This model consists of a two-pass counter flow fire tube commercial boiler which is used for hydronic heating and hot water supply. Features include thermal efficiencies of up to 99% and turndown ratios of up to 25:1. Standard features include a flow switch, pressure relief valve, a low gas pressure switch and flame failure contacts.

This model is controlled by an integrated Honeywell SOLA controller. The 7” color touch screen is designed for remote operation through the 4-20mA or 0-10Vdc for set point or fire rate control. When combined with the ability to control multiple pump operations 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.

All models are equipped with standard Modbus RTU communication protocol allowing for for BMS access to view boiler operation. The remote monitoring of a boiler plant enables 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. This model is available with BacnetIP, BacnetMSTP, MetasysN2 and LonWorks protocol support.  All the features available in the Modbus RTU realm are carried into these protocols with the use of a highly advanced yet easy to use 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 optimum performance and ease of connectivity.
