The BMC is the perfect control whenever multiple fully modulating stages are required for hydronic heating applications. The BM C controls the on/off and the modulation of each stage to maintain precise system set point control.
5 BMC and BMC-6X Installation and Operation Manual UNDERST ANDING OPERA TION CONCEPT The BMC has multiple operating modes that satisfy most hydronic systems. It can change the System Set Point based on outdoor temperature (Outdoor Reset) or it can modulate its stages to achieve an adjustable fixed Set Point.
6 BMC and BMC-6X Installation and Operation Manual MAKE SURE YOU HA VE THE RIGHT CONTROL If you need the BCP-8W to do additional tasks that either are not listed or do not know how to set them, contact W eil McLain.
7 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 .
8 BMC and BMC-6X Installation and Operation Manual INST ALL THE SENSORS HEA TING SYSTEM SENSOR (HSS) INST ALLA TION LOCA TING HSS • Put the Heating System sensor approximately 10' feet past the last boiler on the common supply header but before any major takeoffs.
9 BMC and BMC-6X Installation and Operation Manual WIRING WIRING THE POWER (TERMINALS 1, 2) • Bring the 120V AC 60Hz power wires through the bottom Knockout of the enclosure. • Class 1 voltages must enter the enclosure through a different opening from any Class 2 voltage wiring.
10 BMC and BMC-6X Installation and Operation Manual WIRING THE PROVE (TERMINALS 29, 30) • The Prove feature is provided to check system component operation and must be selected in the Startup Menu. See page 15. • A typical use of this feature is to check for pump flow before firing any boiler .
11 BMC and BMC-6X Installation and Operation Manual WIRING TO MODULA TING MOTORS The BMC can modulate any combination of the following motors. The Output T ype must be selected properly before connecting any output wires to avoid damage components. See Output T ype on page 1 1.

17 BMC and BMC-6X Installation and Operation Manual OPERA TING SETTINGS PROGRAM CHANGE SETTINGS T o be able to change the BMC settings the Program/Run Switch must be set to Program. The switch is located under the Enclosure W iring Cover for security .
18 BMC and BMC-6X Installation and Operation Manual OUTDOOR CUTOFF TEMPERA TURE Adjustable Off, from 20 º F/ to70 º C - 100 º F , On Default: 60ºF/ 16 º C Button: MENU/Set Point/Outdoor Cutoff in.
19 BMC and BMC-6X Installation and Operation Manual SYSTEM SETTINGS Button: MENU/<System Settings> The Settings 1 and Settings 2 menus provide access to adjusting and fine-tuning the system for enhanced comfort and more fuel savings. The BMC behaves dif ferently based on the selected Control Modes (see Startup Settings).
20 BMC and BMC-6X Installation and Operation Manual LAG DELA Y Adjustable from 0min to 60min Default: 0min Button: MENU/<System Settings>/Lag Delay • The Lag Delay requires the previous stage to remain at 100% modulation for the full period of the Lag Delay before another Stage can be activated.
21 BMC and BMC-6X Installation and Operation Manual • If Setback Input is selected as a Shutdown/T stat/Setback Mode (See page 15), the Setback will not be activated unless a Short dry contact signal is received on the Shutdown/T stat/Setback terminals ( 31 and 32 ) as a signal.
22 BMC and BMC-6X Installation and Operation Manual SET TIME Button: MENU/<System Settings>/<Mor e Settings>/Set T ime Button: MENU/<System Settings>/<Mor e Settings>/<Day/Night Schedules>/Set T ime • Adjust the time by selecting T ime from the menu and then scrolling through the hours then select Save.
23 BMC and BMC-6X Installation and Operation Manual MAINTENANCE Button: MENU/<Maintenance> The Maintenance menu gives access to sensor and outputs trimming and Soft-Off. In addition, you'll have access to view the Startup configuration settings.
24 BMC and BMC-6X Installation and Operation Manual CONFIGURA TION Button: MENU/<Maintenance>/<Configuration> • This menu option provides a consolidated view of the BMC's Startup and Stage settings. BACK NEXT ------ CONFIGURATION 1 ------ v1.
25 BMC and BMC-6X Installation and Operation Manual DISPLA Y MESSAGES The BMC normal display layout reserved the second line for message indications. The following is a list of the most common Message Display Line information: • Summer The control is set to Summer .
26 BMC and BMC-6X Installation and Operation Manual Auto - The BMC will control the boiler ’ s operation to maintain the desired Set Point. Only boilers set to Auto can be Lead boilers. Standby Standby boilers can only be activated when all boilers in Auto have been at 100% modulation for a selectable period of time.
27 BMC and BMC-6X Installation and Operation Manual TROUBLESHOOTING SENSOR INPUTS Display shows Sensor OPEN or SHORT When OPEN, Check the sensor is connected and the wires are continuous to the BMC. Finally follow the procedure for Incorrect T emperature or Pressure Display .
28 BMC and BMC-6X Installation and Operation Manual • Boiler Mode Settings - The BMC will only modulate boilers their mode is set to Auto or Standby . Check if any boiler stage is set to Manual, Off, or Standby . See Mode on page 25. Boilers are Short-Cycling • Lag Delay - Increase the Lag Delay only if all boilers tend to short-cycle.
