NIVIAN - Radiator valve

Easy installation, without draining water or interfering with the radiator circuit, simply by replacing the thermostatic valve which is attached to the metal body of the radiator valve.
Universal compatibility with most existing thermostatic (non-manual) radiator valves through different adapter threads. To identify the type of valve present, you should observe the aspect of the valve, as thermostatic valves differ from the manuals because they present some type of value scale or steps in their turning positions and a fastening screw to be able to separate the valve body, while the manuals are simple patterns indicating opening or closing with turning senses and do not incorporate any fastening screw.

The eTRV smart valve communicates wirelessly with the NVS-THERMOSTAT central communications HUB to be able to operate from the app because it needs to be ordered early.
The most outstanding features of this solution are:

• Long radio range (80 m free space) for installation on any radiator in the room.
• Stable communication.
• Battery operated, no power outlets required.
• Low consumption, average autonomy 1.5 years.

The functions we can find in the smart valve are:

• LCD display with temperature, date/time, battery, programming and mode.
• Push button panel with 3 buttons and rotary knob.
• 5 control modes for adjusting the room temperature
• Automatic programming, with 5 preset times, expandable to 9.
• Hourly, daily, weekly or full week programming.
• Fast temperature drop detection (open window).
• Antifreeze / quick heat / comfort / energy saving mode.
• Locking function to protect against accidental adjustment (children).
• Automatic weekly descaling.
• Detecting correct installation.
