Temperature Controller
Keywords: cold storage temperature controller, SH-5080T thermostat, defrost fan controller, Smart Life wifi temperature controller, digital temperature controller for freezer
Digital cold storage temperature controller with compressor, defrost and fan outputs, a -40°C to 99°C measuring and controlling range and Smart Life WiFi remote monitoring.
1. Refrigeration, defrost and fan outputs — three independent control outputs for cold storage: the compressor output holds the storage temperature, the defrost output runs timed or manual defrost cycles, and the fan output circulates air with configurable start and stop delays.
2. Wide temperature control range — -40°C to 99°C, with 0.1°C resolution and ±1°C accuracy, reliable across a broad range of conditions.
3. High-resolution digital display — clear LED readout with real-time temperature updates for accurate and easily readable monitoring, and the defrost probe temperature can be checked with one key.
4. Comprehensive safety features — high / low temperature alarms (HA / LA), sensor fault alarms (E1 / E2), external signal disconnection alarm (OUT), and compressor start delay protection that prevents damage from excessive start / stop cycles.
5. Smart Life WiFi remote control — check and control the controller remotely through the Smart Life app (2.4 GHz WiFi only).
6. Energy-efficient and durable design — touch keys with high-precision digital capacitance measurement are unaffected by water droplets, and the ultra-thin integrated front panel carries an IP65 protection rating.
