RS485 Modbus Remote Control Digital Programmable HVAC Room Thermostat for Hotel

Product ID : HTW-EW002
Product Tags : Hotel Occupancy System
Product Attributes :

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
