ST3012 Dual Temperature Controller and Digital Thermostat Controller

Manage two temperature zones from one compact panel. The ST3012 uses dual probes, displays, and outputs for independent heating or cooling. Its heating cooling thermostat supports setpoints, alarms, calibration, hysteresis, and delay protection. Choose the correct 12V, 24V, or 110V–220V version.

Key Features

• Controls two zones independently.
• Range: -50°C to 110°C.
• Listed measurement error: ±0.5°C.
• Dual LED screens show both readings.
• Heating and refrigeration modes.
• Retains settings after power loss.

Why Choose ST3012

A single-output thermostat manages only one sensor and load. The ST3012 combines two channels in one panel, saving space while allowing separate settings. High/low alarms and compressor delay add flexibility.

Perfect For

Suitable for refrigerators, incubators, greenhouses, terrariums, brewing, heaters, cooling fans, freezers, and control projects.

Installation and Safety

Match the ordered voltage: 12V, 24V, or 110V–220V. Rated power is model-dependent—up to 120W, 240W, or 1500W respectively. A qualified person should wire it with power disconnected. Motors, compressors, and high-inrush loads may require an external contactor or relay.

Control Two Zones with Ease
