other than that they both work.

I got it for my Swiss humidifier. Not sure. I descale once per month in the winter months when I use it.

The humidistat requires 24VAC. I bought the transformer from Amazon (Elk TRG2440 24VAC, 40 VA AC Transformer). I use my humidistat to drive a stand-alone dehumidifier and it works great.

You might need 2 of these but what's the reason you want to use this when you have to charge it for 8 to 12 hours and then unplug it and use it until its power wears of an plug it again. It might be useful if you are one that goes out of town and the humidifier working. I use it for my car when I go out of town. Have you checked the Eva-air Petite Electric Dehumidifier? If might be better for bedroom, again depending on your purpose. I have one of the electric. So it is continuous and trips off when the water it collects in its built-in container gets filled.

Not sure about buying the tank... but you could buy an identical humidifier and use its tank with your current base. Then whenever the current base fails to heat you could use that tank with the new base... Just a thought...

Search the WEB for Aprilaire 500 instructions and video. If you do not have a humidifier on the furnace there will be some work involved.

Sorry, but I haven't tried the humidifier yet. Heater capacity in a larger room is disappointing

This unit only has one set of relay contacts. You would need to run two of these units. One for Humidification and one for Dehumidification.

The instructions say you can just run a wire from the Aprilaire 800 to the (provided) humidistat. But, if you do this how will it know when the furnace fan is on? Will The A. 800 just and steam without fan running?(Please, note I don't want to buy or use etc pressure switch or (optional) fan pack.)

It can be used in a 120 volt circuit but not directly. Buy a doorbell transformer at Home Depot or Lowes and hook the humidistat to the low voltage transformer (12 or 14 volts: cannot remember exactly which it is).

it depends..... if you are replacing an existing humidifier, then it is not that difficult if you are a handy person and the new humidifier fits in the same space as the existing one. However, if it is a new installation, then you have to make the water (both intake and discharge) and electrical connections in addition to physically installing the humidifier on the furnace. That will require the skill of a technician if you are not too handy. I replaced my old squirrel type humidifier with this type and did not have any problems, but I am very handy in house repairs.
