CAREL UNIVERSAL KONTROLER – IR 33 UNIVERSAL UPGRADE

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
