temp controller

maybe im not googling the right question but do they make some kind of controller that you plug a heater and a a/c unit into and when the room gets cold the heater kicks on and when the room gets hot the a/c kicks on. maybe a 10 degree swing.. thanks for any input or the proper name.

It's called a thermostat and they are built in to heaters and ac's.

Put a line voltage cooling thermostat on the AC and a line voltage heating thermostat on your heater. Make sure they are rated for amps being drawn. Tweak settings to tune deadzone / swing

C.A.P. / Green Air / Sentinel all make turnkey environmental controllers.

so they dont make somthing simple you just plug into. my aquarium chiller plugs into a controller but it doesnt do heat too.

i knew i was asking the right people, thanks
