• External Multiple Boiler Control Compatible: The Sage2.1 control can
be connected to external staging controls and accepts 4-20mA and contact inputs
from a multiple boiler controller. 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. No additional relays or wiring is required.
• Energy Management System (EMS) Compatible: The Sage2.1 control can be
connected to a building’s energy management system (EMS) using simple menu selections
and wiring a 4-20m Adc input. The Sage2.1 allows EMS controls to adjust either the central
heating setpoint or the firing rate of the boiler. This allows the Sage2.1 to be compatible
with EMS controls that develop energy efficient setpoints based on outside air temperature,
solar loading, and actual room air temperatures. The Sage2.1 uses this setpoint input to
cycle the boiler and modulate the boiler’s firing rate.
• “Night Setback” and “Unoccupied” Control Modes: The Sage2.1 is
EnviraCom
™
enabled, allowing the boiler to communicate directly with Honeywell
EnviraCom
™
thermostats. This feature allows the boiler to further enhance system
efficiency by reducing the water temperature during home “sleep” and “away” modes.
• Reliability: The Sage2.1 has been designed to have the best boiler control reliability
and durability available in the industry today. Many of the industry’s most common boiler
control issues have been factored in to the design of the Sage2.1. For example, the
Sage2.1 features built-in brown-out protection. If the power supply temporarily dips in
voltage - a symptom known as a “brown-out”, the Sage2.1 will re-cycle when voltage
recovers, continuing to heat the building without requiring a service call to manually reset
the control. In addition, no additional devices such as “brown out relays” are required for
the boiler. The Sage2.1 features duty rated pump relays and wiring, meaning the control
also may not require internal fuse protection for pump outputs if the total amp draw does
not exceed the circuit breaker rating. The control is capable of handling up to 15 amps,
and will not require additional relays to switch power to the circulators in most installations.
• Simple and Easy Operation: The
Sage2.1 boiler control is simple, intuitive, and
easy to operate. The straightforward full text
display shows the settings and status of the
boiler is user-friendly, saving the installer time.
The Sage2.1 LCD option provides expanded
factory diagnostic screens providing additional
information and troubleshooting assistance.
The Sage2.1 control does not require special
tools such as handheld electronics, or PC’s with
expensive software and adapters to interface
with the boiler in order to make adjustments or
access operating information.
