Product Description

The Universal Controller is an advanced multi-purpose controller designed for heating and cooling system management with multiple control circuits. It is available in panel-mounted and DIN-rail versions. Developed as a replacement for the IR33 Universal series, it inherits core functionalities while introducing enhanced features, higher configurability, and modern parameterization via application.

Key Functions

  • Independent summer/winter management for Circuit 1 and Circuit 2
  • Control of up to two 3-point valves (Circuit 1 and Circuit 2)
  • Revised compensation function linked to a third additional sensor
  • Management of up to three control loops (main + auxiliary + compensation)
  • Time scheduling management:
    • 3 programs
    • 4 daily time slots
    • Off / Comfort / Eco profiles with independent setpoints
  • Parameterization via smartphone or PC using the Applica application
