The element draws about 16 amps.
1. What relay would you recommend? I'm biased towards cheap but easily tempted by cool.
2. How do you wire relay? It looks like they have four contacts...
Thanks in advance!
Most solid state relays use DC for their input, the range I've seen is 3-24VDC or 3-32VDC and they draw very little DC power.
Think of it just like a standard one-way toggle switch, but instead of throwing the switch on + off by hand, the DC power throws the switch for you. You'd wire the relay as a switch on one leg of the input for the 2000W element.
As far as wiring it with a STC-1000, you would be wiring one leg (+ or -) thru the STC-1000 on the hot side. (The STC would be making + breaking the circuit to add heat). The output of the STC would then go to the solid state relay, where the other side of the DC would be wired to the other leg of the DC side of the relay.
