BSC Installation and Operation Manual
Sequences up to 4 Fully Modulating Stages
The BSC is the perfect control whenever multiple fully modulating stages are required for heating or cooling applications. The BSC
controls the modulation of each stage to maintain precise set point control.
PID Type Logic
The BSC's control algorithm allows it to look at the rate of change in the system. If the system temperature/pressure is changing
quickly, the BSC will react quickly to adjust the stages' modulating output. If the system temperature/pressure changes slowly, the
around the set point.
Controls 0-5V, 0-10V, 1-5V, 2-10V, 4-20 mA, or 0-135 modulating motors
The BSC is designed to accurately control the output from 0 to 100% of modulation for each of these different types of motors. One
BSC can even control two different types of motors.
Process or Normal Applications
The BSC controls the stages based on the type of logic selected. It offers a Normal (PID) logic for slow responding systems. This
option is useful in heating applications where In addition, it offers a Process option for systems that requires fast response.
Digital Display of all System Settings
The BSC's 80 character alphanumeric digital display names each system parameter in plain English and shows its precise value. The
Automatic Rotation among Stages
Manual, Last-On, or Automatic every selected time period from every hour to every 41 days.
Outdoor Reset Control
The BSC has a stand-alone hydronic outdoor temperature reset function (When Sensor Type is set to Reset °F or Reset °C.). This
allows it to change the target set point based on outdoor temperature changes.
Connects to Energy Management Systems
BSCs can accept a 4-20 mA input signal from an EMS to adjust the temperature set point remotely. In addition, an Energy
Management System (EMS) or other controller can disable the BSC when there is no output requirement.
Monitors Stage Status
The BSC is designed to accept Lockout inputs from each stage. If any stage is in Lockout, the BSC will automatically skip it when
adding more capacity. If a stage goes into Lockout during normal operation, the next stage will be activated immediately to maintain
the desired output capacity.
System Output is Active when Any Stage is Active
This output can be used to activate a system pump, combustion air damper, or perform any other function that is required when any
stage is active. A System Prove input checks the status of components activated by the System output before stages can be activated.
BACnet IP Remote Communication Upgrade Available
The BSC can be upgraded to include a BACnet IP remote communication package to monitor and control all BSC functions from a
remote location.
