BMC and BMC-6X Installation and Operation Manual
System Run-On
•
This feature lets the BMC run the SYS relay for a longer period after the boilers have been turned off. When this relay is used to
control a pump, it helps in dissipating the excess heat from the boilers combustion chamber.
Each of the BMC or BMC-6X consists of three primary enclosure components.
•
The Enclosure Display Module: contains the display, buttons, LEDs and electric wiring terminals. It has two screws to hold it
to the base. A program configuration switch, used to adjust BMC settings, is placed above the terminals. This switch is enclosed
with the enclosure wiring cover for security. Wiring terminals are of the plug-in type to ease installation and removal.
The Enclosure Base: contains the holes to mount and hold the control against the wall or any flat surface. All other enclosure
•
components mount on the base. The bottom section of the Enclosure Base contains the wiring chamber with knockouts on the
bottom to easy installation.
The Enclosure Wiring Cover: seals the wires from the external environment. It has two screws to hold it the base and a hole to
•
secure a lock on the wiring enclosure. A plastic web that separates the wiring chamber into high and low volt sections has been
provided.
MOUNTING THE ENCLOSURE
•
Select a location near the equipment to be controlled.
•
The surface should be flat and sufficiently wide and strong to hold the BMC
or BMC-6X.
•
Keep the control away from extreme heat, cold, or humidity. Ambient
operating temperature is from 20 to 120°F.
•
Remove the Enclosure Wiring Cover from the control enclosure by
removing the two bottom screws.
•
Remove the Enclosure Display Module by removing the middle screws.
•
Screw the Enclosure Base to the surface through the upper and lower
mounting holes on the back of the enclosure.
•
Replace the Enclosure Display Module and replace the middle screws.
•
Do not replace the enclosure wiring cover until all wiring is done.
•
When purchasing a padlock for the enclosure, the maximum shank diameter
should not exceed ¼"
