The UCS30 series are free configurable controllers designed for controlling large HVAC systems. Thanks to the large number of inputs and outputs and the huge programming capabilities, the controllers enable the control of HVAC systems in a very wide range. Any application can be entered directly from the keypad and they do not require any external software tools such as a computer, programmer or memory card. UCS controllers have a very rich and flexible software covering all issues related to HVAC systems. Despite the extensive software, they are very easy to use. Built-in function blocks can be freely configured in an easy and intuitive way. The MENU system is organized in a very readable way and works in an interactive way, adapting to the defined application by the user. Elements related to unused functions and parameters are removed from the MENU system. UCS controllers, unlike freely programmable controllers, do not require external software tools or create their own control algorithms by the user, as they have built-in algorithms and functions for full control of HVAC systems. To create your own applications, all you need to do is to configure the controller step by step from the MENU system. The UCS30 series has a real-time clock with a weekly work schedule. You can define up to five time zones for each day. The time zone is determined by the start and stop time of the system. Within each zone, all setpoints are set: temperature, humidity, pressure or CO, gear or fan speed etc. Also, you can disable or enable the operation of some devices within these zones.
