AUTOMATIC SUMMER MODE

This option involves automatic switching between modes. When the external temperature exceeds the activation
threshold of Summer automatic mode, the valves will close. When the external sensor detects that a given threshold has
been exceeded, the controller switches to summer mode. Average temperature is calculated on an ongoing basis. When
it is lower than the pre-set value, the operation mode will switch to the previous one.
•
Summer mode temperature threshold – this option enables the user to set the outside temperature value above
which summer mode will be enabled.
•
Averaging time – the user defines the period of time which will be used to calculate the average outside
temperature.
NOTE
This function requires the
external sensor to be active.
