12-pack 110V digital thermostat outlet
This pack contains twelve HUAREW HWX-Backlight Controller units designed for 110V circuits. Each controller manages heating or cooling loads up to 16A and 3680W through a built-in socket. The 2.24-inch LCD shows status clearly without a backlight. The white enclosure uses PC flame-retardant material and measures 6.3 cm x 8.4 cm x 14.5 cm.
Verify voltage probe length and load type
Confirm your supply is 110V AC at 50 or 60 Hz before installation. The included NTC 10K sensor probe is 1.7 m or 5.6 ft long; ensure this reach suits the measurement point. The relay output handles resistive loads up to the rated 16A; inductive loads such as large compressor motors may require an external contactor not supplied.
Continuous operation at rated current
At the maximum 16A output the internal copper contacts and flame-retardant housing are rated for sustained temperatures up to 120 °C. The controller cycles the connected heater or cooler to maintain the set point within ±1 °C accuracy. Calibration offset of -9.9 to 9.9 and memory retention keep settings stable during long-running duty cycles.

Questions about this item
Does the 12 pack include the NTC 10K temperature sensor probes, or must they be purchased separately?
Each of the 12 controllers comes with its own 1.7 m / 5.6 ft NTC 10K probe, so no separate sensor purchase is needed.
When would I choose the heating mode versus the cooling mode on this controller?
If the start temperature is set lower than the stop temperature the controller runs heating; if the start temperature is higher than the stop temperature it runs cooling.
What does the 16 A / 3680 W output rating mean for the heater or cooler I plug into the socket?
The connected heating or cooling device must not draw more than 16 A or 3680 W, otherwise the controller’s relay could be overloaded.
