Automation Hotel Pedasí with adquio ecosystem
Presentation of the case:
In this case we will tell you how the Hotel automation has been carried out Pedasi with adquio ecosystem. On this occasion, it was used to solve the control and automation needs of the 23 rooms and the rest of the common spaces and facilities in the new Pedasí hotel, in Panama.
It is a new 4 * boutique hotel on the Panamanian Pacific coast, in charming Pedasí. Elegance, tradition and modernity come together in its twenty-three rooms and nine spacious suites with terrace, access to the spa, jacuzzi, swimming pool and gym in a privileged natural environment. Opening in November 2020.
The main objective was to centralize the control of 51 controllers, 23 thermostats to solve the following needs:
- Control of opening and closing of windows and doors
- Occupancy detectors and control
- Climate control: temperature, humidity and fan probe
- Control of switched light points.
Usually in hotels with entrance from the inside to the rooms, it would be enough to place a mini-controller per floor and thus be able to satisfy the needs in terms of device control.
However, the particular architecture of the Pedasí Centro hotel, with access to the rooms from the outside, increased the complexity of the installation, since the cable run would have to be done from the outside and this had a negative impact on the aesthetics of the building.
Climate and lighting control solutions
It was decided to use two adquio mini and a adquio lite . On this occasion, the excellent connection capacity of adquio Mini was used extensively, distributing and taking advantage of its 485 buses in a complete way, being as follows:
The first adquio mimi was connected to its first port 485, rooms 101, 102, 201, 202 that coincided in the same vertical with a total of 12 Modbus devices in this port. In the same way, port 2 was used with 15 devices in total. Likewise ports 3 and 4. A total of 51 devices controlled by this adquio mini.
The second adquio mini was used for the complete control of the floor under cover, distributing the 4 485 positions for the control of: Hall, waiting room, warehouse, toilet, sauna, hydromassage, beauty cabin, massage cabin and 4 suites . A total of 6 changeover relay controllers and digital inputs.
Finally, the adquio lite connects through its LAN ports the two adquio mini and of course WAN to the internet. In addition, in its 485 buses, it also manages 6 rooms and 10 common areas such as corridors, reception, administration, laundry, etc. A total of 21 devices on its buses.
The interior and vertical wiring ducts were used to carry out the bus cable run. The configurations of the other ports were similar, connecting rooms on both floors for each controller port to perfectly adapt to the particularity of the building’s installation.
The installation of 3 devices connected to the bus was carried out for each room that have two controllers and a thermostat. With 2 controllers in each room, 16 possible switch relay controls and 4 digital inputs per room are obtained.
A thermostat was installed through the ModBus protocol, with the ability to manage temperature and humidity.
For the control of the led lighting, 7 relay outputs were used for light points. In addition, one was used for lighting phase (switches), one for fan and one for presence, leaving 6 for possible extensions free.
In the installation of each light point, (all are switched), the controller must be the last switch that powers the light point. In order to deactivate all the light points, it must also be the controller that provides the phase to all of them.
Improving energy efficiency
Another key aspect was to improve the hotel’s energy efficiency by automating the operation and shutdown of lights and ventilation through presence detectors in each room. One of the peculiarities of the Pedasí hotel is that the room doors are opened through the mobile phone, via Bluetooth, which means that the presence detection by card was ruled out. For this reason, volumetric and infrared presence detectors were installed.
At this point, it should be noted that the motion presence detector was not enough since, after a few moments without detecting movement, it would give the order to turn off the automatic lighting and air conditioning, even with people inside the room. (Case of guests sleeping or located outside the focus of the detector). That is why a strategy was created in which the presence detectors were combined with a door contact that gives information on when the door was opening and closing.
Attendance control strategy with adquio mini:
If the room is occupied: If presence and door contact are detected, it is assumed that the guest is leaving the room, the unoccupation is started, but with a margin time, if during that configurable time presence is detected again, it is that the guest did not leave the room and the vacancy is canceled. If no presence is detected during that time, the idleness is activated.
If the room is unoccupied and door contact is detected, possible occupancy is activated. If a subsequent presence is detected, occupancy is confirmed. This will not be changed in any case until a next door contact.
With this winning combination, the precision in terms of guest detection was infinitely increased and, as a consequence, the automation of the operation of air conditioning, lights and elevator, allowing to save costs and thus improve hotel efficiency by up to 25%.
On the other hand, the guest also gains freedom and comfort, since he can act naturally without any type of worry to enter and leave his room.
