computer controled switches

[The Bald Ass Prairie Farm]

Hi, I'm new here.
Can some one put me on the right track? I'm looking for info/hardware and
software to run a heat-pump by computer, checking in and out temperature and
have the pump work accordingly.
Any hints are welcome
Thanks Richard

Perhaps it's worth looking at more general purpose equipment? Several firms
make little boxes that will interface temperature sensors to a PC and
provide digital I/O that could be used to drive a pump or valve.

Yes that's what I though "KISS" should be the answer, just left me tinker on
it a while and I'll post the results here

Thanks
