Raypak B6000 - Manual (Page 2)

Efficient Flame
Modulation
A key element in
reducing energy costs
and in total system
comfort is the ability
of a boiler to precisely
meet the heating load.
Raypak not only
pioneered modulating
technology for copper
finned tube boilers,
Raypak perfected it.
Fuel input is evenly
and accurately throttled to as low as 20% of boiler full fire rate to track any load
requirement. Two Raypak modulating boilers will throttle to 10% of the full fire
rate. Wasteful short cycling is eliminated, greatly improving operating efficiency.

1.
This status display gives the
u s e r t h e c u r re n t o u t d o o r
temperature, the current water
temperature, and the calculated
target temperature.
2.
This display gives the operational
status of each boiler. In the event of
a fault, its origin is displayed, a red
LED indicator light flashes, and an
alarm will sound at the System
Controller. A red LED indicator light
on the Boiler Monitor will also light
up.
3.
The user can set the optimum
temperature set point, outdoor
reset ratio, throttling range, and
control band based on system
design and outdoor conditions.
4.
The user selects the lead boiler in
a multi-boiler system.
Sequencing can also be
programmed automatically
with the optional Selecset™.
5.
The user can select an
energy-saving pump delay of one to
ten minutes. The selectable
ignition time feature determines the
length of time the pilot will spark
without main burner ignition before
a fault condition is noted.
6.
Selecset™ option allows the
operator to program setback times.
UL listed Energy Management

shielded communication cable to
each boiler monitor and a two-wire
shielded cable to each sensor.
Provides remote programming and
status evaluation
Diagnostic annunciation at boiler
and at remote-mounted system
control. Continuous monitoring of
up to 15 boiler operating
parameters. Audible alarm at
system control.
Controls up to 8 boilers
Applicable to all major codes
Displays temperature in Fahrenheit
or Centigrade
Default values represent standard
operating conditions for most
systems.
T
he B6000 system control has up to fifteen separate displays that have the capability to give system status or allow the user to program new data. Here are examples of six:

system.
• T-3
Modbus interface for use with
Honeywell™, Landis & Staefa™ and
other Modbus energy management
systems.
• T-10
Selecset™ (night setback) reduces
system temperature during up to six
off-peak periods each day. This
feature also allows for lead-lag
programming when using multiple
boilers.
T
