Yes,humidity does tend to increase when it gets warmer out.Winter causes humidity to go down and gets very low and would easily make a humidifier come on more.Even when winter temperatures do get higher,it does not always cause the humidity to go up.Winter air is quite dry no matter what temperature,unless a rain storm rolls through.I am also a little confused by your post but I think you are in winter now.Turn your humidifier level down slowly to make sure it does go off.Turning it up absolutely will make it run much more.In winter,humidity levels probably do not go much higher than 30%,as long as you are not in the South or near a large water supply.If it snows during winter where you are,the air is very dry.I could not find a downloadable user manual for your item.Is the scale set for 0-100,same as humidity level on the news?If it is,setting it a little lower than 40 should make it turn on alot less.When I used to live up North though,the first week or 2 of having house heat on would occasionally give me nosebleeds because the heater makes the air very dry also.If you have a problem like that,or even when you wake up and your nose and mouth are very dry,you may want to set it a little lower when you are awake,and turn it up a little more when you sleep.Researching yours I found a post on this site from a couple of years ago.
Your humidifier has it's own heater?Are there 2 different dials,1 for heater and 1 for humidifier?If there are,the humidifier would likely stay on even though the heat kicks off.If there is one dial for both,I'll have to check further.I would please like you to answer the questions for me to help.If I answered your question though,it's all good.I am listing the link I found.At least look at it and see if anything there has something which may help you also.Any problems or questuons,just comment here and I will get an autolink to your post and eply ASAP.Greg
