The BCP-8S’s control PID algorithm allows it to look at the rate of change in the system. If the system oscillation is minimal, the BCP-
8S will make slow and gradual output adjustments. If the load is changing quickly, the BCP-8S can be set to OSS sequencing where it
will react based on load changes. 7KHUHIRUHꢀꢁWKHꢁ%&3ꢂꢃ6ꢁDGDSWVꢁWRꢁVSHFL¿FꢁV\VWHPꢁUHTXLUHPHQWVꢁDQGꢁPLQLPL]HVꢁRVFLOODWLRQꢁDURXQGꢁWKHꢁ

Rotating the lead stage on a call for output promotes even wear on each boiler. The BCP-8S has three modes of rotation: Manual, FOFO
(First-On/First-Off), or Time. The Time option rotates the lead stage every selected period, from every hour to every 41 days.

As a stand-alone, the BCP-8S is designed to control eight stages. However, it has the capability of expanding its control to two BCP-8X
extension panels each with eight stages. Thus, the BCP-8S can control a total of up to 24 stages.

Regardless of the type of applications, Setback is an energy saving feature. The BCP-8S offers a built-in day/night schedule for the
setback period. On the other hand, if external scheduling is to be used, the Setback can be activated using an external signal by shorting
the SETBACK input terminals.

The BCP-8S has multiple operating modes that satisfy most steam systems. It can sequence stages to achieve an adjustable Set Point.
Moreover, when used with the 420MOD Interface (389-900-226) it can accept a 4-20mA signal as a set point. The 420MOD must be
purchased separately. This gives the BCP-8S the capability of being controlled remotely.

The BCP-8S will control the unit’s operation to maintain the desired Set Point. Only units set to Auto can be lead unit.
These units can only be activated when all units in Auto have been at HI for an adjustable Standby delay period.
Standby units are generally used as a backup in extreme load conditions. Note that, a Standby unit cannot be a lead
unit. Standby Delay is only available in PID mode.

Any output unit not connected to a physical unit should be set to Off. The Off Mode can also be used to disable units
that are being serviced.
The On Mode should only be used when testing a unit. The On Mode overrides the PROVE and SHUTDOWN inputs.
Once set to On the unit will immediately start all of its stages.
