Installation Compliance
All field wiring made during installation must
comply with:
- National Electrical Code NFPA 70 and
any other national, state, provincial or
local codes or requirements.
- In Canada, CSA C22.1 Canadian Electrical
Code Part 1, and any other local codes.
ELECTRICAL SHOCK HAZARD.
Before making any electrical connec-
tions to the PRESTIGE, disconnect elec-
trical power supply at the service panel.
Failure to comply can cause severe per-
sonal injury or death.
The line voltage terminals are located on
the right set of terminals 23 through 40.
The low voltage terminals are located on
the left set of terminals 1 through 22.
Line Voltage Connections
1. Connect a dedicated 120 VAC/15A service
to the line voltage terminal strip on the
wiring panel below the PRESTIGE control
module, as shown in Fig. 19, page 29.
2. Route the incoming 120 VAC power wire
through the provided openings in the bot-
tom jacket panel.
3. The unit is provided with a service switch
located on the front panel, check local code
requirements for compliance.
If local electrical codes or conditions
require an additional service switch, the
installer must provide and install a fused
disconnect or 15 amp (minimum) service
switch.
Circulator & Diverter Valve Wiring
The PRESTIGE Excellence contains a
prewired Boiler circulator as well as a Diverter
Valve. The Boiler circulator is enabled for any
CH1, CH2, or DHW call. The Diverter Valve
will direct water flow to the CH Supply
Connection at the bottom of the boiler during a
CH1 or CH2 call or to the internal Indirect
Water Heater during a DHW call.
1. The Boiler circulator is prewired to the line
voltage terminal strip on the wiring panel
below the PRESTIGE control module, as
shown in Fig. 19 on page 29. The Boiler
circulator is enabled for any CH1, CH2, or
DHW call. This circulators is used to sup-
ply heat to the central/space heating loop as
well as the internal Indirect Water Heater.
2. The Diverter Valve is prewired to the line
voltage terminal strip on the wiring panel
below the PRESTIGE control module, as
shown in Fig. 19 on page 29. The Diverter
Valve will direct water flow to the CH
Supply Connection at the bottom of the
boiler during a CH1 or CH2 call or to the
internal Indirect Water Heater during a
DHW call.
3. Connect the System circulator to the line
voltage terminal strip on the wiring panel
below the PRESTIGE control module, as
shown in Fig. 19 on page 29. The System
circulator is enabled during a CH1 or CH2
call with the factory default Trimax
Settings. This circulator is typically used to
circulate water in the secondary CH loop
when zoning with zone valves.
Each circulator/diverter valve output is
individually fused with a 2.5A fuse locat-
ed in the terminal strip. Use an isolation
relay if the circulator amp draw exceeds
2.5A.
