Degassing takes place within the hydraulic part using a diaphragm pump in conjunction with a vertically arranged brass vacuum spray tube. This is equipped with a vacuum spray nozzle, dipstick-tube degassing unit and pressure monitoring. To protect it against dirt, the unit as a whole is located in a housing made from expanded polypropylene with an opening maintenance cover.The Control Smart controller is integrated in a robust plastic housing in which both the power and communication electronics and the control panel with dirt-resistant plastic foil keyboard are housed. Bluetooth is integrated as standard as a communications interface. The controller has a fully automatic microprocessor controller with time function, differentiating error and parameter memory, LED display of the operating modes and general error messaging, visualisation of the control states for system pressure and all relevant operating and fault messages using the Control Smart App via Bluetooth communication.Communication electronics comprising:

RS485 port (galvanically isolated) for the connection of optional communication components
Floating output for forwarding of the group message
Digital input for signal processing of a contact water meter
Analogue input for measuring the conductivity

Input for makeup functional request via external signal

Control Smart works with a plug & play function for independent system pressure detection, enabling convenient wireless operation via an app for smartphones and tablets running either iOS or Android to provide simple commissioning as well as visualisation of system operation. The following functions are available:

Automatic setting of the time and date
Setting and adjusting the minimum operating pressure p0
Switch-on times for permanent and interval degassing can be freely specified and entered by the operator
Free configuration of day of the week and time for interval degassing operating mode including a summer function
Status, warning and error display relating to facility pressure and operating conditions including diagnostic instructions and handling recommendations
Automatic software updates
