Control panel with protection grade IP40 complete with leds indicating alarm level, rainwater usage level, top-up in operation and plant fed; normally closed solenoid valve in brass with ½ ” female connections; stainless steel level probes; 2 m power cable with schuko plug; 2 m solenoid valve cable; 20 m probes cable. 

USE: module to be combined with rainwater recovery tanks in which a delivery system is already installed, to allow control of the minimum level of accumulated rainwater and manage topping-up from the mains supply. 

OPERATION: during periods of low rainfall, the rainwater recovery tank empties and it becomes necessary to top-up the water in order to use the services that make use of the harvested rainwater. This operation is carried out by the  

TOP-UP module, simply connecting the solenoid valve to the mains water supply and installing probes inside the storage tank. The system electronics registers the status of the tank through led indicators, providing information on whether the level is sufficient, whether it will soon require topping-up, or whether topping-up is already in progress.
