Specifications
The TAC Boiler Boss
®
BB3000 injection pump mixing
control with outdoor reset provides closed loop
control of water temperature in the secondary
(radiant) loop of a primary/secondary heating system.
The TAC Boiler Boss BB3000 also protects against
boiler condensation by monitoring and anticipating
the boiler return water temperature.
The outdoor air and loop temperatures are displayed
continuously, along with the secondary loop setpoint
and pump speed.
Features:
• Built-in transformer and relays.
• Sure start pump control.
• Real application data inputs.
• LED display for temperatures and settings.
• Raises or lowers secondary loop temperature based on
changes in outside air.
• Boiler low temperature protection and short-cycle protection.
