Humidifiers and Dehumidifiers - General Aire 1137 Install On Geo Unit.

I'm doing an install of a General Aire 1137 Humidifier with recirculating pump on my Geothermal unit. It's a Climate Master Tranquility 27.

I have everything mounted and ready to go, but am having trouble with how to connect everything to the furnace.

There are a few different wiring diagrams included with the General Aire instructions.
I cannot find an EAC, ACC, or HUM connection on my panel.

The water supply goes directly to the Recirculating reservoir, which has a 120V hookup. This pumps up through the Solenoid on the humidifier, which is a 24V circuit. The fan on the Humidifier is a 120V connection.
Of course there's the humidistat as well to work in to things.

I'm thinking I need to use a current sensing relay, but am not completely sure how to get everything to work correctly.

I need to supply 120V of power to both the recirculator and humidifier that only is hot when the Heat is on, AND only is hot when the humidistat is closed.
Ditto for the 24 V connection to the solenoid. I need the 24 V connection to the Humidistat to always be hot, and this can probably just piggy back off the thermostat, no?

Also, I tend to leave the fan on all the time to keep the air circulating. Will this be a problem if I use the current sensing relay?

Any help would be appreciated.


Thanks!

I have everything mounted and ready to go,
WHere do you have the unit mounted?

You tied the humidifer's water into your ground water supply?

Recirculating pump? Wasn't this already running before you put in the humidifier?

Sorry, I guess I wasn't very clear.
The unit is mounted on the hot air duct coming out of the Geo.
The recirculating pump I'm talking about is a recirculating reservoir made specifically for the humidifer, so instead of going down the drain, the water is recirculated back into the humidifier. it's mounted below the humidifier, has a float switch in it that keeps the reservoir with 2inches of water all the time.
I haven't done anything to the ground loop pumps, or the ground water lines.

Oh ok!

Had me wondering there what you were doing. I've never heard of any one reusing the water like you are. And how or what is controling the water level? Or is this a set up that Genral Aire offers?

I am not sure if the A50 relay can work on variable speed motor or not?

You could maybe use the line voltage that runs the ground water pumps?

There's a float switch in the reservoir. This was a setup general aire offered, to keep the amount of waste water down. Water where I'm at is pretty expensive.

I could probably use the loop pumps volotage.

I'm not real sure on the Humidistat though.

Here's the description from the instructions.

The humidifier is connected to 120 volt AC circuit through a control relay. THe secondary coil of an isolation tarnsformer, a diode and resister supply 24 Volts DC for the control circuit which also includes the humidistat and relay coil. When the control ciercuit is completed by the humidistat, the relay closes, supplying 120 Volts to the fan motor and 24 volts to the solenoid valve.

YOu don't need to do anything for the humidistat, you jsut wire the two wires from the humidifier right to the humidistat.

The humidifier takes care the low voltage for you.

You just need to tie an outlet to the pump (120 volts AC).

I think I'd only want the pump to run when the humidistat is open as well. Is there any way to handle that?

I went and looked at the install manual for the General Aire 1137, I see nothing about a pump with this model.

the 1137 is a flow though unit,. (goes to a drain)

Is there a kit number that General Aire is using for this set up?

They list it with the 1137-r. The recirc pump is a kit.

I can't find anything on line for me to view, did the kit come with a manual on how this suppose to be wired up?

I am thinking pretty hard on how this suppose be wired up.... I can't come up with how it suppose to be done. Unless ti came with some type of relay kit.
