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.
