Can someone help me wire this?

Basically, it is for a humidity control switch.

9 - NC
10 - COM
11 - NO


I have power to the unit. But now I need to connect it to my dehumidifier so it can be switched on and off by the relay depending on the humidity of the room.

The controller is from Love Controls.

The service manual: http://www.dwyer-inst.com/PDF_files/HS_iom.pdf

I am not an electrician...I'm a biologist...so be nice about my stupidity.
 
Am presuming that the 'power' to the relay is coming from some sort of humidistat.

Think of the relay as being an electricaly operated switch and is switched on when power is applied to the coil. You need to switch the dehumidifier with the C and NO terminals.

If you think you could wire it up to a normal switch , then just use the relay instead.

Failing that, GET A SPARK TO DO IT, and get back to your lab and cut some more rats up, or whatever it is you do.
 
Hahaha ok ok I'll go back to the rats. I've got an electrician for the rest of the place I just didn't want to bother him. I'm going to ask him now. Thanks for your help.

I assume the controller is in an enclosure housing a relay/contactor for controlling the dehumidifier, you will need to find out the coil voltage and run a protected feed to terminal 10 and connect terminal 11 (assuming you will set up the controller using normally open contacts) to A1 of the coil of the relay/contactor, you will then have to supply the A2 of the coil with either a permanent neutral or negative.

obviously the feed for the dehumidifier will switch via the relay/contactor with the coil controlled via the humidity controller.

That is all based on assumption of the setup, can you give more details please
 
A quick look: it depends if you want run or fall of humi
If you want run on rise term n/c if you want fall term n/o.
I'm assuming your unit is not greater than 8 amps @230v (thats all the relay can handle)

If the above is correct, then it's a simple matter of the relay providing a supply to the said unit. If your unit is greater than 8 amps, then you will need to use a contactor....
As Mr Darwin said, if you cannot adapt then the gene will become extinct..sorry couldn't resistor it..:)
 
I would have thought the controller contacts would be used to supply a coil voltage to run the dehumidifier via a contactor/control relay etc.
