    Default Re: controlling a hotwire

    About my schematic: The values for the resistors are just the default values. I know they are not correct. The cap for the input to the opto's, I have no idea what value this should be. Also have no idea yet as to which opto style I want for the zero crossing side of things. Maybe neither? And I see I have connected the top opto incorrectly. I ment to groung the emitter and take the signal from the collector.

    @ Steve, Are you trying to remind me I need a fuse on the wire side?

    @Jerson, I am under the impression using a logic Triac, with 10mA gate will work as I drew it. If I am wrong about this, feel free to tell me and I will add the opto.

    @ Moderators, if this should now be moved to the schematic section, please move it. Thanks
