Honeywell HE360 Humid Wiring

I'm sort of confused. The HUM terminal on the board in your furnace is simply a 24V connection. Without looking at the diagram that came with this unit, it's hard to say. If there is a set of wires labeled 24V, then those go to the board. One goes to the HUM terminal and the other to common. Didn't this unit come with a wiring diagram?

The wiring diagram shows the yellow wires going through the humidistat and to a sail switch. There is no external 24V input from a furnace in this set-up. There are two red wires they say not to use on this model unless you buy the electronic humidistat controller - I'd rather not. There is another wiring diagram that shows the two yellow wires going to a current sensing relay on the blower motor. I would rather somehow use the 24V HUM terminal on the furnace, I just don't know what to connect to it ( i would guess red) but then what do I do w/ the yellow. I'm assuming the internal transformer is supplying 24v on the yellow wires for the loop through humidistat and the sail switch/sensor relay and i would not want to send that into another 24v source.

Thanks

If anyone would like to take a look at the instr manual: http://hbctechlit.honeywell.com/techlit/PDF/69-0000s/69-1175.pdf

This clears things a bit. First of all with this model, it is self powered, so you won't be using the HUM terminal on the board in your furnace.

Second, you will need to purchase either a sail switch or a current sensing relay to prove to the humidifier that the fan is running.

The current switch would be my preference. This installed over the neutral (white) lead going to the blower motor.

These are your only options if you opt not to use the H1008. Hope this helps. Good luck.

Sorry HKestenholz,

not trying to sound like a broken record, you type much faster than I.

Thank you for your responses. I have a better understanding.

Please help, how to connect Powered Humidifer HE360A to Programable RiteTemp 8082c Thermostat.

I have a "powered humidifier" Honeywell HE360A that plugs to 115V.

The wires in pwr hum send 24V !!

I was told (by rude RiteTemp) to connect hum to H and RH in Tstat but that makes no sense, cannot send 24V from hum to Tstat, and 24V from Tstat (RH) to hum, right???

I don't want to use the Hstat that came with hum, want to use 8082C to control humidity.

I just installed the HE 360 and wired the two
Yelllow wires with the humidstat seriesed in the circuit and the pressure switch for
The induced draft blower and everything works great. Is this ok to use the pressure switch for
The ID fan to control
The humidifier ?

I agree the instructions that come with the humidifier are useless when it comes to the pressure switch... but I found this video that is pretty good....
