730 I Summer / Winter heating limits
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.

Floor heating system = 50 °C / Radiators = 65 °C.
Important Note : Maximum temperature limitation is not a safety function as required by ground heating.
750 S Room influence
If the installation is fitted with a room thermostat:
This function enables you to choose the ambient temperature's influence 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.
760 S Room temperature limitation
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 (in the example, Room temperature < 20,0 °C).
