Aprilaire 560 not keeping contant power to cause humid. to work
I have now replaced ALL the parts on the humidifer (wiring, hum, solenoid, humidistat, current sensing relay). It still does not work properly. When the furnace comes on, the humidifer does not come on. I can wait until the blower comes on, turn the humidistat down and back up, it clicks and then stays on until the blower turns off. So all parts work properly, but the system does not turn on by itself without my turning it down and back up to get the click. It almost seems like the sensing relay sould be atached differently. I am at my end of my ability (not much there to begin with on electical parts). I hope someone else has had a similar issue. We are really dry in our house.
Re: Aprilaire 560 not keeping contant power to cause...
You may be havig problemm w/ the current sensing relay, try bupassing the current relay and see if the hum. comes on and if it comes on the try rapping the wite wire from the main blower 2 times. hope that helps

It sounds like it is just miswired. The low voltage wiring off the humidistat should be on W and C on the circ. board at the furnace. If you have it on R and C then it will power it constantly regardless if the heat is running or not. W is only energized on a call for heat which is typically when you want that type of humidifier to run
Hello, sounds likemyou have either a bad humidistat or solenoid valve, disconnect the wires from the humidistat if this turns off the humidifier than replace the humidistat. If not the solenid valve will need to be replaced,
Hello, make sure you are getting 24 volts at the transformer, if not turn off power to transformer and check resistance on the secondary side of transformer, you should have resistance if not replace transformer. If you have 24 volts at transformer than check the wiring and make sure it is tight. the last thing to check is to make sure you are getting 24 volts in and out of the humidistat. if you are not replace humidistat.
Follow manufacturer instalation instructions. Why risk your equipment and you family's health to save a few bucks and a lil trouble on the proper parts. Your family is worth it, now go do the right thing. :)
When humidistat is at ouside temperature that may be a lower humidity setting than is in your home. Doesn't sound like there is a problem. If it is too dry in home you can set it above ouside temp to turn on. The ouside temp setting is estimate that you will not get condensation on windows.
It sounds like the humidifier may be improperly wired.
It's hard to solve without checking the wiring, but it seems like the humidistat is wired so that as the dial is advanced, it incorrectly turns on the fan, or furnace, or both. The contacts of the humidistat should be wired so that they turn on the solenoid only. Also, the power to the humidistat, to turn on the solenoid, should come on only when the fan is on.
Hope this helps!
I just solved a problem with mine today. One of my low voltage power wires to the humidity control had a bad connection. I reconnected it and I could again hear the solenoid valve clicking as I adjusted the dial control.
I found the problem with a voltmeter: there was voltage at the power terminals on the humidity control terminal board, but there was no voltage at the solenoid valve terminals. It was hard to push my big wires into the terminal board, but I finally secured the connection!
Was having a similar problem. Disconnected the source line and opened saddle valve. I was getting water to the solenoid but nothing out the other side. My humidistat doesn't have a "test" setting, it's either off or the highest humidity. I held the outbound line in my hand and experimented with adjusting both sadlle valve and humidistat. I didn't get any water until I opened the saddle valve MUCH further than I thought was necessary and turned the humidistat to near the highest setting. Once I had water coming though I experimented with the setting on the humidistat, turning it off and then slowly increasing the humidity until the solenoid clunked and water started coming out. I would recommend anyone having this same problem to open the saddle valve all the way (I was surprised how many turns that took) and set the humiditstat to it's highest setting.
