Micromaster is the distributed intelligence, integrated Room Management system developed by VDA for the Hospitality sector, designed to manage access, climate and lighting. Micromaster’s strong points are energy saving, easy and efficient system control, and absolute guest comfort, both in the bedrooms and communal areas.

A supervision control unit with powerful software and a user-friendly graphic interface makes it possible to communicate with all other control units installed, to control status, processes, functions, settings, and alarms, throughout the entire system.

The peripheral units are connected to the supervision unit by a simple bus cable or via ethernet gateway (IP protocol).

Access Control

Micromaster permits access control by radio frequency using either RFID or BLE (Bluetooth Low Energy) technology.

The most widespread configuration uses a TAG RFID key card reader (transponder). When a guest approaches with their key card, the reader verifies the code against the data in the room control unit. The door opens through an electrical contact. This system can also be used in communal areas.

BLE technology allows guests to use their smartphones to open the door, rather than using a transponder key. VDA has developed a specific app that can be downloaded from itunes/Apple or Google Store, which enables this function on their device.

Climate Control

With over 20 years of experience, the Micromaster system has been used to control every kind of climate control system present on the market.

For radiators, fancoils, splitters, VRV systems, radiant or mixed systems, every control algorithm has already been written, tested and installed. The CON4 Vitrum control panel lets guests interact intuitively with the system, to change fan speeds and set-points, switch off the machine, or set an energy saving regime.

If splitters that cannot be connected to a BUS system are used for room climate control, VDA can manage these via infrared commands that simulate the functions of the remote control.

Lighting Control

Thanks to constant research and development, VDA now fields a vast range of add-ons that allow the main control unit to communicate with every type of lighting appliance available on the market.

Smart Switches

The technological solutions offered by the Micromaster and BIGmaster systems include a range of beautifully designed smart devices
from the Vitrum, Axia, Duetto, and Classic collections.
