All the basic settings will have already been carried out by
Hoval, or the heating engineer, during commissioning of
the heating system. You can make further settings if you
go on a journey or if your home is too cold or too warm.
You can nd an overview of the most frequently asked
questions in chapter 6.3 page 16.
How to save energy!
For your benet and for the environment
Using energy more e󰀩ciently by avoiding unnecessary
losses! With little e󰀨ort, you can optimise the operation of
your heating system and save energy at the same time.
It is worth setting your personal day and week pro-
grams
You can save valuable energy and money by specically
adjusting the heating times with a personal day or week
program to take account of the times when you will be
present and absent. The TopTronic®E control makes it
very simple to set di󰀨erent switching cycles for individual
daily sequences (chapter 6.9 page 34).
6.2 Operating and display elements
The graphical displays on the control module can be ope-
rating or display elements.
If the TopTronic®
E control module is in sleep

6.4 Efficient control of the system
You can save a lot of energy by e󰀩cient adjustment of
the heating operation. The TopTronic®E control module
provides basic programs (6.8 page 31) that help you
to control your system easily and specically when you
are present and absent over a fairly long period of time.
For short-term changes to the heating times, you can use
various day programs in the Week 1 and Week 2 basic
programs (6.10 page 43). Furthermore, the living area
temperature can be increased or reduced e󰀨ortlessly by
selecting the current room temperature.

6.5 Individual day and week programs
To save you the trouble of selecting the required basic
program every day, the control module of the TopTronic®
E o󰀨ers you the opportunity of using week programs. In
the two basic programs that can be selected, you can
plan your individual week sequences and assign day
programs (6.10 page 43) to adapt the heating times
to your presence and absence using switching cycles. In
Change
the basic settings, the control module already contains
the two standard week programs, Week 1 and Week 2
(6.8 page 31). You can edit the two week programs
individually (6.9.4 page 37) and give them any name
(6.9.5 page 39).
