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

Need a humidistat for the &lt;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 Controller Really nice, but expensive.

Hi Bob. I bought two fans. This one from Home Depot and another one Air King BFQ 50 CFm from Amazon. Both are running really nice. But they dont have a delay timer or humidity sensor. They both shutdown and turn on by flipping the switch, but to compensate it I bought two Dew Stop, Humidity Sensing Fan Switches Model: FS-100-W2 from home depot. This switch has delay timer for 30 min and humidity sensor. He completely control humid in my both bathrooms. Good thing about those fans they are real quite that my kids can not notice with close door than they are running.

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!

sometimes if you unplug it and then plug it back in it reverts back to a default humidity setting. check to see if the setting is below 65%. i intentionally put mine on 45% and just let it run. when it reaches 45% it still runs but the dehumidifier part is on standby until the level goes above 45%.

No, the fan does not run all the time. Once you have set your humidity level the unit will only activate to maintain the the desired level.

The humidity sensor is not on unless you turn it on. If you have a timer turn it on, the sensor will not be working.

As long as you install the power switch to fan where you can get to it that's easy to do. Turning the fan off and back on immediately starts the fan in high speed. Turn off switch for about 10 seconds to put back in humidity control mode. Light turns yellow for full speed and turns blue when properly reset.

I was in the basement when the fan did shut off. It started back up a little while later. So Yes, when it reaches the desired humidity level the unit does go silent and then start up when it needs. The unit is in the basement but it is no louder than a small fan running. There is no noise when the water drains from the unit.

Note that turning on the A/C to control humidity will not work. It will only lower the temperature in the area and can actually increase the RH in that area. If you are controlling a dehumidifier that is different, as it first super cools then reheats the air to the desired temperature to deliver the required humidity and temperature. If you really want to connect the humidistat up the answer depends on what type of thermostat you want to connect to? If it is an older Heat/Off/Cool type there is no easy way as the connections you need are across the cool side of the selector switch to the yellow wire which is the cooling control wire (typically yellow but color can vary). Since the cool side of the switch is internal to the AC thermostat it requires some soldering to modify, it can be done but since you are asking the question I assume this is not something you would be comfortable doing. If you connect across the Red and Yellow you are bypassing the switch and possibly the fan control. Thus the A/C may run but the fan may not.

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.

wait...think it might shut off fan if you hit the humidity level u request...could set it low enuf and i guess it would never reach shutoff

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.

It will restart, but at the factory default settings: Humidity Setting at 60% and Fan Speed on low.

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.

Hmmm. Just make sure you have humidity level at 50 or 55, fan on auto. Open windows? A no no. If all that doesn't work, sounds defective.

Hi Gary: Don't know what a humidity on setting is.... this is an exhaust fan, when turned on it runs and when turned off it doesn't. We are very happy with it, since it is extremely quiet and does the same job as the noisy fan we previously had.

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
