INKBIRD ITC-308
US heating and cooling controller
Buyer feedback ↓INKBIRD ITC-308 switches separate heating and cooling outlets using a remote temperature probe. It is a plug-in controller, not a heater, cooler or humidity sensor.

THE QUICK TAKE
Is it right for you?
Choose it for simple temperature-based control of compatible plug-in equipment. The separate probe lets you measure away from the wall outlet, and the two labeled outputs make the heating/cooling roles clear.
Skip it if you need humidity control or remote phone access. This is the standard temperature model. You must also confirm the connected appliance restarts after power is switched; a touch-button device that stays off will not become automatic just by plugging it in.
01 / BUYING NOTES
Before you buy.
Connect each job to the right socket.
The outlets have separate heating and cooling roles. Connect only equipment that resumes operation when power returns, and stay within the controller and appliance ratings.
The probe controls the decision.
Put the temperature probe where the controlled temperature matters. A waterproof probe rating does not apply to the controller body or socket bank; keep those dry.

02 / AMAZON REVIEWS
The buyers’ view.
Owners differ on programming: some found setup straightforward, while another needed time to decipher the instructions and abbreviated settings. One found the printed manual too small to read comfortably and used a downloaded copy instead.
Owners report dependable operation in workshop and indoor-growing setups. An owner using a modified camper air conditioner reported warming cords and a display glitch, despite also describing effective temperature switching.

Goomba Grows introduces the ITC-308 in a growing setup. The linked seller listing differs from this ASIN, so the video establishes the controller family rather than the selected package.

The ITC-308 distinguishes heating from cooling and provides setpoint, differential and delay controls. Its probe rating must not be applied to the mains-powered body.
