I installed a Honeywell HE360A about a month ago and am not satisfied with its performance. My home is about 2000 sq ft, built about 50 yrs ago, but all windows have been replaced and insulation has been added.
On a typical Winter's day, when the outdoor temperature is between, say, 0 and 30, I can only get my humidity in the house up to about 40 to 42%. The humidistat is cranked up, and I have verified that the unit turns on everytime the furnace turns on, and that water is running through the pad.
I read another forum saying that its better to install on the return air side, but that is not possible for me--there is not enough room. My furnace is downflow--the furnace and return air duct are on the main floor, and the warm air plenum is in the crawl space (which is where I have the unit installed). Also, I didn't want to run a duct through the floor--that is why I chose the power humidifier.
I spoke to Honeywell customer service, and they were not very helpful. They said the unit is working properly, but the load conditions prohibit attaining higher humidities.
2 questions:
1. How much would using hot water help? (I am currently connected to cold.)
2. Also, what if I bypassed the furnace relay to allow the humidifier to run even when the furnace is off? Would this increase my humidity?
Thanks for your help.

That setpoint is plenty high, You don't want it any higher than that. if you go high on a cold day, you are asking for trouble in hidden spots, and wet windows.
Here suggested settings.
Outdoor Temperature------- Recommended Setting
-20ºF--------- 15%RH--------- (Low)
-10ºF--------- 20%RH--------- (Low)
0ºF------------ 25%RH-------- (Medium)
+10ºF--------- 30%RH-------- (Medium)
+20ºF--------- 35%RH-------- (High)
Above 20ºF---- 40%RH------- (High)
I read another forum saying that its better to install on the return air side,
You don't want this model on the return... This is a powered unit, and needs hot air to run. By-pass system can go on return since hot air is going over the pad.

It may help keep up a bit better, not sure what the % is. I have mine on hot water.
2. Also, what if I bypassed the furnace relay to allow the humidifier to run even when the furnace is off? Would this increase my humidity?
Last year, I program my t-stat to force can on when need of humidity, and it seems like I wasted more water, now I changed the t-stat to only run the humidifier on call of heat, and keeps up just fine.
