No more guessing if the AC is working
The intuitive user interface of Vari PRO room controller makes setting the room temperature easy. The controller displays both the current temperature and the new set point, which are the key parameters for the user. The graph shows to which direction the temperature is controlled by the air conditioning to reach the new set point, and the time it takes to reach it. The main display of the Vari PRO controller can also be configured in different ways depending on the usage.
The fan speed is automatically controlled in relation to the set point temperature, with a possibility for manual override.
Informative user interface for operations and maintenance
The Vari PRO room controller provides vast information and diagnostics possibilities, which guarantees excellent user experience. Information about the internal parameters of both the unit and the controller itself, and counters for energy usage, and unit and component service times can be viewed in the service menu of the room controller. The same information can be read to the building management system via Modbus fieldbus connection. The information can be utilized for both proactive and reactive maintenance.
Building and Guest Room Management Systems interface
The Vari PRO room controller can also be controlled via building automation system. The set point temperature can be controlled both from building automation system and from guest room management system based on the occupancy or other needs.
