Raising healthy chicks starts with consistent warmth. In this guide, you’ll learn how to wire and program the STC-1000 digital temperature controller to power your brooder’s heater automatically. This simple setup uses only the heating relay function, no cooling required.
Why Use the STC-1000?
The STC-1000 is a versatile, affordable temperature controller widely used in poultry, fermentation, aquariums, and greenhouses. For brooding chicks, it automates heat delivery — keeping temperatures stable without manual checking.
What You’ll Need
STC-1000 temperature controller
Heat lamp or boiler
NTC sensor (comes with STC-1000)
Short electric wires (4 pcs, about 2cm each)
Electrical plug (AC 110V–220V)
Electrical tape (black)
Screwdriver
Step-by-Step Wiring (AgriBuzz Method)
We simplify your connection using a short 4-wire loop method:
1. Prepare wires:
Cut 4 short jumper wires (around 2 cm).
2. Connect AC to Terminals 1 & 2:
Terminal 1 = AC Live
Terminal 2 = AC Neutral
3. Bridge Terminal 1 to Terminal 6 (relay power) 4. Bridge Terminal 2 to one side of the heater 5. Connect Terminal 5 to the other side of the heater
6. Use electrical tape to insulate all wire joins. This ensures safety and avoids short circuits.
7. Insert sensor wires into Terminals 3 and 4. Place the sensor inside the brooder at chick height.

Programming the STC-1000
Hold “S” button for 3 seconds to enter setup mode.
Use arrows to navigate:
F1: Set target temperature (e.g. 35°C for chicks)
F2: Set difference value (e.g. 1°C)
F3, F4: Leave default or consult manual.
Chick Temperature Guide
| Chick Age | Recommended Temp |
|---|---|
| 0–3 days | 35°C |
| 4–7 days | 33°C |
| 8–14 days | 31°C |
| 15–21 days | 29°C |
| 22+ days | 28°C |
Reduce temperature by 2°C per week using the F1 setting.
Safety Tips
Always use ceramic heat bulbs for safety and durability
Do not place the sensor directly under the heat lamp
Keep STC-1000 device mounted outside the brooder
Use black electrical tape on all joins to prevent shock
