I started out with the Auber that worked ok except when I started using my clip it would have to count down or back up when I flipped my switch between the reg TC and the clip. So I went with the Watlow and it would give me a reading ASAP. From what I have been told the one that Ted sells is also quick but have never tried it with my clip so I can't not say for sure but the guys that has bought my clip and put it on a switch and are using the one Ted sells and they said it works fine. There are other China made ones that also work better than an Auber.
Now every now and then even using the Watlow I have had to unit fire up but only the blower an not the flame and then stop??? Can not figure any reason for the cause. It just moved the air around but also blew heat out the vent.
At one time or the other I have seen a PID just come on and then go off even using them in the electric ovens. Some times its just a click and a click??? The gas heaters take a bit longer to fire up sometimes and I guess the just does a quick cycle and just the blower comes on and then the PID will just shut off and then fire back up like it should. The blower always come on first I guess as a safety feature to blow away any fumes or just to make sure it is working before it fires up.
I would have to go back and read what heater you are going to be using. I have forgot.
Now I also have my unit wired diff than most every one else does so that might be the cause of mine doing what it does??? My unit is plugged into the wall and my PID is just a switch in the middle just like an off and on single toggle switch so that might be the reason mine does that? Most guys that use them let the PID control the power to the unit 100%. The PID sends the 120 to the unit. Where mine is wired just like a light switch and the hot side is all that is being used and it is operating where the built in thermostat was on the unit. All the PID does this way is connect the dots so to speak and there is no load on the PID. At the time I did it this way I didn't realize that the PID would handle the heater but it does. Unless you are using one of the real big ones and then you would need a relay just like the ones used in the elect ovens to take the load off. That way the PID just makes the relay work and would have no heavy load. That is the way mine is wired more or less but I am using the PID as the relay and the unit is plugged straight into the wall. Once the PID comes on then it connects just like the org thermostat did.
Now I will tell you one thing about using the torpedo heater and you really have to monitor your parts well. Because it has the built in blower then your oven heats up parts at diff rates depending on where they are placed or how long the parts are. You can use a louver to help direct the heat flow to up or down or back to front but you can't baffle it because it would try to blow back and cut the unit off. I do not have the heat in my over as much under control as I did when it was electric and had a small fan just moving the air. So I had to learn all over again and then make sure I took IR shots and a few more places or if I could use my clip then have more than one in the oven. I have run as many as four clips and then still double checked with the IR depending on where I was able to clip to. I do it the same as it would be used in a line setup.
Now if you was to build a pro gas oven then you should have better and more even heat distribution I would think? But even a home oven has it hot and cold spots and the cook just has to get used to the oven and what it will do and how to use it.
Hope this hlps you guys some??????????
Time for me to go find somthing to do
