I’d like to extend the temperature range of the VM-137 thermostat. It needs to have an upper limit of 112 F or above. How would I do this?

Instructions are printed on top of the PCB.
It will tell you what resistors to change.

Thanks for the reply. I actually did see those instructions on the board, but they seemed a little cryptic to someone like myself; a relative newbie when it comes to such stuff and I’ve had the board a long time. If there were any build instructions with the kit I’ve long since lost them and forget if that was ever pointed out. Anyway, I get it now and will see what I can do with the temperature setting. Again thanks for your reply.
