modulardigitalelectronic

Product overview
The Universa heating circulation thermostats cover bath volumes from 4 to 40 L and heating outputs between 2 kW and 3.6 kW, providing flexible configuration options for industrial temperature-control applications.

Features

• Bath circulation thermostat with advanced electronics for precise temperature control
• Dedicated Tmax button for quick access to overtemperature protection during commissioning
• Adaptive bath-edge ventilation (patent pending) to prevent icing and condensation, stop water ingress and block vapours to protect electronics
• Flexible networking: integrated Ethernet and USB as standard plus eleven optional interface modules
• Integrated Wi‑Fi (device import/use limited to certified regions: USA, Canada, EU incl. UK and Switzerland, and India)
• Modular design with interchangeable control head and heating/cooling base for future upgrades
• Efficient vario pump with six adjustable power levels for internal and external circulation
• Programmer, calibration options and weekly scheduler for precise process control
• 3.5-inch colour TFT display with trend graph, menu navigation in six languages and cursor/soft-key operation
• Front switch on the control head for pump output adjustment during operation
• Remote control and monitoring: integrated web server, LAUDA Command app or browser control secured by PKI and 2-factor authentication; connection to LAUDA.LIVE for cloud data analysis and remote maintenance
• Comprehensive safety concept: float-type low-level protection, adjustable overtemperature protection with acoustic alarm, smart thermostating-media management
