My humidifier is only powered when the furnace blower is operating ie. no power to humidistat when furnace off. Does this humidistat take batteries?

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.

There are no provisions for batteries. However, since you will need to wire it to the humidifier, there are many power options. AC from the furnace power or even a separate transformer for the humidistat. Either way, it will need power all of the time even if the furnace is not running. Most often, the furnace wiring can provide that. Wiring options are in the manual which you can get online from Honeywell. It is a very nice unit.

No it doesn't take batteries. There are two circuits on the humidifier terminal board. The IAQ needs to be powered off the 24V circuit continuously. The other is the one that breaks with the airflow switch. It sounds like your 24V is being interrupted until the blower starts.

No batteries. Mine is the same, wired to transformer. Honeywell helpline is of little help to protect tradesmen.

P.S. You can power it off the R & C terminals where your thermostat ties into your furnace if your thermostat is 24V.

I too experienced the same thing with this Humidistat, it would switch open (off) when the humidity would fall below the set point and would switch closed (on) when the humidity went above the set point. I found this opposite on how I was expecting the device to function. Has anyone else experienced this?

There is no battery, and no USB. This humidifier runs only when attached with the wall wart transformer to the AC mains.

I'm not familiar with the wireless thermostat transmitters. The humidifier can be wired to operate through the fan circuit or the heating circuit. When the thermostat calls for heat the humidifier turns on and off with the heater, through a duct mounted humidity sensor powered by 24 volts. It can also operate if the fan is manually turned on at the thermostat and the fan is wired through the duct mounted humidity sensor. That being said, I guess if the transmitter (sensor) can be programmed to turn the fan on when it calls for humidity, it may work with heating and in manual operation. Hope this helps.

Not quite. The timer only has 20 on/off cycles per day Ex: On at 12 off at 12:10 On at 1 off at 1:10 On at 2 off at 2:10 This is 3 on/offs I use this for my snake cage.

It comes with a humidistat. I leave the furnace fan on all the time anyway but the humidistat is supposed to kick it on when it is on. I recommend installing it with 220 as it will make the unit more efficient. Other than that, I can't be happier. I live in Colorado and the humidity can drop under 20% in the winter. This unit keeps it above 45%.

Interesting. I would contact the vendor. My night light turns on briefly when you push the button lightly and turns off when you let go. It also turns on permanently when you push it more firmly. I never use these night lights though, so can't help you there. I do highly recommend this humidifier, though. I think if you return yours and get a functional one you will be happy. All the best.

The humidifier would run constantly if solonied valve was energized always , might get too much water in system , I wired into fan only gets water when fan is energized

No battery backup in mine. However if the power goes out, your furnace won't run it's fan anyway. When the power comes back on, the thermostat will resume as left off. We have ours in a vacation home and the power goes off intermittently throughout the winter. The thermostat is always reset and functioning when I check back in. I really enjoy this thermostat for checking in on the house and the external temperatures remotely, and for turning on the heat before we arrive in the winter.

See the comment by Gene. Note that if you have only two wires from boiler to thermostat you can't power it from the furnace so have to use battery.

A few things. If it's several years old and it's running all day, the motor could have burned out. After usage, was the humidifier cleaned including wiping the blades? Was it ever stored where there is dampness such as a basement? Several factors. I've had mine over 8 years and it's a table top. When it goes, I know I got my money's worth and will buy another unit. It is NOT worth it to replace the motor IF that is the problem as it's too costly. Good luck.

The manual doesn't say anything about the machine "turning off," it merely says "Red light indicates that water bottle needs to be refilled." But, Crane humidifier representatives say that their animal-shaped humidifiers turn "off" when they run out of water, even though the red light is still on. So, I think it's reasonable to expect that other manufacturers have likewise designed their humidifiers so the mechanism stops running when the water supply runs out. My Miso humidifier often stays empty-but-on for a while before I get around to turning it off and it's still operating fine. Once the red light switches on it's as quiet as as when it's all the way off. Just make sure you turn it off and empty it all the way out if you're not actively using it for a while.

The humidifier only runs when the furnace fan is running during the heating cycle. During the central air cooling cycle, the water supply to the humidifier needs to be shut off and bypass air damper closed as there is no need for humidification in this cycle. However the electrical connections were done by the contractor and am not aware of these details.

The right button if you hold it down should turn on humidifier. It will sound like a fan is kicking on and a mist will come out of top. The left is to turn on and off the lights. No I don't believe that it de-humidifies.

Air has to move thru the humidifier. This happens from the furnace blower. You can run the fan motor without heating or AC. For my application I purchased the relay shown as an option. Makes the install easier.

Don't know. You might check with the humidifier manufacture for restrictions, or if it would void the warranty or damage it.
