Honeywell HE100 and a Nest Gen2

I have hooked up my nest with my he100 and am not seeing any water flow. The HE100 has only 2 blue wires. So, I have the * wire connected to the HE100 The second wire connects at the C on board of the furnace and runs to the second wire on the humidifier. I get no water dripping down in the filter pad. Is there any good way to test that solenoid? I have good water flow when I disconnect the line and no air lock in the line.

 

Did it work with the old humidistat?

 

We first wired it up with the provided instructions and by we I mean my brother who is a plumber, we wired it in with the manual humidity controls according to the schematic provided in the manual.

When we would set the system to demand humidity the fan would kick on low but still no water over the pad. We also engaged the furnace and no water either. After doing some looking yesterday i decided to try and wire it through the nest controller, it seemed like the most direct wiring. After doing this i got the same results with leads me to believe it is the solenoid is defective. The Nest has been in place for a few months now working fine.

 

Nest has been in place for a few months the Humidifier is new to the system

 

Ok, if you have 24v going to the valve, then you have a bad one.
