EELECTRON HO04A01KNX-3M THERMOSTAT/HUMIDISTAT 4 KEYS | 8 CH - RGB SWIPER

The HO04A01KNX environmental sensor of the OL-U® KNX® series is a device designed for wall installation and equipped with an LCD display with adjustable backlighting.

Key Features

This device is part of the OL-U® KNX® series and can be configured using the ETS® application program. In addition, it supports communication with the KNX Data Secure protocol.

Sensors and Controls

The HO04A01KNX integrates a temperature sensor and a humidity sensor. It has two two-stage thermostats for controlling two distinct areas, both with an integrated PI controller for controlling heating, cooling equipment, valves, 6-way valves and 2- and 4-pipe fan coils.

The humidity sensor manages the reading of the relative humidity in the environment and allows threshold control with hysteresis for humidification and dehumidification devices.

User Interface

The device is equipped with 4 mechanical buttons (8 channels) to manage on/off commands, dimmers, shutters and blinds, or other programmable command and control functions. On the front side there is a capacitive bar with swipe function for implementing programmable KNX functions.

Visualization and Logic

A freely configurable RGB LED bar is available to display states or other quantities available on the KNX bus. The device has 32 logical blocks for implementing simple expressions with logical or threshold operators, or complex expressions with algebraic and conditional operators.

Predefined algorithms are available for proportional temperature and humidity controls, as well as dew point calculation.

Presence Detection

The device integrates the “Virtual Holder Logic”, which is particularly useful in hotel rooms. Using a magnetic sensor installed on the door and connected to a digital input, it is possible to manage accurate presence information. The presence detection solution can infer the presence of people in the room using one or more dedicated sensors and distinguish different behaviors.

Installation and Compatibility

The device can be installed in a built-in box and is compatible with the main standards (Italian, German, English, Swiss). The dimensions of the device are 71x71x25 mm, while the frame for 3 modules measures 130x92x11 mm.

The power supply is via EIB/KNX bus with a voltage of 21 ÷ 32V DC and a maximum consumption of 30 mA. The operating temperature is between -5 °C and +45 °C, while the storage temperature is between -20 °C and +55 °C. The maximum allowed relative humidity is 90% (non-condensing).

Finitions

The 'Regular' version includes button trims and painted plastic frames. “Fenix” versions are also available with extremely opaque surfaces, soft touch, thermal removal of micro scratches on the surface and fingerprint protection [2] [5>.
