I'm inexperienced at electrical engineering. I'm attempting to add a PID controller to an inexpensive, small thermoforming machine. Here's a link to the machine.
I made a schematic of the internal circuitry of the machine. It's not a complex machine, there is no temperature control, there are 2 rocker switches (ON /OFF only)- one for the heater and one for the vacuum pump. The machine is rated at 600W, I'm running it on 120 V. The heater and the vacuum can operate independently or simultaneously.
The PID controller I am hoping to use is fairly common, the Inkbird ITC-106VH:
My hope is to wire the PID so the machine operates the same way it does now. I'll turn on the heater rocker switch, which will power the PID and the SRR. My hope is that I wire it so that this doesn't interfere with the vacuum switch / pump. I need the heater and vacuum to be able to operate independently with the PID inline.
Here is a schematic of the wiring I think will work.
Does this seem like the best way to approach this circuit? Is it even rational? Thanks very much for any insight or help.
