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.

Climate control + lighting (Lighting auxiliary):
In this operating mode, the controller may be switched on or off at any time through the front panel pushbuttons,
since there is no keycard switch contact available to block the device. The keycard switch contact is in this case
configured to operate as a lighting contact, which acts on the AUX output every time the input changes its state
(refer to installation diagrams). This operating mode is only possible on 2 pipe systems.
