temperature management in particular rooms. Thanks to advanced software the controller fulfils a wide range of functions:
•
possibility of controlling up to 22 thermostatic actuators via 8 room sensors (C-7p):
•
one voltage contact for a 230V pump
•
voltage-free contact (e.g. for controlling the heating device)
•
voltage-free contact for controlling the pump operation algorithm (switching between heating and cooling)
•
possibility of connecting ST-507 Internet or WiFi RS to control the system via the Internet
•
possibility of connecting M-7 wireless control panel
•
