Heating bed : which one?

Fairly simple @svdv

  1. Connect signal connection to the input on the ssr + to + and - to -
  2. Connect - from psu to the heatbed directly
  3. Connect + from psu to ssr output and - from ssr output to heatbed. well there isnt realy a ± on the ssr just connection numbers usualy 1 - 4 but you get the point im making hehe :wink:
