Boiler Management

Systems

The HeatNet boiler control is designed to provide RBI Fusion

and Futera Series (III & XLF) boilers with an integrated boiler

management system. HeatNet systems provide precise system

control, repeatability and feedback thru digital communication.

The control monitors boiler temperatures and limit circuit

inputs to maximize turndown ratios to maintain peak efﬁ ciency

through 5 temperature setting inputs: outside air, outlet (supply)

water temperature, inlet (return) water temperature, header

temperature and boiler stack temperature.

HeatNet is capable of operating RBI units as single boilers,

multi-boiler Master/Member networks of up to 16 boilers and

also boiler units connected to independent Building Management

Systems. Using the HeatNet integrated boiler management

system virtually eliminates wall-mounted control panels and

offers easy to read displays with intuitive control menus.

The control conﬁ guration “learns” the applications optimal

ﬁ ring rates by using microprocessor electronics to monitor time-

average responses based on actual usage to determine the load

for the system for optimal energy efﬁ ciency. Standard HeatNet

controls use a Modbus protocol with optional protocessor boards

for BACnet and LonWorks based building management systems.

Variable control settings for Mod/Max ﬁ ring rates allow

adjustable maximum ﬁ ring rates enabling all boilers to run at

extremely efﬁ cient levels until all units in the sequence have

ﬁ red at which time ﬁ ring rates can increase above the standard

setting to meet system demands. Boiler ﬁ ring rotations can

be programmed for ﬁ rst on/ﬁ rst off, ﬁ rst on/last off or “True

Rotation” which rotates boiler run-times so that all units run for

the same amount of time.

Electronics are located in a self-contained control enclosure

through which all internal components and terminal blocks are

easily accessed via a hinged, swing open door panel on the front

of all units.
