HO04A01KNX

OL-U KNX Thermostat Humidistat – FENIX Edition

The HO04A01KNX environmental sensors are devices of the OL-U® KNX® series for wall installation for 2 and 3 modules (502-503) and are equipped with an LCD display with adjustable backlight.

Technical highlights & Configuration

Core Features

The device integrates temperature and humidity sensors (HO04A01KNX only) and two two-stage thermostats for the control of two distinct areas, both with integrated PI controller for driving heating, cooling, valves, 6-way valves, 2-pipe and 4-pipe fan coils. The humidity sensor manages the reading of the relative humidity of the environment and allows the control of humidification and dehumidification devices at thresholds with hysteresis. The device is equipped with 4 mechanical keys (8 channels) for managing on/off commands, dimmers, shutters and blinds, or other programmable command and control functions. On the front side of the HO04A01KNX devices there is a capacitive bar with a swipe function for the implementation of programmable KNX functions. A freely configurable RGB LED bar is also available for displaying statuses or other quantities available on the KNX® bus.

Technical Data

The device has 32 logic blocks with which to create simple expressions with logical or threshold operator, or complex expressions with conditional algebraic operators and use predefined algorithms such as proportional temperature and humidity controls or dew point calculation. The device also integrates the “Virtual Holder Logic”. The field of application is the hotel room: by means of a magnetic sensor installed on the door and connected to a digital input, accurate presence information is managed. The presence detection solution can infer the presence of people in the room using one or more dedicated sensors. It also detects an accidental presence and is able to differentiate multiple behaviors.

Mounting & Compatibility

The OL-U® KNX® series is available in various colors and can be installed on 2 or 3 modules (502-503) and is compatible with the main standards (Italian, German, British, Swiss). The device can be configured via the ETS® application program and can communicate with the KNX® Data Secure protocol. KNX® communication interface is included.
