cascade Installation – cascade communication cable
• A communication cable PTCAB01 must be installed between each
boiler in the Cascade System. The cable has a 6 pin molex connec-
tor on one end and bare wires on the other end. The molex connec-
tor plugs into the Cascade Slave connector of the Slave boiler. The
bare wires terminate on the Cascade Master terminals of the Master
boiler or prior Slave boiler in cascades of three or more boilers.
Reference Figure 7,9,11 on pages 27, 29, 31 for wiring details. The
connections are as follows:
Red Wire to Terminal #17
White Wire to Terminal #18
Black Wire & Cable Shielding to Terminal #19
cascade Installation – Low Voltage Wiring connections
• Thermostat Wiring – CH1 and CH2 calls must be wired into the
Cascade Master.
• Outdoor Sensor Wiring – The outdoor temperature sensor must be
wired into the Cascade Master.
• Domestic Hot Water Wiring – A DHW call must be wired into the
Cascade Master.
• Additional Boiler Limits – Boiler Limits must be wired into each
boiler in the Cascade System. When a boiler limit opens, that par-
ticular boiler will lockout and will be removed from Cascade System
operation. The other boilers in the Cascade System will continue to
operate if they are not in a lockout.
• External Modulation Control – An External Modulation Signal must be
wired into the Cascade Master. The modulation signal will control the
firing rate of the entire Cascade System, not just the Cascade Master.
• Modbus Wiring – A building management system (BMS) connection
must be wired into the Cascade Master.
cascade Installation – Line Voltage Wiring connections
• Circulator Wiring - Reference Figures 7,9, 11 on pages 27, 29, 31 for
circulator wiring required for each type of Cascade System. The cir-
culator connections used will depend on the systems piping layout.
Each circulator is individually fused with a 2.5a fuse located in the ter-
minal strip. The total combined amp draw of the cH (1), dHW, and
auxiliary Boiler circulators must not exceed 4 amps at any time for the
PRESTIGE Solo 60, 110, 175, or 250. The total combined amp draw of
the cH (1), dHW, and auxiliary Boiler circulators must not exceed 3
amps at any time for the PRESTIGE Solo 399. Use an isolation relay to
lower the total combined amp draw if exceeding these limits.
