•Now set the day and time the same way as described for setting an extra period in the week menu (11.11 "Programming an extra period"). In this case however, the pump will be automatically started.
•Select START to start.

The default is NO.

Note
The first time the appliance is started, it is necessary to check whether this setting corresponds with the configuration of the solar heating system.
12.9.2Setting the heating fluid type in the solar heating system
Use this menu to specify the type of heating fluid used to fill the solar heating system (2.6 "Protection for the solar heating system"). Call up the menu as follows:
•: SETTINGS SOLAR TYPE OF FLUID
You can select from Glycol and Water. The default is Glycol.
TYPE OF FLUID »Glycol Water
Note
The first time the appliance is started, it is necessary to check whether this setting corresponds with the configuration of the solar heating system.
Note
The setting Water is currently not possible
12.9.3Setting threshold temperature of pump in solar heating system
The pump of the solar heating system is switched on when the difference (9.3 "The appliance's heating cycle") between the temperature at the top of the solar collector (sensor S1) and that in the appliance (sensor S2) exceeds a certain value. This value can be set to between 5 and 20 °C. Call up this menu as follows:
•: SETTINGS SOLAR DELTA T SOLAR
The default value is 10 °C.
DELTA T SOLAR
10ÉC
12.9.4Setting the solar limit temperature
The solar limit temperature is the maximum water temperature obtained in the appliance via the solar heating system (measured by sensor T1).
This value can be set between 65 ... 80 °C. The default value is 65 °C.
If you set the solar limit higher than the set
point (11.4 "Setting the water temperature"), then once the set point is reached, the solar pump will be started to heat the water further. However, this only makes sense if the solar heating system is actually generating heat. This makes use of the difference between the temperature at the top of the solar collector (S1) and that in the appliance (measured by S2). This value is also adjustable (12.9.3 "Setting threshold temperature of pump in solar heating system").
Call up the menu for the solar limit as follows:
•: SETTINGS SOLAR SOLAR LIMIT SOLAR LIMIT
65ÉC
12.9.5Setting the solar difference
The solar difference is a value that influences how the heating cycle of the appliance proceeds. Call up the menu as follows:
