B One single room
a User interface used as room thermostat
▪ The room temperature of the main room is controlled by the user
interface used as a room thermostat (optional equipment
EKRUDAS).
Configuration
Setting Value
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]
2 (Room thermostat): Unit

the ambient temperature of the
user interface.
Number of water temperature
zones:
▪ #: [4.4]
▪ Code: [7-02]
0 (Single zone): Main
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, use the holiday mode…
