Guest Room Management System integrated solutions

November 21, 2022

As a main company target, at Legrand Integrated Solutions we offer integrated solutions with Legrand Group products, although this may seem very logical and complicated at the same time. But what exactly is an "integrated solution"?
In upcoming editions of our monthly LIS newsletter, we would like to use these next chapters to provide some real-life examples of how integrations can add value to our products and can put the customer at the center.
We’ll start with BMS: Building Management Solutions BACnet integration
Legrand GRMS (hotel Guest Room Management System) generally allows the guest to control the room functions, but some scenarios within this room may change functionality depending on external parameters. For example, the "Welcome" scenario, which is usually activated when a person enters the room, can have a different action depending on who enters, the guest or the staff. Thanks to the integration of the BMS, this scenario can be different, both for the lighting levels (welcoming or functional) and for the temperature setpoint (comfort or economic).
In many hotels we still see those old fashion cardboard hangers on the door handles to indicate if the guest doesn't want to be disturbed or, on the contrary, if they prefer their room to be cleaned. In the Legrand hotel offer we have long since replaced this function with icons directly on the room control buttons and on the corridor indicators, where the words "MUR" (Make Up Room) and "DND" (Do Not Disturb) are displayed. And not only this because now, using the BACnet protocol and BMS integration, we can also communicate this information to staff, so that they can optimize their working hours.
Furthermore, let's see how, for example, thanks to the integration between Legrand RCU and the BMS of the Netx automation brand, we have the possibility to offer the guest an application for the smartphone to be able to control the lights, the temperature, and the curtains inside his room even more comfortably. Starting by scanning a QR code that the guest receives after checking in, he can download the dedicated app on his smartphone, with a simple and intuitive layout, which will allow him to control the entire room throughout the stay. Of course, the checkout command will break this option.
What about the Heating and Cooling (HVAC) integration?
Let's see more in detail what are the situations that require it and what are the requirements
Within the Legrand hotel offer, we have our thermostats and actuators (on / off or modulating) to control the heating and cooling systems, so in many projects, integration is not even necessary to achieve the best temperature control.
However, as heating and cooling systems are responsible for a large part of the energy consumption in a hotel room, there is a rapid evolution in the systems available and in the way of communicating with them; therefore, here too we see a growing need for integration into our GRMS solutions.
Once the heating and cooling system is fully integrated, we can start modifying the setpoints to achieve the best comfort level for hotel guests, but also, on the other hand, the most energy efficient solution for the hotel.
Guest comfort ranges from changes to the setpoints included in the check-in and welcome scenarios, to the ability to adjust them directly according to their personal preferences. It is also highly appreciated that the Legrand BACnet room controller remembers those specific preferences of the guest, which means that, during a longer stay, the guest will find the same temperature preferences as before upon returning to the room.
Energy efficiency means that, by using the virtual keycard when the guest leaves his room, the "Goodbye" scenario will bring the temperature back to a more economic level, which translates into even more energy saving at the check-out. Also important in the energy efficiency is the fact that, when the guest opens the window, we save energy by adapting the heating and cooling setpoints which are automatically restored afterwards once the windows are closed.
Let's now have a look also on the Access Control Systems
Thanks to the energy efficient options of our Legrand Guest Room Management System (GRMS), we trust that, when no guest is in the room, all the lights are off and the heating/cooling system will be in economic mode. This means that, as soon as the guest enters his room, we must turn on his “welcome scenario” as quickly as possible. The access control integration is one of the options available to accomplish this.
The moment the guest gets permission to access the room from the door lock system, the message is forwarded to the Legrand Room Control Unit (RCU) that automatically launches a customizable “welcome scenario”. This scenario can include functions as lights, temperature, and curtains control.
Based on the person who accesses the room, be it guest or hotel staff, the Legrand RCU will launch a specific scenario. For example, when a guest enters the room, we want him to immediately find his most comfortable centric scenario: cozy light, his preferred temperature setting, and so on. But, when a staff member enters the room, work efficiency scenario must be put first: full light, touch displays buttons lock for easy cleaning, and more economic heating/cooling setpoints.
The access control integration can be accomplished by simple dry contacts to the local in-room RCU or via BMS-BACnet integrations, depending on the system power.
