CHAPTER 8 - EXTERNAL WIRING
8.1. General Requirements
All field wiring must comply with:
• National Electrical Code (ANSI/NFPA 70) for installa-
tions in the U.S., and any other national, state, pro-
vincial or local codes or requirements.
• Canadian Electrical Code Part 1 (CSA C22.1) for in-
stallations in Canada.
ELECTRICAL SHOCK HAZARD. For your safety,
disconnect electrical power supply to the unit
before servicing or making any electrical con-
nections to avoid possible electric shock hazard.
Failure to do so can cause serious injury, or death.
The low voltage terminals are located at the
bottom of the ACVMax control module. The
line voltage terminals are located in the lower
right corner as shown in Fig. 21 below.
8.2. Line Voltage Connections
1. Connect a dedicated 120 VAC/15A service to the
line voltage terminals located internally in the low-
er right corner, as shown in Fig. 21 below.
2. Route the incoming 120 VAC power wires through one
of the provided openings in the bottom 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 require an additional service
switch, the installer must provide and install a fused
disconnect or minimum 15 amp service switch.

8.3. Circulator Wiring
1. The circulator connections used will depend on
the systems piping layout. See
Fig. 9 on page 18
through Fig. 12 on page 21
for common system
piping applications and associated circulator wir-
ing. Consult the PRESTIGE ACVMax Control Supple-
ment for additional options.
The circulator, flame, and alarm outputs are
protected by fuses on the ACVMax control
module. The total combined amp draw of the
CH, DHW, and Flame outputs must not exceed
4 amps at any time for the Solo 80 through
250, or 3 amps at any time for the Solo 299 &
399. The total combined amp draw of the P3,
P4, and Alarm outputs must not exceed 5 amps
at any time for all Prestige models. Use an iso-
lation relay to lower the total combined amp
draw if exceeding this limits.
2. Connect the CH circulator wiring to the line voltage
terminals located internally in the lower right corner, as
shown in Fig. 21 on the left . This circulator is typically
used to supply heat to the central/space heating loop.
3. Connect the DHW circulator wiring to the line volt-
age terminals located internally in the lower right
corner, as shown in Fig. 21 on the left . This circulator
is typically used to supply heat to an indirect hot
water heater.
4. Connect the P3 circulator wiring to the line voltage
terminals located internally in the lower right cor-
ner, as shown in Fig. 21 on the left . This circulator is
typically used to circulate water through the PRES-
TIGE Solo in primary/secondary piped systems.
5. Connect the P4 circulator wiring to the line voltage termi-
nals located internally in the lower right corner, as shown
in
Fig. 21 on the left
. This circulator is typically used as a
dedicated circulator to a second space heating zone.
8.4. Flame Status & Alarm Wiring
The Flame and Alarm outputs both supply
110VAC when activated. Use an isolation relay
to provide dry contacts if required by the exter-
nal monitoring system.
The Flame output is typically used to provide on/off sta-
tus to an external monitoring system. The Flame out-
put will provide 0VAC when the PRESTIGE Solo is not
fired and 110VAC when the PRESTIGE Solo is fired.
