Taking the "G" off the furnace terminal and wiring it to the humidistat, is this the blower activation?

Yes. The G from the theromstat goes to the G on the humidistat and the Gf on the humidistat goes to the G on furnace.

It should. Just hook it to your forced air system and have it come on when the blower is running. I think they also sell a blower system so you can use it if you don't have forced air.

You have to be more specific... but anyway, here are my two cents: I suspect that the blower or the wiring to the motor is bad, because the motor should operate when the manual mode is selected (FAN). Check for voltage a the fan when the FAN is selected, if there is voltage at the terminal, the blower is bad, if not, check for an open to the wires. Also you can jump terminal R & G at the terminal strip, that should turn the fan on. Good luck

Nor sure how much current to activate but I set mine up to operate heater on a van so that power was not routed through fuse block and stopped the overheating. That circuit is 12v to run the blower motor, but I don't think it needs that much because it really snaps the relay when I turn on the key.

This humidistat runs off 24V AC and often has it's own step down power supply when the blower board doesn't support it. Check if you are getting 24V AC coming up to the humidistat. The solenoid for the water should be closed unless the blower motor comes on. The transformer is hooked directly at the blower board for aux power 115V. Check your manual for the diagram. If it's blowing the breaker, the blower board is probably detecting a problem with the step down transformer 115 to 24 AC. I'd be checking there. The humidistat acts like a light switch and that's just a simple circuit, open or closed. When you turn the knob you can hear it click, that's opening and closing the circuit to directly to the water solenoid. If the solenoid is stuck open, the solenoid is probably blown. The people who installed ours (before we bought the house) hooked it up without the 24V AC step down. 115V directly to the solenoid and poof it's gonna blow. When it blows, its stuck open leaving water constantly flowing. Here are two links to products that are comparable to what I referenced. Hope that helps.

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.

It's for the fan. I simply unplugged the fan and routed it to a separate fan controller that was powered by my main psu

Actually it controls the furnace, not A/C. But other than that, did you get any solid lights? Mine gave no lights, solid or blinking, and I had 24v.In my case, it was one of the relays that wasn't transferring the 24v to the blower.

The quick answer is: YES. There is a small switch inside the humidistat that changes it to manual. The instructions made it easy to change over to manual. It also comes with a decal that you put behind the knob to change the way the knob functions. I added the outside temp sensor. Took a few hours to run the wire, but now the automatic mode means I do not have to worry about adjusting the control when the temperature changes, and I can keep excess moisture from forming inside my window. I am very pleased with both the humidistat and the Aprilaire 400 humidifier. Tom

Ground!Be sure that your unit doesn't have a low voltage circuit that's available. Perhaps you'll have to run additional wire to the thermostat from the unit, but the extra unit may not be necessary, I was happily using it as directed until discovering that voltage was already on my furnace.Pays to check.Dee

I'm assuming that the blower is not coming on both before and after you replaced the control board. Ensure the jumpers are in the correct configuration and there is power to the board. Test the motor by directly connecting it to 120VAC. If the motor works, the board is installed correctly and it has power then the next thing to check would be the plenum temperature sensor. That is the "enable" for the motor. Does the gas burner come on for a while and then shut off?

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.

Yes, and very well. Need to make sure your humidifier/ furnace have the right control module to connect to this thermostat.

yes. you only want humidifier on when fan is funning. you will need a 12 v transformer.

Although it seems complicated it's pretty simple. The humidistat senses the humidity and acts like a switch. It will turn on a blower motor and or a solenoid on the humidifier. With an outdoor air sensor it will process the information and keep the humidity at a set level in the house. It will also work without an outdoor air sensor but it will not be quite as automatic.

From the interface to the thermostat, yes. If you have an existing thermostat with four wires, you should be fine. It can even act as your central humidistat with only four wires. Having the interface box probably simplifies things in many cases--especially in complex systems. I recommend drawing a simple schematic of your installation before you begin. I called Ecobee's support before buying. They were helpful.

A relay is included but I didnt need it. Check your furnace set up...chances are you have a 24v HUM hookup on your furnace.
