4. Guida all'installazione
4.1 Schema elettrico
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).
Istruzioni di cablaggio:
- 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 Montaggio
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.
5. Impostazione e configurazione
5.1 Accensione/spegnimento
Premere e tenere premuto il tasto Energia pulsante (
) for 3 seconds to turn the controller ON or OFF.
5.2 Impostazione dei parametri di temperatura
Per accedere alla modalità di impostazione dei parametri, tenere premuto il tasto Impostato pulsante () for 3 seconds. Use the Up () E Giù () buttons to navigate through parameters and adjust values. Press the Impostato di nuovo per confermare ed uscire.
Parametri comuni:
- SP (Setpoint): La temperatura desiderata.
- HD (Differenziale di riscaldamento): The temperature difference above the setpoint before heating activates.
- CD (raffreddamento differenziale): The temperature difference below the setpoint before cooling activates.
- PT (ritardo del compressore): Delay time for compressor protection.
- CF (Temperature Unit): Passa da Celsius (℃) a Fahrenheit (℉).
6. Istruzioni per l'uso
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 funzioni di allarme
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.
7. Menu Parameter Settings
To access and modify the advanced parameters, press and hold the Impostato button for 3 seconds. Use the Up/Down buttons to navigate and adjust values.
