Burnham Sage2.1 Boiler Control System (SBC2.1) - Overview

The Burnham Sage2.1 boiler control system is the next

generation of advanced electronic controls designed

specifically for condensing boilers by U.S. Boiler

Company in partnership with Honeywell. The Sage2.1 is

currently installed on Burnham Alpine condensing boilers

and will be incorporated into additional condensing

boilers in the future.

The Sage2.1 was designed with many features that

make the control simple to understand and use, as well

as features that optimize boiler performance, flexibility

and overall system efficiency and reliability. The

Sage2.1 builds on the impressive list of standard

features that were provided with the original Sage2 control system. Additional features

incorporated into the Sage2.1 system now allow multiple Sage2.1 equipped boilers to be

connected with simple RJ45 Ethernet cables and staged from an internal sequencer. All the

features on the Sage2.1 control system make boiler installations more competitive and

easier to install and set up in the field. The Sage2.1 boiler control system is simply the

most powerful, versatile, and installer-friendly boiler control available and it is only available

on Burnham brand products. Here are the key features of this exciting new control system:

• Touch Screen LCD Display: Every boiler equipped with the Sage2.1 boiler control

will include a built-in LCD touch screen control. Boiler status, settings, and diagnostic

information are all accessible from the display in simple English text. Control settings can

be adjusted from the display, and advanced settings are protected with two levels of

password protection to prevent advanced settings from being adjusted by unauthorized

users. Built-in diagnostics allow simple trouble-shooting of the boiler. In the event of an

error or lockout, the Sage2.1 display turns red. Blinking buttons guide the user through

diagnostic screens that explain the issue and how to resolve or repair the issue. Help

screens are provided, offering detailed explanations of each setting in simple terms that are

easy to understand. The Sage2.1 is intuitive, and guides the user through the settings.

This reduces the amount of time spent on the job scanning through control manuals, and

gets the installer off the job quicker with fewer issues.

• Control Data Logging: The Sage2.1 can display and recall information from

numerous control parameters. The previous five (5) lock-out events can be recalled on the

display. Real time trending tracks the following four parameters: Supply Temperature,

Return Temperature, Flame Signal, and Boiler Firing Rate in a running graphic display. The

control also logs runtime hours for the boiler as well as the number of cycles for the boiler,

the boiler pump, the DHW pump, and the system pump. This information can assist in

diagnosing both boiler and system issues, saving valuable time on service calls.

Burnham Sage2.1 Boiler Control System (SBC2.1) – Overview (con’t) • Outdoor Reset: The Sage2.1 control features a built-in outdoor reset control which adjusts boiler temperature based on the outdoor temperature. During warmer temperatures the building requires less heat, and the boiler temperature is reduced. This feature helps to keep the boiler in condensing mode longer, resulting in higher efficiency.

Burnham Sage2.1 Boiler Control System (SBC2.1) – Overview (con’t) • Freeze Protection: If possible freezing water temperatures are detected, the Sage2.1 will operate all pumps connected to the boiler. If water temperatures continue to drop, the boiler will operate and heat the system slightly in order to prevent freezing and damage to the system. • Pump Exercise: If a circulator that is connected to the Sage2.1 control does not operate for seven (7) days, it is activated to run for twenty (20) seconds.

The call for heat, outdoor and header sensors, and pumps are wired to the master enabled Sage2.1 Controller. - Multiple Firing Rate Sensor Options: The Sage2.1 has multiple firing rate sensor options.

Stand-Alone Back-up: If the Master Sage 2.1 Control is powered down, disabled, or loses communication with connected boilers, individual boilers can be connected to resume control as stand alone boilers. 3. Slave Boiler Rate Adjustment: Each slave boiler continues to monitor supply, return, and flue gas temperatures and modifies the Sequence Master’s firing rate demand to help (a.) avoid individual boiler faults, (b.

When selected, the Sage2.1 control system accepts 4-20mA remote setpoint or firing rate demand signals from an external BAS/BMS. External controls can modulate the Alpine’s firing rate in order to satisfy overall system demand.

This ensures the boiler will modulate properly in the event that the manual firing rate mode is not disabled to the “off” status after testing. o Sage2.
