I want to wire in a pid controller for the blower to shut down before a different PID controller shuts down all power to boiler . Very Leary to splice into wiring that might fry my control board. This seems simple, but my PID has 120v when it’s on ( out light on) . Are there settings in the controller that would just cut power like a light a switch , like the same as disconnecting the aquastat. How has other Econoburn users done this ?

Are you planning to control it using the flue, or water temperature?

Flue temperature, I have a of controller for the total boiler shut down, i want the fan to shut off at a higher temperature

Been looking for a simple way to do this.
I bought some adjustable snap disc's from the bay,i have one hooked up to a light and it seems to be at an ok position for shutting the light off when the firebox is empty and the coal bed is used up.
I was,am going to get an electrician to hook the snap disk up through a relay to shut off the fan,maybe the complete boiler.

The PID controller that I put in was simple and easy to put in and program . On YouTube there is a guy his name is George from Hops and barley or barley and hops . I used the Inkbird 106 vh ssr controller , he goes through and explains how it works and how to make every connection. Then there is another video on how to program the PID. It works like a charm but I want to go one step further to shut down the blower then at a lower temp the total shut down will turn off all the pumps and boiler controls, eliminating that last trip out to the boiler.

It's the same principal that guys are doing with their wood furnaces. Except they are opening the flap up front up when the temperature gets below a certain point. I'd highly ( cough cough wink wink ) recommend get a PID controller from Auber Instruments vs Amazon or Flebay. Auber has a number that you can call for support too.

I'm pretty these two models will do what you are wanting to do:



I'd probably call Auber and see what they recommend though since you'll be switching 120V vs 24V AC with a wood furnace.

Simple enough to do, especially with 2 separate PID controllers...I agree with @sloeffle , get an Auber, much better quality, directions, and support.
my PID has 120v when it’s on ( out light on) . Are there settings in the controller that would just cut power like a light a switch , like the same as disconnecting the aquastat
Yes, the SYL-2342 linked above is rated for 10A at 120v.
Are you wanting to shut off based on flue temp? If so, you will need a 3-4" long K type thermocouple too...

Not quite the same but there is a simple timer on my Jetstream for the blower. A few dozen burns and can guess the time for a full load of softwood and hard wood pretty well already. Once blower is off the aqua stat scavenges the heat out with the circulator over the next hour or two.

I have an idea that I need to check out but I have a few things to wrap up , so it might not be for a day or 2 . I’m thinking my solution is in the programming.

Today I was able to wire my PID controller through the aquastat wiring . I’m using the Inkbird 106 vh with ssr , the aquastat will shut down the blower when hitting the high limit and the Inkbird PID will shut down the blower at a preset low temperature like around 160 and the other PID controller will totally shut down the boiler and pumps at a lower setting than the blower PID. The PID that controls the blower is just an unpowered switch, the wiring is a little different and the programming is different. I’m not sure if the settings are different for a different PID controller, but if you use the Inkbird, pm me and I’ll send you a wiring diagram and the settings parameters.
