Control Panel Highlights

The Advantus™ is controlled by an integrated Honeywell SOLA controller. The 7” color touch screen provides remote operation through the 4-20mA or 0-10Vdc for set point or fire rate control. Paired with the ability to control multiple pump operation along with daisy chain set up for up to 8 boilers, this user friendly control also provides you with a USB output for screenshot capture, as well as password access for service personnel.  Up to 8 SOLA devices may be monitored and controlled with one single display. 


In a world where we are becoming more connected, the Advantus™ is ready to enter this revolutionary phase in building automation. All Advantus™ are equipped with standard Modbus RTU communication protocol to allow for BMS access to view boiler operation. The remote monitoring of a boiler plant allows for complete overview of various boiler-related temperatures, boiler status, pump activation, boiler error codes and more. This is not just limited to read-only parameters, as a BMS is permitted to write setpoint temperatures, enable/disable and remotely send and receive firing rate requests. To further evolve and adapt to the changing marketplace, the Advantus™ is available with BacnetIP, BacnetMSTP, MetasysN2 and LonWorks protocol support.  All the features available in the Modbus RTU realm are carried into these protocol’s with the use a highly advanced yet user friendly Fieldserver Protonode. The Fieldserver Protonode is equipped with Ethernet or RS485 connectivity and is BTL (BACnet Testing Laboratory) Certified. This approval assures that we carry only the highest quality products with optimum performance and utmost ease of connectivity.
