Hi to you wonderful Experts, To control a water heater of 3KW6 at 220V I bought a couple of BTA40 triacs. My friend bought a Chinese dimmer with BTU40 and I copied it (see attachment). The Prob is that it has to use a 2W Pot and they're not cheap. Q: Is there a way of curbing the current to the Pod so that I can use an ordinary Pod, instead? The circuit below the Chinese one I found on the Internet. This one did not ask for a 2W Pot. Please check if that's right, for I don't want burn them out, just to find out.
