(2 units in series) Underhouse Humidity>60% : turn on; AND outside H<50% : turn on the fan. Does this unit have connections for both?

The unit is a simple switch. You set the humidity at the desired level, and the switch CLOSES when it reaches that level. Your outside H<50% won't turn on the fan, it will turn off the fan. But you could have the outside H<50% control a relay to do this I think.

Need a humidistat for the <50% outside part. Found these on Amazon:IMAGE® 110V Digital Air Humidity Control Controller WH8040 Range 1%~99% RH HM-40 Type It requires 120 vac power Household power, and its contacts can only handle 5 amps at 120 vac.If your 120 vac fan draws less than 5 amps, you could use this.or,C.A.P. HUM1 - Humidity ControllerReally nice, but expensive.

There is only one sensor and it is inside the unit. I don't think this is meant to be outside, it mounts on the wall in the drywall. Whatever is wired to it will turn on when the set humidity is high enough and off when the humidity level drops to the set humidity.

on most package units or split systems you need to install a relay to bring the fan on with the AC most cases humid stat will only bring on the compressor. this will damage the compressor if fan is not running

If you want to have both conditions met before the fan kicks on then yes you can simply wire them in series. The unit is simply 2 wires with a switch closure in the middle that completes the circuit once it turns on due to high humidity. If you wanted either condition to turn on the fan then you would need to parallel them. I hope that helps. Mike

It has 6 fan settings actually. Low med high constant or auto where it'll shut off when it reaches the desired humidity level

The unit automatically shuts off when it reaches the desired humidity level - turn the right knob clockwise for more humidity. If this does not work remove and replace the front half of the unit - the electrical connections are sometimes finicky. If this does not work - does your unit need to be cleaned?

Both. On/off and heat dial from 1-30. Doesn't indicate the degrees, though.

They will switch on together. But you can put the switch outside the fan housing and connect it only to the fan. It is a sealed box with wires sticking out, so you can interrupt one of the connections to the fan and put the humidistat in between. BTW, I use 55% in th ewinter and 85% in the summer on LI/NY.

The humidify auto on/off doesn't work. Might just be my unit. I like the unit because it is quiet and has 2 speeds. It was suppose to be 35% humidity on this unit.

Yes, the unit has an on/off switch. It does not have thermostatic control. Nice air flow

I have (2) of these king air timers. They are much better than humidity sensors, as humidity varies so much in new england.I have (1) wired for both: fan & lights on/off together. ie 1 gang box needed.I have the other (1) wired for fan only. ie 2 gang box needed.:)

Yes it can. I've paired mines with the moisture switch. I haven't got the bathroom to a high humidity yet to have it automatically turn on, but I've tested it and it works as promised.

Easy...when installing, make sure the unit is attached to an on/off wall switch. The LED color tells you what mode it's in. When in HI mode(LED is amber)fan will stay on HI indefinitely. A quick off and then on again puts it into AUTO mode(LED is blue)which activates the moisture sensor and either HI or LOW fan. The unit will then turn itself on or off(adjusting the fan speed)according to the water moisture level in the room. Toggling on/off quickly changes the modes...simple!

The Sensitivity adjustment can be adjusted to low, medium or high. This will determine at what level of humidity the fan will automatically turn on. For example, when set to "high" the sensor is highly sensitive to the change in ambient air and will activate the fan at the earliest signs of humidity. On the "low" setting, it will take a higher level of humidity in the air for the sensor to respond and activate the fan. So you will turn sensitivity to high.

I own one of these. It works great! I live in southern Louisiana, and it keeps all the tools in my shed dry. Yes... the fan turns off when the compressor turns off... unlike some of the latest window air conditioner units. The fan runs only when the thermostat "kicks" the compressor on. After the proper humidity percent that you have chosen is reached, the entire unit is quiet... with only the pilot light showing on the on/off switch. I hope this helps you. I highly recommend this unit. RF, Cut Off, LA

If you leave the switch on "on" it is ready to respond whenever a preset humidity level is reached. Switch to "off" momentarily and back to "on" and it will run for a preset amount of time and automatically shut off. But, since the switch is still in the "on" position, it has reverted to humidity sensing mode and will automatically respond, once again. I have put 5 of these fans in rental units and I couldn't be happier with them. Be sure to check the screen over the sensing unit (where the LED light is) and remove dust so it will stay efficient.

It has a high and low fan setting. I run mine on the low setting and 50% humidity setting. It does not run constantly. What I do notice is a much dryer, more comfortable basement.

It turns on by a thermostat that you set. When the warm air hits the unit the fans kick on.

I hardwired the wall switch to be "ON" all of the time. The only problem is that the humidity sensor sometimes starts the fan in response to changes in the room air even when the shower is not in use. Darn kids!

No, just HVAC. This unit not designed to control humidity. Hope this helps!
