Mounting and Wiring AM-4 Module
Electrical Shock Hazard. Turn off the power
to the boiler before proceeding with the
installation of the AM-4 module. Failure to
comply could result in severe personal injury,
death, or substantial property damage.
1. Remove the front panel of the Prestige by
removing the mounting screws along the upper
edge of the unit. Lift the panel up and pull for-
ward to remove the front panel from the unit.
2. Remove the screw retaining the control panel.
Open the display panel cover and swing the
control panel out.
3. Insert a small flat-blade screwdriver into slot on
the bottom of the AM-4 module near the tapered
end of the module and gently pry off the cover.
Use care not to damage the cover or the module.
4. With the AM-4 cover removed and facing the
electronics orient the AM4 with the ribbon
cable connection toward the top. Insert the rib-
bon cable according to the keyed connector and
the red strip on the right. Route the ribbon cable
through the top cutout of the control cover.
5. Route the wires from the Multiple Boiler
Controller 0 –10v terminals and any optional
alarm wires through the wire ways of the
Prestige boiler and along the Prestige factory
wiring. Strip the wire ends and connect to the
AM-4 terminals X2-1 and X2-2 for the 0-10 vdc
analog signal and X1-1 and X1-2 for the alarm
as shown in Figure 1. Use the cable clamps pro-
vided in the AM-4 kit to secure the incoming
wires to the module.
Ensure the polarity of the wire connections
from the Boiler Controller to the AM-4 is
maintained as shown in Figure 1. Failure to
maintain polarity will cause the AM-4 to
receive erratic and/or no signal from the
Boiler Controller
6. Snap the cover back on the AM-4 module.
7. Place the AM-4 on the backside of the control
panel as shown in Figure 2 on page 3. Align the
mounting holes of the AM-4 with upper or lower
clearance holes along the hinged side of the con-
trol panel. Secure the AM-4 module using the
two screws provided in the AM-4 kit, from the
front of the control panel as shown in Figure 2 on
page 3.
8. Insert the ribbon cable according to the keyed con-
nector into the empty socket of the Prestige MCBA
control module. The red strip on the ribbon cable
should be positioned toward the top or left side
depending upon MCBA control orientation.
