Product name:Split Controller Noise-Free Controlling Application-HTW-61-EW001 Series
 
Item:HTW-61-EW001
 
 
General 
Home Split heating and air conditioning thermostats with Remote Sensor  (HTW-61-EW001) is a Noise-Free room climate controller application for waterinstallations with fan coils. It is designed as a stand-alone device to operate the fan coil unit of a zone and includes a set of functions for 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 backlit display screen, a built in temperature sensor, pushbuttons on the front panel, and inputs and outputs built on split remote relay module for room control.
 
 
This split thermostat application includes two parts:
 
HTW-61-EW001
HTW-61-EW001-RM
 
 
These two parts are communicated via 4-wire connections:
-GND
-12V
-TXD
-RXD
It provides a totally Noise-Free application due to its remoted relay module, which can be placed up to 30 meters far away from the control display panel.
