When the mean of the external temperatures over the last 24 hours reaches 18°C the regulator stops the heating (economy).
In summer operation, the display shows "Eco". This function is only active in automatic operation.

This function permits, between seasons, to deviate partially from the automatic switching between summer/winter.
If the value is increased, the switch to summer operation is delayed.
If the value is reduced, the switch to summer operation is brought forward.
This function is only active in automatic operation.

If the installation is equipped with an ambient sensor:
This function allows the influence of the ambient temperature on the regulation to be chosen.
If no value is entered, the regulation is via the water logic.
If the parameter is set to 100%, the regulation is only made using the ambient temperature.
