  • said operating mode is maintained until a user manually deactivates it, for example by pressing a button.

  • the procedure preferably manages the pool water as it is programmed with other operating modes, but ignoring the measurement of water flow and pressure.
  • said predetermined period is about 6 hours.
  • Figure 1 is a diagram of the components of the water management facility that is controlled by the process of the present invention.
  • - Pump 1 Provides the necessary energy to the fluid to pass through the pipes, overcoming the loss of load presented by the installation.
  • the flow that must be driven depends on the action that is being carried out in the installation: filtration, filter or prefilter cleaning, water heating, sensor reading, chlorine production, etc.
  • - Hydrocyclonic Prefilter 2 Performs the separation of solids in suspension by cyclonic technology. When it is full it does not present a significant increase in the loss of load, so that situation is not detectable. Its cleaning is decided by time or by volume of water that has passed through the installation, and is done by opening the solenoid valve that connects it to the drain.
  • Sand filter 3 Filter containing a filter medium based on sand or glass. When it is saturated, it increases its load loss, thus being able to observe an increase in the inlet pressure and a decrease in the outflow. Its cleaning is carried out by backwashing, circulating the fluid in the reverse direction and then driving it towards the drain. In order to avoid accidental emptying of the pool vessel (for example, in case of power failure), said drain consists of an electrovalve.
  • - Selector valve 4 Valve that is connected to the inlet and the outlet of the sand filter, to the conduction coming from the pump, to the pool and to the drain. Depending on the action being carried out, it configures the interconnection between said pipes in one way or another. Possible actions are: Filtration, Washing, Rinse, Emptying, Recirculation and Closed.

On the other hand, if the filter cleaning flow rate is lower than that associated with high-speed filtration, the flow rate would not be reduced during the wash cycle.

  • the selector valve has the ability to inhibit the operation of the pump using wired logic, since the pump must be stopped in order to perform a change of valve position. In this way the "control unit" of the monitoring and control work of the cleaning process is discharged and you must simply ensure that you do not inhibit the operation of the pump for the duration of the washing process. This provides extra security, protecting the integrity of the system against malfunctions of the control logic, as well as facilitating implementation by taking advantage of the ability of the valve to manage the "timing diagram" of the pump during the wash / rinse phase of the filter.

  • This mode of operation is duplicated in the control logic implemented in the selector valve, so, in order to avoid abnormal operation, the parameter of the number of cleanings allowed in Oxh will be set in 24 hours through the ModBus during the start-up of the team. If the selector valve is still in error mode due to more daily cleaning than allowed, the system will reconfigure the parameter via ModBus and the device will be restarted using the external equipment power cut-off relay located in the "control unit" .
