Stc-600 Temperature Controller Manual Pdf May 2026

The STC-600 is a dual-relay temperature controller. Unlike bare-board units that require complex wiring (like the STC-1000), the STC-600 is often sold as a pre-wired unit with standard AC outlets. However, many DIY versions and industrial models require manual wiring.

Key Specifications (From the Official Manual):

Because the STC-600 is cloned by several factories, the STC-600 Temperature Controller Manual PDF can vary slightly. However, the core programming logic (using the SET, RST, and arrow keys) remains universal. Stc-600 Temperature Controller Manual Pdf

Power Input:  1 (Neutral) – 2 (Live 110–220V)
Sensor:       3 (Sensor+) – 4 (Sensor-)
Cooling Relay: 5 (COM) – 6 (NC – to compressor/cooling)
Heating Relay: 7 (COM) – 8 (NO – to heater)

⚠️ Important: Do not exceed relay current rating. For inductive loads (motor, compressor), use an external contactor.

| Code | Parameter Name | Default Setting | Recommended Range | | :--- | :--- | :--- | :--- | | F1 | Temperature Set Point (SV) | 25°C | Your target temp | | F2 | Differential / Hysteresis (HY) | 2.0°C | 0.5°C - 5.0°C | | F3 | Cooling Delay Protection (PT) | 3 Minutes | 0-10 min (3 min saves compressor) | | F4 | Temperature Calibration (CA) | 0.0°C | ±5°C | | F5 | Unit Selection (CF) | 0 = Celsius | 1 = Fahrenheit | | F6 | High Temperature Alarm (AH) | 99°C | Set above your max desired temp | | F7 | Low Temperature Alarm (AL) | -40°C | Set below your min desired temp | The STC-600 is a dual-relay temperature controller

The most common confusion in the STC-600 Temperature Controller Manual PDF is how the two relays work together.
