[Coco] OT: Heat / A/C controller replacement

[Frank Swygert]

Walk into Wal-Mart and pic up a cheap digital thermostat. Nothing much has changed with basic operation. Simple digital t-stats are made to replace the old round Rockwell and similar t-stats from the 70s, so unless you had some unique wiring it should work fine. You can get internet controlled wired and wireless t-stats, but they connect to the HVAC unit the same as the old ones do -- a four lead telephone wire.

Hi,

My Heat / A/C was installed ~ 1971.

Today's Heat / A/C controllers likely have an wireless internet address.

I just am looking for ideas as to how a old heat / A/C controller could be
used like the one I built ~ 30+ years ago.

Links to the old controllers available today might be a starting point.

I fear walking into a hardware store would produce smart phones to control
Heat / A/C from Perth.
