Thermostat is used for time- and temperature controlled additional heating.
See Thermostat 1

6.6.2.7. - Energy saving mode

Energy saving mode switches the heating on when T eco is undershot und heats up to T eco + 

hysteresis when solar charge is active.

Settings range: On, Off / Default setting: Off

6.6.2.8. - Periods

Thermostat activity times

Set the desired periods of time when the thermostat should be active. 3 periods can be set per 
day, settings can also be copied to other days. Outside the set times the thermostat is switched 
off.

Setting range: from 00:00 to 23:59 /default setting: 06:00 to 22:00

6.6.3. - Thermostat 2
