Controlador de temperatura del termostato de pantalla de vidrio templado plano 110vac, con ventilador CE y válvula reguladora
HTW--61-EW002 es un controlador climático interior sin ruido para la instalación de agua con bobina de ventilador / EC fan / válvula reguladora. Está diseñado como un dispositivo de comunicación rtu modbus para operar la unidad de bobina de ventilador / ventilador EC / válvula reguladora en el área, incluyendo un conjunto de funciones de control de iluminación, ocupación del área y control climático basado en la posición de la ventana. Por lo tanto, se proporcionan altos niveles de comodidad y un control climático adecuado para garantizar el máximo ahorro de energía.
>> General
HTW-EW002 is a Noise-Free room climate controller application for water-installation with fan coils/EC fan/Modulating valve. It is designed as a RTU Modbus communicated device to operate the fan coil unit / EC Fan / Modulating Valve of a zone and includes a set of functions for lighting control, zone occupancy and window position based climate control. A high level of comfort and appropriate climate control to ensure maximum energy savings are thus provided.
These two parts are communicated via 3-wire with carrier transmission technology connections, up to 50m non- loss communication:
-GND
-12V
-DATA
