• 4.2 Switching on the party function, page 15

• 4.3 Setting the time (clock), page 15

• 4.5 Setting the room temperature heating mode, page 16

• 4.6 Setting the room temperature for night reduction heating mode, page 17

• 4.7 Setting the warm water temperature, page 17

• 4.8 Adjusting the heating curve, page 18

• 4.9 Setting the maximum supply temperature, page 19

• 4.10 Setting the heating limit (summer/winter), page 19

• 4.12 Displaying temperatures and values, page 21

• 4.15 Setting the clock programs for heating/D.H.W., page 26

• 4.16 Setting an individual D.H.W. clock program P1, page 28

• 4.17 Setting the circulation pump clock program P1, page 29

All other adjustments should be made by technical personnel only.
Faulty adjustments may lead to malfunctioning o f the heating system
or may shorten its life.

2.3 Temperature information

All temperature information is:

• if measured, in °C (Celsius)

• as temperature difference in K (Kelvin)

2.4 Effectiveness of settings

• 1. level: Modified settings become immediately effective

• 2. level: Modified settings become effective by changing the parameter or by
closing the cover
