What is the dampner for. During the winter, when I want humidity, what position should the dampne...

Asked by Jeff January 28, 2019
8
Answers

The damper controls whether air circulates through the humidifier. So it should be open (lever horizontal) when you want humidity, and off (lever vertical) when you do not. When you want the humidifier running: 1) Enable humidity control on your thermostat, and ensure that the humidistat (connected to the humidifier) is turned up sufficiently. 2) Turn on water to the solenoid valve (if it was turned off during a previous deactivation) 3) Turn the damper on, so the lever points horizontally. Once you turn everything back on, visually inspect the light on the solenoid control valve and make sure it is activating periodically, and that a small trickle of water is flowing through the discharge tube. Some thermostats activate the humidifier only when the heat is running, and others allow enabling the fan and humidifier even when the heat is off. Check which yours does, and only check the solenoid lights and for water flowing when the humidifier is active. Disabling it during more humid months is the opposite of the 3 steps above.

This sounds similar to my problem, and I think the solution is simple, and speaks to bad label design. The controller label shows the three settings (high temp, low temp and no temp) controlled by the two little switches next to it. It isn't clear if the black square or the white rectangle in the switch illustration corresponds to the top of the switch slider, or the bottom. In other words, try reversing what you think the positions should be for "high temp", pushing both switches up instead of both down. When I did this, it worked: When the furnace is forcing hot air, the blue light now comes on for 2 seconds, before a 30 minute pause and the water flows into the humidifier.

Can this unit be controlled using a digital humidistat or a NEST therostat?

Asked by Mp74 February 2, 2018

Answers

The humidistat that is included in the kit for the 12HF is wired in series in a 24V circuit. As long as the device is able to be wired in that same way, it should work to control the whole house humidifier.

Asked by StillLearning February 3, 2018

Answers

No, you cannot. The heat generated on the supply side could damage the humidistat, and reason you want to place the humidistat on the cold air return side is that it is sampling the air from the living space to determine if the humidity level has reached the set point.

You really need to call us at 800-879-0123 so we can verify some key steps of your installation have been done properly. For now, shut the water supply off at the saddle valve, and unplug the transformer to make sure the unit is OFF. Hope to hear from you soon.

Can this be installed on a PAC unit HVAC?

Asked by Barron December 30, 2017

Answers

This humidifier is not a good fit for this specific type of application, meaning weatherized outdoor package units. While we do not offer a steam type of humidifier, this may be a better choice for your application.

is drain required for this unit?

Asked by Baga April 24, 2017

Answers

Yes. Water is released in short bursts at the top of the unit and trickles down through the pad. Excess water runs out the bottom through a hose to a floor drain or equivalent.

Does this come with a warranty?

Asked by Eddie December 25, 2020

Answers

One year on parts, lifetime on housing. Parts are expensive and I found to replace parts out of warranty it was a better cost benefit ratio to buy a whole new unit. I had about ten years on my first unit.

The efficiency will go down a little but it will still work.

This humidifier consistently maintains 40-42% humidity on a gas furnace, with outside temps about 40 degrees. Install was not hard even with cutting into the ductwork. The 2 screws for the diffuser were the wrong size (#8 vs. #6) but had some on hand. The wire from the controller to the valve needs to be longer. It's only long enough if your supply and return access is on the same side of the furnace. Last, I would recommend a stiffer 6" flex duct. The 3' piece that was included wasn't long enough for mine, and the one I bought was sturdy enough not to need any added support or clamps. Overall I'm happy with the 12HF humidifier. I dropped the thermostat 2 degrees since it actually feels warmer in the house and the nose/sinuses feel better.

Inadequate for desired humidity

Product was received as advertised and installed per directions with no issues. I am going on my second season of use however I have been unable to achieve a desireable humidity level of 39-40%. I have a 1600 sq ft home and with outdoor temperature in the upper teens to mid 20's the indoor humidity level will not exceed 33%. I believe this unit is helping with humidity but the unit capacity is over rated and did not meet my expectations.

Took a while to install plus a couple hours troubleshooting... make sure your water pressure is not too high as the relay can't open the valve, the directions say psi over 90 is too much I think it's a lower threshold, I switched to the saddle valve and it seemed to work better. All in all it seems to be working well, humidity is definitely up in the house.

Replaced a 20 year old foam roller unit. This thing really does the job. Easy to install. I really like the water saving feature. You can hear the valve cycle on and off due to the provided timer relay (make sure to install it as shown between the valve and ac voltage supply). Note: use the 24vac from your furnace. The provided 24vac plug in supply has too few amps to properly energize the valve at times without buzzing, which is valve solenoid chatter. Finding a larger 24vac transformer is easy if your furnace cannot supply it.

Performs exactly as advertised, very quiet and does a great job moisturizing the air in my little 672 sq. ft. home. No significant increase in my water usage either.

Works Great but the installation may need enhancements

This humidifier would be rated 5 stars for an application that requires no adjustments to the supplied installation plans. My basic, forced air furnace is installed so that only one side of each vertical plenum is accessible. It was necessary to install the humidifier on the wide side of the hot air plenum and then use rigid 6” round duct work to feed the unit’s output into the horizontal cold air plenum. This unit is designed to fit the flexible duct that comes with it. The output port of the unit is much smaller than the female side of a 6” round duct so an adapter had to be fabricated. By hammering out the crimps of the male side of a 6” elbow, it then fit nice and snug onto the supplied plastic starter collar. During testing, the pulse module never came on in the normal setting. The “LO” setting worked but would continue to pulse water for 15 minutes after the furnace turned off. An outlet was installed on the side of the furnace for the unit’s AC adapter. This outlet was wired to toggle on and off with the furnace fan. I was then able to leave the pulse module setting on low with the unit automatically shutting down when the furnace fan turned off. The unit works perfectly now, but I feel installation enhancements such as this would be beyond the ability of many home owners. The media pads are not carried at Home Depot and must be ordered on-line. One pad should last an entire heating season. In summary, this type of humidifier, with a flow through water system, is the only kind to use. I’ve had plenty of bad experiences with the rotating drum, water bath, calcium clogged nightmare types to never go back.

This is a great product. I read the reviews online and discovered the Honeywell model has issues, so I went with Hamilton. Very pleased and zero regrets. I have a 1,600 sq. ft. house and this unit can make the windows drip with condensation (I actually have to turn it down). No moving parts (except the water solenoid), no slimy drum to clean out, and best of all no humidifiers to refill. See the pictures, attached. The directions say it can be mounted to either the return or supply ducts at the furnace. I have a flex duct return, so I wanted the main body of the humidifier mounted to the solid surface of the supply duct. The directions did not describe this scenario, so I improvised. I hope the attached pictures and drawings help someone else in the same boat I was. I did have to install a 110VAC outlet for the power. However, I already had an existing drain (for AC condensation), for the drain tube. The unit works beautifully and no more dry skin. Great job Hamilton!!!
