HVAC dual-display thermostat

The KEHIPI STC-3028 is a digital temperature and humidity controller built for HVAC systems, refrigeration units and fan installations. It suits installers and facility managers who need a single device to manage both heating and cooling cycles with integrated sensing. The flame-retardant ABS housing protects the electronics in demanding environments. This unit replaces separate thermostats and hygrometers in one compact package.

10 A relay output capacity

The defining specification is the 10 A relay contact rated at 240 VAC, which determines the maximum load the controller can switch directly. It supports resistive heating elements, compressor circuits and fan motors up to that current without an external contactor. The supply voltage range covers AC 110 V to 220 V for global compatibility. Exceeding the 10 A rating requires an additional power relay.

Integrated SHT20 probe included

A 1 metre waterproof SHT20 sensor ships with the controller, providing temperature readings from -20 °C to 80 °C and humidity from 0 %RH to 100 %RH without extra wiring. The probe connects directly to the unit, freeing the installer from sourcing a separate sensor. Calibration and delay-protection functions are configured on the front panel. Builds needing remote sensing beyond 1 metre or higher current loads will require additional components.

Questions about this item

What does the 10A relay capacity mean for the heater or cooler I connect?

The relay can switch loads up to 10 amps at 240 volts AC, so it will directly control most small heaters, fans or compressor circuits without an extra contactor.

How does the 110-220V supply range affect installation?

The unit accepts any mains voltage between 110 and 220 volts AC, letting you wire it to standard household or light-industrial circuits worldwide without a transformer.

What mounting space does the grey ABS housing need?

The controller fits in a standard DIN-rail or panel cut-out; the flame-retardant ABS shell measures to common HVAC control dimensions and the 1 metre SHT20 probe reaches the sensing point.
