WARNING
All wiring and grounding must be done in accordance with the authority having jurisdiction or, in the absence of
such requirements, with the National Electrical Code (ANSI/NFPA 70).
VII. Wiring
This manual covers wiring the Bimini Buddy into BWC series boilers using having two different control systems:
Control Systems using Honeywell Type III MCBA • - This control system has been used on all BWC series
boilers manufactured between 2005 and late 2010. It uses an LED display.
Control Systems using Honeywell Sola • - This control system is being phased in during 2010 and is
distinguished by a Panasonic touch screen display.
Connecting BB100H to Type III MCBA Equipped boilers (Figure 7.0): 1)
Connect the boiler circulator to the red lead and neutral (white) in the Boiler’s J-Box. If the system has a single a.
system circulator, and the total combined current draw of the boiler and system circulators is less than 2.0A, the
system circulator can be wired in parallel to the boiler circulator. Otherwise, a relay (shown) or zoning panel
must be used to operate the system pump.
Connect the heating thermostat, or zoning panel boiler contacts, to terminals 1&2 on the boiler. b.
Connecting BB100H to Sola Equipped boilers (Figure 7.1): 2)
Connect the boiler circulator to the terminals marked “BLR Pump” in the boiler’s J-Box. a.
Connect the system circulator to the terminals marked “Sys Pump” in the boiler’s J-Box. b.
Connect the heating thermostat, or zoning panel boiler contacts, to the “CH Stat” terminals on the left side of c.
the boiler’s control compartment.
Connecting BB100I to Type III MCBA Equipped boilers (Figure 7.2): 3)
Connect the boiler circulator hot to the red lead and neutral (white) in the Boiler’s J-Box. a.
Connect the three way zone valve in the BB100I to the blue lead and neutral (white) in the boiler’s J-box. If b.
the system has a single system circulator having a draw of less than 1.5A, the system circulator can be wired in
parallel with the zone valve (after reprogramming the MCBA per part G of this manual, the zone valve will be
powered during a call for heat). Otherwise, a relay or zoning panel must be used to operate the system pump.
The heating thermostat, or zoning panel boiler contacts, are connected to terminals 1&2 on the boiler. c.
The indirect water heater’s thermostat is connected to terminals 7&8 on the boiler. IWH thermostat contacts d.
must be “dry”.
Connecting BB100I to Sola Equipped boilers (Figure 7.3): 4)
Connect the boiler circulator to the terminals marked “BLR Pump” in the boiler’s J-Box. a.
Connect the three way zone valve in the BB100I to the terminals marked “DHW Pump” in the boiler’s J-Box. b.
Connect the system circulator to the terminals marked “Sys Pump” in the boiler’s J-Box. c.
Connect the heating thermostat, or zoning panel boiler contacts, to the “CH Stat” terminals on the left side of d.
the boiler’s control compartment.
Connect the indirect water heater’s thermostat to “DHW Stat” terminals on the left side of the boiler’s control e.
compartment.
