110Vac Flat Tempered Glass Screen Thermostat Temperature Controller With EC Fan and Modulating Valve

>> 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
