TAC b3850/3851/3853 Access control controller

Technical Specification

Features:
  • Make: TAC
  • Model code: b3850/3851/3853
  • Series: Continuum Series
  • Controller Type: Networkable
  • Networkable: Yes
Additional info:

The b3850 is designed for single-duct VAV applications, with four universal inputs plus an on-board air flow sensor.  The b3851 contains four Universal inputs as well, but does not have the on-board air flow sensor and is perfect for applications such as heat pumps and fan coils.  The b3853 is for dual-duct VAV applications. It contains two on-board airflow sensors and four universal inputs.
