4.1 eserese waya
Carefully follow the wiring diagram below. Ensure all connections are secure and correctly matched to avoid damage to the controller or connected devices. Disconnect power before wiring.
Image 4.1: Wiring diagram for the STC-1000HX. Terminals 1 & 2 are for Cooling (10A/110VAC), 3 & 4 for Heating (10A/110VAC), 5 & 6 for the Temperature Sensor, and 7 & 8 for Power Supply (110VAC).
Ntuziaka waya:
- Connect the main power supply (110V AC) to terminals 7 (Neutral) and 8 (Live).
- Connect the cooling device to terminals 1 (Neutral) and 2 (Live).
- Connect the heating device to terminals 3 (Neutral) and 4 (Live).
- Connect the NTC temperature sensor to terminals 5 and 6. The sensor is non-polar, so connection order does not matter.
4.2 Na-arịgo
The STC-1000HX is designed for panel mounting. Ensure the cutout dimensions match the controller's size for a secure fit. Allow adequate ventilation around the unit.

To enter the parameter setting mode, press and hold the Tọọ bọtịnụ () for 3 seconds. Use the Up () na Ala () buttons to navigate through parameters and adjust values. Press the Tọọ bọtịnụ ọzọ iji kwado wee pụọ.
Ihe ndị a na-ahụkarị:
- SP (Setpoint): The desired temperature.
- HD (Heating Differential): The temperature difference above the setpoint before heating activates.
- CD (Cooling Differential): The temperature difference below the setpoint before cooling activates.
- PT (Compressor Delay): Delay time for compressor protection.
- CF (Temperature Unit): Switch between Celsius (℃) and Fahrenheit (℉).
6. Ntuziaka ọrụ
6.1 Cooling Mode Operation
When the measured temperature exceeds the setpoint plus the cooling differential, the cooling relay will activate, turning on the connected cooling device. The cooling relay will deactivate when the temperature drops to the setpoint.
6.2 Heating Mode Operation
When the measured temperature falls below the setpoint minus the heating differential, the heating relay will activate, turning on the connected heating device. The heating relay will deactivate when the temperature rises to the setpoint.

6.3 Ọrụ mkpu
The controller includes a sensor failure alarm. If the sensor circuit is open or short-circuited, the display will show an error code (e.g., 'EE') and an audible alarm may sound. Replace the sensor if this occurs.
