Underfloor systems need a software program to regulate their operations. The software is used to sense and compare the real state with the target state of the internal environment. The program then draws a conclusion for an action to be taken to control that internal environment.
Both central and terminal controllers have a programmable software program installed in them, and this means that it is possible to customize a program code to meet the occupant’s preferred conditions. The software features include set points, time schedules, timers, usage logs, and alarms.
On the other hand, the unit controllers have digital and analog inputs which allow the measurement of pressure, humidity, and temperature. Additionally, the units have digital and analog outputs which control the transport medium.
Digital inputs are the contacts from a control device. These inputs relay the contacts used to start and stop the equipment. Analog inputs, however, are the current or voltage measurements from a variable sensing device. These inputs are typically the voltage or current signals used to control the movement of the medium control devices like dampers, motors or valves.
More complex systems have a building automation system program which allows the building owners to have more control over the cooling or heating units. The software allows the building owner to check the system and respond to the alarms set off by the system remotely.
Additionally, homeowners can use the software to schedule the system for occupancy. At times, the program can directly control the components of the underfloor system. Various interfaces are often used in these systems, but this depends on the software.
For instance, today’s software programs which are installed in AirFixture Under Floor Air Distribution Systems allow centralized control and monitoring. This does away with the need to buy more complex and costly underfloor systems. In addition, these programs can provide remote control operations for all underfloor systems over the internet, incorporating a simple and user-friendly interface.
