Climate Control

The home automation system for hotels, offices, hospitals, … that we offer manages the air conditioning in order to minimize energy costs without reducing the comfort of users. The system is designed to be used by the technicians of the establishment, so it is simple and intuitive.

Both two-pipe and four-pipe air-conditioning systems can be controlled. The most common installations are two-pipe systems, with 3-speed fan coil and valve. Four-pipe systems can be controlled by electromechanical valves or proportional valves with PID algorithms in very demanding installations.

A probe can be installed in the fan coil pipes to determine whether the heat or cold is reaching the room correctly. In this way the technician can make an early detection of a clogged valve or air pocket.

In all versions, the philosophy and algorithm are very similar. Inside the room the system is divided into two parts. One is the control unit, installed inside the electrical panel or hidden in the false ceiling. The other part, with which the customer interacts. We offer several types of consoles, from classic to modern, all with a pleasant and intuitive design. With it, the user can indicate to the system the desired setpoint temperature, regulate the fancoil power or disconnect it.

The system will detect the presence or not of people and by means of an algorithm will decide the most suitable temperature. The algorithm has different modes, occupied, VIP, unoccupied, ice, dehumidification, anti-freeze and emergency. It also takes into account schedules and outside temperatures.

PIR motion sensors, window sensors and door sensors are connected to the control unit. These sensors indicate whether someone is inside the room or not. The detection system does not require a card for operation, so it is compatible with traditional key and card holder locks.

In a simplified way, if motion is detected inside a room with the door closed, the system will assume that there is presence inside that room. On the contrary, if the door is closed and subsequently no movement is detected, it will infer that there is no one in the room. In the latter case, the system will temporarily switch off the climate and lights. The air conditioning is also switched off if the system detects that windows or doors are open for a configurable time.

The controller has relay, triac SSR or transistor outputs, which act on the air conditioning, the lighting system, curtains, blinds,… In order to achieve greater savings, the system can be configured with a night schedule, which allows a programmed deviation of the room temperature assuming that the users are most likely to be sleeping.

For example, if a user selects a temperature of 25ºC in summer, at night with an allowed deviation of 2ºC the room temperature will progressively increase from 25ºC to 27ºC. If the user acts on the console, the window, the door and optionally on the lighting system, the system will recover the normal temperature of 25ºC for twenty minutes.

The control unit can be connected to the server via a twisted pair bus running through all the rooms, or via the Ethernet network taking advantage of the current GPON paradigm.

The system remains switched off.

The user can select the setpoint in a range allowed by the establishment.

If the system detects presence and windows and doors are closed, an attempt will be made to bring the temperature closer to the selected set point.

If the user is not in the room, the air conditioner can be turned off or a comfort temperature set by the establishment can be selected as the setpoint.

When a customer enters a disconnected room, the climate control can be set to:

• a) switch from comfort mode to off.
• b) to operate with a standard hotel locker.
• c) to operate with the customer’s last setpoint.

Optionally, an ecological set point temperature can be enabled in the system. This is automatically calculated from the outdoor temperature and humidity.

Designed for customers who deserve special attention. The user can select the desired temperature regardless of whether or not he/she is inside the room. This mode can be set for a certain duration, after which it automatically switches to occupied.

The system tends to reach a temperature configurable by the facility manager, called the holding temperature. The objective is that the room does not reach extreme temperatures when not in use.

If the system is connected to the reservation system, the unoccupied mode will be activated automatically when the room becomes vacant.

The air conditioning system is turned off and will only start up when the temperature drops below 5ºC.

The system maintains humidity below a programmable level. The system can be programmed to operate at certain times of the day.

It is designed to prevent humidity in installations near the sea or in tropical areas when they are out of use for long periods of time.

A temperature is remotely selected and the system tends to maintain it.

The status of the temperature sensor is ignored and the fan coil and valves are set to a fixed state.
