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.
--1 EC fan output
--1 modulating valve output
--3 speed fan relay
--1 on/off valve output

>> 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.
Energizing the device
The device can be configured to start up from the off position or in operation after a voltage drop.
If the display part appear Err icon, it means there is an anomaly in the device; the device should be replaced.
During the first few seconds the screen will display some digits, which will subsequently disappear.
