When the average of the outdoor temperatures over the past 24 hours reaches 18°C, the
regulator switches off the heating (as an economy measure). During summer mode, the display
shows "Eco". This function is only active in automatic mode.

As soon as the room temperature = [Setpoint line 710 (ex. 20°C) + Room temperature limitation
setpoint line 760 (ex. 0.5°C)] > 20.5°C → The heat pump is stopped.

It restarts when the room temperature falls below the setpoint.
(ex. room temperature < 20.0°C)
