Thanks to Nastec NOW App it’s possible to communicate with all Nastec devices Bluetooth® SMART in order to:
To implement the REMO control system you will need to:
Immediate location of devices on the map.
Real time monitoring of all operating parameters and possibility to start or stop the device remotely.
Remote programming of parameters with possibility of importing and exporting them in .csv format.
Sending e-mail in case of alarm and alarm history reading.
Recording of operating parameters and plotting on graphs.
Capability to capture photos using the smartphone camera.
An inverter allows 4HS to:
Integrated on-board inverter avoids the use of expensive filters and shielded cables reducing electromagnetic emissions to a minimum.
4HS product range meets the needs of commercial and residential markets for water supply, water pressurisation and irrigation.
Compared to conventional solutions, 4HS offers:
Construction characteristics and use of specific materials allow 4HS to be suitable for drinking water applications.
To obtain the latest available firmware version, updated with new features and improvements, simply connect to the device via smartphone and follow the guided update process provided by the app. This ensures that each installation is performed with the maximum capabilities or allows the addition of new functions to existing systems.
In addition to Bluetooth connectivity for control through a smartphone and app, it is possible to install a Wifi or GSM card onboard the device and manage the system remotely through the remo.nastec.eu portal. Therefore, there is no need to install any external communication device or subscribe to expensive telemetry services.
Through predictive analysis performed by the device during operation, it is possible to intervene before a problem occurs, minimizing intervention and repair costs. If the device is connected to the Internet, warning or alarm notifications can be sent via email to the concerned users. For this purpose, a quick configuration from the remo.nastec.eu portal is sufficient.
The device can be connected via the RS485 serial port to external control systems using the MODBUS RTU and BACnet protocols.
To set up the system in a constant pressure application simply install the 4HS pump, connect the CM control module and wire the pressure sensor.
A small pressure tank is normally used to compensate for water loss while the pump is not running.
The control module receives the pressure signal from the pressure transducers and varies pump speed to maintain a constant set pressure regardless of water demand.
In addition to the constant pressure control, CM can also manage the following control modes:
The CM control module manages the operation of the pump from the surface, regulating its speed to maintain the desired pressure constant regardless of the water demand.
Simply connect the pressure sensor, included in the package, and carry out a quick configuration of the pump in relation to the system. Furthermore, during operation, the CM constantly monitors and provides information on the electrical, hydraulic and thermal parameters of the pump, providing complete protection in the event of overvoltages, undervoltages, overloads and dry running.
In the absence of the CM, the signal cables can be used in “ON/OFF” mode as pump start or stop contacts using, for example, a float or a pressure switch.
