Item:HTW-61-EW001
  
>> General 

Hotowell Functional Split Temperature Controller Noise-Free Window Card Key Card Lighting Modbus Thermostat Controlling Application- (HTW-61-EW001) 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.
