TAC Erie™ Three-Way Mixing Valve Control

Model Chart

Specifications

The TAC Boiler Boss

BB3600 mixing valve control

with outdoor reset provides closed loop control of

water temperature in the secondary (radiant) loop of a

heating system using a proportional control three-

way mixing valve.

The TAC Boiler Boss

BB3600 protects against boiler

condensation by monitoring and anticipating the

boiler return water temperature.

A continuously scrolling display shows the outdoor

air, loop temperatures, secondary loop setpoint and

valve signal value.

Features:

• Built-in transformer and relays.

• Real application data inputs.

• LED display for temperature settings.

• Raises or lowers secondary loop temperature based on

changes in outside air.

• Boiler low temperature protection and short-cycle protection.

• Controls a modulating valve with either a 0-10 V or 4-20 mA

signal.
