What tasks does the PR103 programmable relay solve?

Our ethernet relay PR103 can be used as an Ethernet or RS-485 controller in a wide range of applications:
For example as an air conditioning controller, for controlling a damper, colophier, fan in a ventilation system. In general, the automation controller PR103 is widely used in HVAC. Often our controller is called HVAC controller.
Also our industrial contoller is widely used for pumps. You can find such a typical application at: https://akytec.de/en/blog/water_tank_management .
Often our relay is used for lighting automation. Both standard lighting in the enterprise using touch sensors or switching lights on and off according to time, and thanks to Ethernet our controller is used for emergency lighting and warning systems in the enterprise.
To summarize, our affordable controller PR103 can be used to automate any secondary technological process in a company.
