Help with HE360 wiring

I am hooking up the HE360. So far I hooked up a circuit sensing relay to the nuetral wire on the blower motor, and I am wired to the humidifier and the manual humidistat, but nothing works yet.How do I power it up from there? I do have HUM H and HUM N on my Lennox Furnace. The HUM H is 120VAC while the blower is running. Any advice would be greatly appreciated.

Thanks

he360 wiring help

Upon further research. Can I just come off of the HUM H and HUM N with a step down transformer and just wire up the humidifier and the humidistat and do without the current sensing relay?

that's correct, you can do the transformer, and forget the A50 relay.

HE 360 Help

It appears I have a bad transformer. I hooked the black from hum h the white from hum n and the green to a ground. When I first fired it up I had 24 v coming out of the transformer, But the humidifier would just continually run even when the furnace was down. After an hour it stopped working . I then checked the voltage coming out of the transformer and I had nothing. Does this sound like a bad transformer? Is there anything that could be wired wrong that would cause a brand new transformer to go bad so soon?

Here is how I am wired so far. Black wire from HUM H to Transformer. White wire from HUM N to transformer. Green to ground. From transformer, 1 wire to humidistat and 1 to humidifier. 1 wire between humidistat and humidifier.

should be wired like this.



Ignore the HUM and C, that end wires to your transformer.
