Temperature Controller

SH-5080T Digital Temperature Controller with Tuya

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.

One controller runs the whole cold storage cycle: it starts and stops the compressor to hold the storage temperature, drives timed or manual defrost cycles, and circulates air with the fan output — with the delays that protect the compressor built in. Touch keys and an IP65 front panel suit damp plant rooms, and the Smart Life app lets you check and adjust it from outside the room.

SH-5080T cold storage temperature controller — compressor, defrost and fan outputs in one panel-mount unit

Three Outputs, One Refrigeration Cycle

Refrigeration, defrost and fan are controlled separately, so each stage can be tuned to the cabinet or room instead of sharing one output.

Compressor output — starts at the on-temperature, stops at the off-temperature, with a settable 0–10 min start delay.
   Defrost output — defrost cycle 0–120 h, defrost time 1–120 min, defrost stop temperature -40°C to +50°C; manual defrost with one key.
   Fan output — runs with the compressor or on probe reading, with advance and lag delays.
   Alarms — HA / LA high and low temperature, E1 / E2 sensor fault, OUT external signal disconnection.

Key Features

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.

Built for Real Installations

Panel-mount in a 92 × 44 mm cut-out. The display, the touch keys and the wiring diagram printed on the housing are the three things an installer works with most.

LED display with 0.1°C resolution, plus a status column for refrigeration, defrost, fan and remote connection.

Touch keys with key lock: on/off temperature, defrost, up and down, and unlock / OK.

Remote monitoring in the Smart Life app: read the current temperature and change settings from outside the room.
