I installed a Honeywell 360 Whole Home humidifier on my Carrier infinity 80 unit. The humidifier starts and stops by sensing air flow. Everything works great in standard operation however the Carrier has a variable speed fan and it appears to be more efficient to run the fan continuously...hence the humidifier runs continuously and it uses a ton of water. Is there a way to wire the humidifier so it only comes on with heat or AC? I have a White Rodgers 1F95-1277 stat and the humidistat is located at the return plenum.
As long as the humidifier start/stop is regulated by air flow there is no way to cycle it on/off with another device. If, however you disconnect that capability and, instead wire it to the heat on cool on switch it will only turn on when the stat calls for heating or cooling. You may need to install an intermediate relay off the stat wires to regulate the different(assuming that they are) voltage of the humidifier start/stop.What a fun project, thanks!
Thanks! Good suggestion! Zero experience with intermediate relays but a good chance to learn.
Would you know why the humidistat is satisfying at 10% when another shows 40% humidity in the house? Unit is in attic and humidistat is cut into and attached to return plenum. It acts like its reading the attic humidity instead of the return air? If I could get the humidistat to read the actual humidity in the house I would think the humidifier would just turn off when satisfied at 35% setting?
It probably is, especially if the duct leaks around it or the real sensor tip is in the attic. Humidity meters are notorious for being way off callibration.

If you used the plastic tubing to the humidifier(I recomend copper) there should have been a little brass tube with a flare on it. This goes in the plastic tubing to grip the the sleeve better. See if this helps

The humidifier is designed to "pull" the air through the water panel. After it does the humidified air will re-enter the plenum on the side of the opening that it is pulling in from. Just keep the water panel replaced every year and you will be fine.

Neither, even if the solenoid or humidistat stick, it should always drain properly. Is the unit mounted on the cold air return duct or the supply plenum? If it's mounted on the supply plenum, the water panel might be getting blown forward and spilling the water. High efficient furnaces also can leak water on the floor if its drain is restricted. If hum. is mounted on return duct make sure drain is clear by blowing through it. On Honeywell hum's I've seen the rubber hose from the solenoid valve to the distributor tray leak too, check the rubber 1/4" hose.

hi the water runs down the pad the fan blows air across is , this controled by the stat which should control the water flow / on or off, this should be under warranty in the first year

I'm not an hvac guy, but I'll throw this in...is it possible that the relay contacts are welded closed, even though the relay has open coils? With all the power off, try to see if that's the case, and change it, but check everything ahead of the relay to make sure there's no short drawing excessive current.
Hope this helps.
