Benefits

▪ Highest comfort and efficiency. The smart room thermostat functionality can

decrease or increase the desired leaving water temperature based on the actual

room temperature (modulation). This results in:

- Stable room temperature matching the desired temperature (higher comfort)

- Less ON/OFF cycles (more quiet, higher comfort and higher efficiency)

- Lowest possible leaving water temperature (higher efficiency)

▪ Easy. You can easily set the desired room temperature via the user interface:

- For your daily needs, you can use preset values and schedules.

- To deviate from your daily needs, you can temporarily overrule the preset

values and schedules, or use the holiday mode.
