Features & Benefits
Correct return temperature from terminal units
Built-in return temperature controller keeps the return temperature on a pre-set value and ensures high energy efficiency of the cooling system.
Hydronic balancing
Overflows are limited by return temperature control.
Measuring
Self-sealed measuring point for temperature measuring and monitoring.
