just to verify you are not using iaq stat? What model humidifier? DO you have a humidistat?

 

[hvactech126]

Do you have the control module from the stat wired at all?

 

[hvactech126]

ok. do you conventional A/c or heatpump

 

[hvactech126]

one more question.... outdoor sensor or no? and does humidifier come with a transformer?

hum1 to
r right above it
hum2 to solenoid valve
C also to other side
of solenoid valve


out1 and out2
to outdoor sensor


Preferably it would be hooked up differently using a 20va transformer to provide power for the hum. this would ensure that you were not robbing power from the furnace which on some furnaces has caused problems

I have this stat and install this stat all the time, I LOVE IT!!!!

let me know if you need help with the setup functions

 

[hvactech126]

leave them

 

[hvactech126]

in setup you only want the hum to run with the furnace. also you can check operation by going to the test function in setup

The humidifer doesn't seem to be working. I have one of the solenoid wires to C on the module, and the other to hum2, and hum1 jumped to RH. I may check the valve, by wiring 20v straight into it.

check for 24v between hum 2 and c when it is calling for humidification
