Models range from 500,000 BTU to 6 million BTU and all models are available in non-condensing, near-condensing or fully condensing modes along with a primary heat exchanger made of stainless steel or copper/cu-ni.

Some standard features include a flow switch, pressure relief valve, low gas pressure switch and flame failure contacts.
The system 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 easy control also includes 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.

Boilers are equipped with standard Modbus RTU communication protocol to allow for BMS access to 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.

Additionally, this model is available with BacnetIP, BacnetMSTP, LonWorks and MetasysN2 protocol support. All the features available in the Modbus RTU realm are carried into these protocols with the use of 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 indicates a high quality product with maximum performance and ease of connectivity.
