Product Description

Smart Hotel Thermostat EC Fan Room Temperature Control

 

>> 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.

The device is a compact unit that includes a large touch screen operated Black Color Negative Screen/ White Color LCD Screen optional, a built in temperature sensor, real touch screen keypads on the display part, and inputs and outputs built on split remote relay module for room control.

This split thermostat application includes two parts: Display Part and Relay Module Part.
These two parts are communicated via 3-wire with carrier transmission technology connections, up to 50m non- loss communication:
-GND
-12V
-DATA
It provides a totally Noise-Free application due to its remote mounted relay module.
