How to use
Install the INVENA CZ-50-K15-W on the radiator inlet or outlet with compatible 1/2" fittings according to the heating system layout and manufacturer installation guidance. After mounting, set the desired temperature on the thermostatic head (if applicable) or allow the valve to operate automatically. The valve will open or close gradually in response to room temperature changes, regulating flow to maintain the chosen thermal setpoint. Ensure the system is depressurized before installation and that connections are sealed to prevent leaks.
Usage recommendations
For reliable performance, use the valve on clean, properly flushed heating circuits and follow routine system maintenance. Avoid installing the thermostatic head behind curtains or furniture that can affect temperature sensing.
