5. Configuración e funcionamento
5.1 Acendido
After completing all wiring, apply power to the controller. The display will show the current temperature measured by the room temperature probe.
5.2 Axuste da temperatura
- Preme o SET button once. The display will flash the current set temperature.
- Usa o Up (▲) ou Abaixo (▼) buttons to adjust the desired temperature.
- Preme o SET button again to confirm and save the new setting.
5.3 Configuración de parámetros
Advanced parameters for cooling differential, defrost cycles, fan operation, and more can be accessed and adjusted through a dedicated menu. Refer to the detailed parameter list in the full technical manual for specific codes and ranges. Parameters can also be set and copied using a copy card for quick configuration across multiple units.
6. Modos de funcionamento
6.1 Modo de arrefriamento
When the measured temperature rises above the set temperature plus the cooling differential, the compressor relay activates to initiate cooling. It deactivates when the temperature drops to the set point.
6.2 Modo de desconxelación
The controller supports various defrosting modes (e.g., timed defrost, manual defrost). During defrost, the defrost relay activates, and the compressor typically turns off. The defrost cycle duration and frequency are configurable parameters.
6.3 Xestión de ventiladores
The fan output can be configured to operate continuously, only during cooling, or to turn off during defrost cycles, depending on the application requirements.
7. Mantemento
Regular maintenance ensures the longevity and accurate operation of your temperature controller.
- Limpeza: Limpe o panel frontal cun suave, damp pano. Non use produtos de limpeza ou disolventes abrasivos.
- Inspección: Periodically check wiring connections for tightness and signs of wear or corrosion.
- Comprobación do sensor: Ensure temperature probes are clean and securely placed.
8 Solución de problemas
Esta sección aborda problemas comúns que podes atopar co controlador ETC-3000A.
| Problema | Causa posible | Solución |
|---|---|---|
