Dixmor does not make a Weepmizer anymore that you can use a Normally closed solenoid valve. The internal board of of the new style Weepmizer with the yellow temperature cable has no provisions for a Normally closed solenoid valve. If you want to use a Normally closed valve your going to have to have the Weepmizer control a relay to open and close the Normally closed solenoid valve.

If you need a NC circuit, you can use a SPDT relay to reverse the switching. Or use a DPDT relay and you can have both NO and NC outputs in two different voltages if you ever need it.
Was you directing that comment to Nuphoenix or me? Surely you know by now I understand relay logic and how to apply it. 
I was asking Nuphoenix Why he would want a weepmizer with a reversed current output 1....I can't think of anything you'd want to run off output 1 other than a weep solenoid? And using a NC weep solenoid would eventually bite you in the arse!

I was expanding on your comment for his benefit. I don't know that he's using a NC solenoid, he may need a NC circuit for something else entirely. Figured it couldn't hurt to let him know there's an option.
The older Weepmizers with the gray temperature cable it was possible to install a jumper on the circuit board inside the Weepmizer so you could use a normally closed solenoid valve. The new Weepmizer with the yellow temperature cable, though they look the same don’t have the same circuit board on the inside that will allow you to use a jumper to make work with a normally closed solenoid valve. Like I said in my earlier post it can be done with a relay on output 1 if you want to use a normally closed solenoid valve.

My system is based on a well in the ER. I have a well pump that recirculates the water from the bays and the IBA. City water is added to the well as needed and used as backup if the power goes out. A NC valve is opened on one side of the tee when the temp drops while the NO valve is held shut till the power goes out.

I guess I can get a NO valve and check valve a put it on the well side so when the power goes out city water wouldn't be wasted in the well overflow. That will allow me to use the NO Weep Mizer.
Since you have a recirculation system and well, why would you want to cycle your weep on and off? A weepmiser is designed to save water running down the drain like most of our systems do. How big is the pump? Voltage/Amps....Electricity to run a pump is cheap...If I had a recirculation system like that, I'd let it run 100% of the time below 36°....That could easily be controlled by any type of cheaper outdoor t-stat that powers on the output at 35-36°....Only issue I see with a well type system is if the power goes out, so does the pump! You have a battery backup or auto start Generator? Or I guess more solenoids and relays to use city water if the electric goes off. .Makes things complicated!

I wanted a central system to control the weep and IBA rail heater. I think my pump cycles too much and using the weep miser will cut that down. I have three t-stats that control three different systems and it would be nice to have one unit that did everything. Every night that it gets cold I have to plug all those units in and set the valves. With the weep mizer and don't have to do anything except plug the NO valve in. Would be nice if the weep mzer had the option of a third output.

As I mentioned, if you use a single DPDT relay you will add four outputs, two NO and two NC, and each could run a different voltage. Output two is just on or off at set temperature.

Because customers leave the wands on the bay floors, which effectively means he's weeping city water. At least that what happens at my wash.

I think I tried that years ago and it was not available. Why do you want this?

I agree with everything 2biz said, but having been stung I take the precaution -
I have the same setup as nuphoenix, HUGE money saver to be weeping the same water over and over!
I have it set up with a weepmizer and NO solenoid.
However, yes, years ago the power went out and the entire wash froze. Of course it was a sunny january saturday, and I was out of town coaching a soccer tournament.
So I added a city water feed into the weep system thru a second NO solenoid, powered all the time to keep it closed, not thru the weep mizer. That way when the power is working I weep recycled water, when the power goes out I weep city water.
I added a third input for weeping hot water, I've chosen to do that on a few occasions.
To manage that "complexity" I built a small manifold. Gauges, ball valves, solenoids, etc. Sounds complex, but not really, I pretty much never have to touch it. I think I have a pic somewhere...

Yep, there it is.
Kindly ignore the fact that the gauges blew out and needed to be replaced when I took this pic
The reason for the outputs being separated is because the furthest bays needed more flow to prevent freezing, so a second pressure regulator solved that quite easily.
And yes, I could just weep more water - but that leads to more weep washers. It always seems to be a balancing act. OK, or maybe I'm just...

what is "beet juice"
PaulLovesJamie
rural 5 bay SS
beet juice is literally the juice squeezed out of beets.
Low freezing point, used by many of us rural folks as ballast in tractor tires.
Also used by some municipalities as a road deicer.

Most cities use magnesium chloride vs. calcium chloride now.
