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

Using a smart algorithm, the BCP-8W can monitor the boiler return temperature using an optional return sensor mounted on the return

Having a DHW input either as a dry contact to be used with an external aquastat or as a temperature sensor that can be ordered separately,
the BCP-8W can control a DHW pump using its built-in DHW Pump output relay. The user will have different priority options that
varies based on the DHW piping design.

In Outdoor Reset, the BCP-8W controls a hot water heating system to provide a building with
comfortable and even heat levels. The BCP-8W varies the Target temperature of the circulating
heating water in response to changes in the outdoor temperature.
The BCP-8W also controls the system circulating pump with an adjustable Outdoor Cutoff.
When the outdoor temperature is above the Outdoor Cutoff, the System Pump will be off
and no heating water is circulated through the system. When the outdoor temperature drops

The BCP-8W has multiple operating modes that satisfy most hydronic systems. When the
Outdoor Reset is selected, it can change the System Set Point based on outdoor temperature.
Or, it can be set to Set Point and sequence stages to achieve a manually adjusted Set Point.

A heating curve that relies not only on Outdoor temperature but also on the type of
radiation will improve heat comfort. The following are suggested initial settings for
different types of radiation based on average building insulation and heat loss. The

Water Temperature
Reset Ratio Curves
When a building is being heated, heat escapes through the walls, doors, and windows to
the colder outside air. The colder the outside temperature, the more heat escapes. If you
can input heat into the building at the same rate that it is lost out of the building, then the
building temperatures will remain constant. The Reset Ratio is an adjustment that lets
you achieve this equilibrium between heat input and heat loss.

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

the new calculated set point based with the Offset should be 175°F. However, it will not
exceed 170°F due to the Maximum Target setting.
,IUHTXLUHG$GMXVWWKH:DWHU2IIVHWLQPLOGZHDWKHU. If the ambient building
temperatures are too warm in the mild weather, decrease the Target Offset. If the
ambient building temperatures are too cold in the mild weather, increase the Target
Offset. The rule of thumb for baseboard radiation is to change the Offset 4°F for every
1°F you wish to change the building temperatures. In radiant heat applications, change
the Offset 1°F or 2°F for every 1°F you wish to change the building temperature.

The BCP-8W will control the boiler’s operation to maintain the desired Set Point. Only boilers set to Auto can be lead
boiler.
These boilers can only be activated when all boilers in Auto have been at HI for an adjustable Standby delay period.
Standby boilers are generally used as a backup in extreme load conditions. Note that, a Standby boiler cannot be a lead
boiler. Standby Delay is only available in PID mode.
Any output boiler not connected to a physical boiler should be set to Off. The Off Mode can also be used to disable
boilers that are being serviced.
The On Mode should only be used when testing a boiler. The On Mode overrides the PROVE and SHUTDOWN inputs.
Once set to On the boiler will immediately start all of its stages.

‡ 5HDFWLRQ7LPHDQG0LQLPXP5XQWLPH- If the system is overshooting or undershooting,
adjust Minimum Runtime or the Reaction Time. That depends on if the stages are brought on
fast and were not allowed to turn off until the Minimum Runtime elapsed. Or, the stages were
brought on slowly, however, were allowed to turn off quickly.
‡ 3,'YV266- If the application the system is used on requires fast response that the normal
PID mode cannot provide, try using the OSS mode and adjust the Throttle Range according to
the system requirements.
