HVAC controller

Block diagram


Our integrated circuits and reference designs help you create a differentiated heating, ventilation and air conditioning (HVAC) controller design for building management systems with maximum efficiency and lower system power.

Design requirements

HVAC controller designs often require:

  • New environmental sensors on the same 4-20mA loop.
  • Support for multiple wired and wireless standards.
  • Noise-tolerant capacitive touch human machine interface (HMI) to replace traditional mechanical buttons.
  • Precise motor control of system actuators and valves to increase overall system efficiency.
