Stop your heater guessing. This external temperature sensor puts the thermostat right where you need it — at sleeping height in your living space, not buried inside the heater unit or tucked away behind a control panel.
Plug it into your Autoterm Air heater and you unlock proper Temperature Mode: set a target and let the heater cycle automatically to hold it. No more manual power adjustments at 3am. No more waking up roasting because the heater is measuring its own exhaust heat instead of the air you're actually breathing.
