Aprilaire 700 running? Don't know.

[schenders]

New unit installed Tuesday.There is still no sign of it working.When you turn the knob to test,the green light flashes and you can hear the soleniod energize.This means it's working according to Aprilaire tech. It is getting water supply in and out of the solenoid.Loosened the compression fittings and inlet and outlet dripped ok but the media panel is bone dry,never been wet. The red led to indicate a mis wiring job is off and the fan,which is plugged into a separate powered outlet has never come on,even with the settings turned to maximum or on test setting. Also a good test if it is working is to see water coming out of the condensate drain which is bone dry also. All connections on humidistat look correct according to the installation manual. The humidity in the house reads a stedy 35%. I would feel better if only the powered fan came on. Thanks for any insight on this confusing matter. Steve.

Is the furnace running?

"It is getting water supply in and out of the solenoid.Loosened the compression fittings and inlet and outlet dripped ok but the media panel is bone dry,never been wet. "

There are three things not right here.

First, after water leaves the solenoid, it only goes through a short tube right to the top of the water panel. On the test setting, the solenoid should be energized and water should be coming out of the drain line. You say you here the solenoid energize, but no water shows up? Not sure on your particular model, but on my 760 there is a small filter screen on the inlet side of the solenoid and a small plastic restrictor with a hole in it to limit the water flow on the outlet side of the solenoid. Either of these could be plugged, though they shouldn't be in a new unit. If you investigate this, be aware that to take the filter screen out generally requires using an ice pick, which will destroy it. The flow restrictor can be removed and replaced without damage. Both these parts are only a couple bucks, are available online and are maintenance items you should have anyway.

Second problem is in the test position, the fan should also be running. What did Aprilaire tech support say about this? Did you verify power to the outlet? Verify that all connections are good, housing is closed correctly, etc?

Third problem is any tech that installed one of these and didn't see a problem with no water running out and the fan not on in the test position is incompetent.

I'd investigate some more and then call Aprilaire tech support again if necessary.

Yes I only do these tests when the furnace is calling for heat and running,blower on.

Trad I do agree.Thanks for all the help here. Contractor is coming back out Wed to install the outdoor temp probe that was not offered as an install option in the beginning.The main selling point of the unit. Thanks.
