The Green leaf indication informs you that the system offers an energy-optimized mode. When the heating output is energized and if the thermostat detects that the room air temperature is 2 K higher than the default heating setpoint for “Comfort” or “Economy”, the leaf icon turns to red . Touch the red leaf on either the thermostat's home screen or the temperature control widget of the mobile application to switch the setting back to an energy-optimized operation:

  • Control the temperature according to Green Leaf default setpoints for heating.
  • Operate an actuator, boiler or compressor automatically based on a schedule.
  • Switch to follow a schedule with a pre-set setpoint that you’ve defined under “Advanced Settings” > “Optimization” in the thermostat.
