Pumping station controller G422

The controller is an autonomous regulating device developed to control the operation of circulation pumps in solar collector systems. The controller features a modern design and is very easy to use thanks to the user panel with intuitive keyboard and LCD graphics display. The controller is an integral part of pumping and control units ZPS 18e-01, ZPS 18e-01 ECO or ZPS 28-01. The G422-P07 controller is a development of earlier versions, with additional functions. The European energy efficiency directive ErP (Energy related Products) provides for gradual replacement of traditional circulation pumps with new high-efficiency pumps with electronically controlled speed. The G422-P07 controller can be used with both traditional fixed-speed pumps and pumps with electronically controlled speed. Another significant improvement of the G422-P07 functionality is an option to connect the pressure sensor for the solar collector system. This allows to control the system operating conditions, also remotely via the EKONTROL remote monitoring module. Functions of the G422-P09 controller: intuitive and convenient use thanks to a large LCD display selection of the circulation pump type and control using the special operating algorithm; available options: standard WILO ST6 pump, standard pump with reduced energy consumption WILO ST6ECO, electronic pump controlled by special electronic signal PWM: WILO ST7PWM2 ability to connect four NTC10k temperature sensors ability to connect three circulation pumps and/or control valves support of different solar system variants (min. 19), including central heating support and swimming pool heating
