▪ 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.
