New humidifier install


I'm cornfused now- I thought I was using the R terminal for power?

I'd like to put the humidistat upstairs on the main floor rather than in the basement, so can I just run a shielded 6 conductor wire from there down?

Thanks for the fast reply!

Someone feel free to slap a picture up!

The r terminal is constant 24v supply for thermostat,the h terminal should have power to it only when thermostat is calling for heat

If you put the humidistat in a room, it will only be sensing that room, if you mount it on the return it senses a mixture of air from all over the house, thats why we call it a whole house humidifier. as far as power to the humidistat, the easiest way i can explain it is as follows.....start at hum go from there in series to the humidistat then to the solenoid and back to C on the low voltage strip.

plummen- thanks for the clarification on that, I think I have it now. Need to go pick up some wire at the hardware store so I can continue wiring. One thing about moving- I have no idea where some of my stuff is yet... :D

harleyrider- ok, I never though of it that way... It'll be going on the return. Thanks hr- wouldn't be attempting this without your help!

New humidifier install


I am trying to figure out what rate of water flow I am supposed to have when the blower/furnace is on. When I first did the install, it was a steady drip, and I recall reading somewhere that "drip" was what I would see, so I didn't think much of it. On Monday, I noticed that the humidity in the house was dropping rapidly, and when I checked the humidifier, the solenoid was opening but no water was flowing. I traced the lack of flow back to the saddle valve, and when I took that off, no water was flowing from pipe at all, so I assumed something was clogged in there. I took the point of the saddle valve needle and pushed it in and wiggled it around a little whacked it gently twice with a wrench. When I removed it, there was a very fine stream of water flowing out of the waterline. So, I reassembled the saddle valve and water line connections to the humidifier. The water was getting to the humidifier again, but this time, it was coming out of the supply line that goes to the evaporator panel in a steady flow (versus the fast drip like it was before). I also noticed water was also actually discharging from the drain hole at the bottom of the unit at a fairly steady rate, where previously, I was only getting a very small amount of drainage to the condensate pump and only after the system had run for awhile.

So, what rate of flow is correct (fast drip or stream)? If I am getting too much water in there now, how do I slow down the flow, since my understanding of saddle valves is that they should only be "on" or "off" and not used to control flow rate?

Joe Dirt--congrats on getting the system installed. I also thought about the upstairs humidity controller but opted for putting it on the return for all the reasons everyone indicated to you. However, I did got out and buy fairly relative humidity "meters" that also read outdoor temperature for each of the floors of our house so I could get an idea of how the numbers on the main humidifier control/sensor compared to the numbers I was seeing throughout the house. So far, my readings on the three floors of our house have been relatively consistent with each other, but they are about 5% higher than what is being displayed at the humidifier control. My assumption is that it's just a calibration issue, so instead of focusing on a particular number, I instead focused on the amount of condensation build-up on the windows. After a week or so of tinkering, I finally ended up setting the control on #4, and when it's 30 degrees, it reads about 35% at the furnace and about 40% on the three independent measuring points and I get very little condensation and only on the storm windows. Also, all the meters same to rise in relative unison with each other as the outside temperature increases. I'm not really sure what any of that means (or what the actual humidity level in our house is), but thought it might be helpful to you in trying to get things set to your particular house's conditions.

Thanks!

I have a pretty steady flow from my drain, not like rushing, but between a "heavy drip" and a "slow run" kind of thing.

I have to get a psychrometer or something to measure my RH, as the control is on 7, but the other half likes it so cold in the house (62-64) that the furnace doesn't run enough in my opinion to pump the humidity up. I am however hooked up to a cold water line right now (existing saddle valve to try it first) and maybe that matters a lot. I also do not have it set to run with a fan, and I do not yet have the external temp sensor mounted/attached so I am in manual mode for right now.

My control says between 33-35% right now, I let it run up to 70*F and was at 35%. How can I get it bumped higher if the upstairs is at 35% also? I have no condensation...
