If the installation is tted with a room thermostat:
This function enables you to choose the ambient temperature's inuence on the setting.
If no value is entered, the setting is made based on the temperature control.
If the parameter is set at 100%, the setting is only based on the ambient temperature.

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.

1060 S Room temperature limitation 0,5... 4 °C 0.5 °C 0.5 °C
As soon as the room temperature = [Setpoint line 1010 (ex. 20°C) + Room temperature limitation setpoint line 1060
(ex. 0,5 °C)] > 20,5 °C => The heat pump is stopped.
It restarts when the room temperature falls below the setpoint (in the example, Room temperature < 20,0 °C).
