System safety:
■When connecting the remote control to the power
supply, only use the plug-in power supply unit provi-
ded or the power supply unit for flush mounting.
■The heating system and the functionality of the mes-
sage paths must be tested at regular intervals.
■To improve the operational reliability of the heating
system, we recommend implementing supplemen-
tary measures, e.g. frost protection or monitoring for
water damage.
System requirements for a reliable WiFi internet
connection:
■WiFi router with activated WiFi:
The WiFi router must be protected by a sufficiently
secure WPA2 password.
Do not use unencrypted connections between the
heat generator and the WiFi router.
■Internet connection with high availability:
Flat rate (flat rate tariff without restriction on time or
data volume)
■Dynamic IP addressing (DHCP, delivered condition)
in the network (WiFi):
Have this checked on site, and if required set up, by
an IT expert prior to commissioning.
■Set routing and security parameters in the IP net-
work (LAN):
Enable port 80, port 123, port 443 and port 8883 for
direct outward connections.
Have this checked and, if necessary, set up on site
by an IT expert before commissioning.
Reliable remote control operation:
■The heat generator control unit and the
Vitotrol 300-E remote control must be connected via
low power radio.
■At least 1 heating circuit must be assigned to the
remote control (settings to be input by the contractor
at the control unit of the heat generator).
■Commissioning has been carried out.
■The remote control's full range of functions is only
available if the software is up to date:
To enable software updates, the heat generator has
to be connected to the internet via a WiFi router. The
download always takes place via the Viessmann
server.
Automatic software updates only occur if a perma-
nent internet connection is provided via the heat gen-
erator (recommendation).

Energy saving tips
Saving energy when using central heating
■Do not overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Do not set your individual preferred temperature too
high, e.g. not above 20 °C: See page 23.
■Heat your home to the reduced temperature at night
or during regular absences (not applicable to under-
floor heating). To do so, set the time programs for
central heating. These settings can only be made at
the control unit of the heat generator.
Heat generator operating instructions
■To switch off functions that are not required (e.g.
central heating in summer), select the "Only DHW"
and "Standby mode" operating programs. These set-
tings can only be made at the control unit of the heat
generator.
Heat generator operating instructions
■If you are going away, set the "Holiday program"
: See page 24.
During the period that you are away, the room tem-
perature will be reduced and DHW heating switched
off.
Saving energy on DHW heating
■At night or during regular absences, heat the DHW to
a lower temperature. To do so, adjust the settings in
the time program for DHW heating. These settings
can only be made at the control unit of the heat gen-
erator.
Heat generator operating instructions
■Switch on DHW circulation only for those times in
which you regularly use hot water. To do so, adjust
the settings in the time program for the DHW circula-
tion pump. These settings can only be made at the
control unit of the heat generator.
Heat generator operating instructions
For additional energy saving functions, e.g. on the con-
trol unit, please contact your contractor.
Tips for greater comfort
More comfort in your home
■Set your individual preferred temperature: See
page 23.
■Adjust the time program for your heating so that your
individual preferred temperature is automatically
reached when you are present. These settings can
only be made at the control unit of the heat genera-
tor.

Check the reception quality at the intended installa-
tion site: See the following chapter.
Checking the reception quality at the installation location
In order to check the reception quality at the intended
installation location, first start the Vitotrol 300-E: See
page 19.
Press the following buttons:
1. Operating button C: See Fig. 8, page 20.
2. to select "Device info".
3. to select "SHOW".
4. to call up the signal strength for "WiFi Status"
or "Low Power Radio Status".
Note
To ensure a stable wireless connection, we recom-
mend a signal strength of at least –75 dBm: See the
following table.
Meaning of display
Display Value in dBm Reception quality
0 to –55 Very good
–56 to –65 Good
–66 to –75 Adequate
–76 to –85 Inadequate
–86 to –... No reception
Range of the wireless signal
The range of wireless signals may be reduced by
walls, ceilings and interior fixtures. These weaken the
wireless signal, causing poor reception due to the fol-
lowing circumstances.
■On their way between transmitter and receiver, wire-
less signals are damped, e.g. by air or when pene-
trating walls.
■Wireless signals are reflected by metallic objects
e.g. reinforcements embedded in walls, metal foil of
thermal insulation and thermal glazing with metal-
lised thermal vapour deposit.
■Wireless signals are isolated by service ducts and
lift shafts.
■Wireless signals are disrupted by devices that also
operate with high frequency signals. Maintain a dis-
tance of at least 2 m from these devices:
–Computers
–Audio and video systems
–Devices with active WiFi connection
–Electronic transformers
–Pre-ballasts

Angle of penetration
The reception quality remains best if radio signals hit
the walls vertically.
Depending on the angle of penetration, the effective
wall thickness changes and so does the extent to
which the electromagnetic waves are damped.

Isolators for non-earthed conductors
■Install an isolator in the power cable to provide
omnipolar separation from the mains for all active
conductors, corresponding to overvoltage category
III (3 mm) for full isolation. The isolator must be fitted
in the permanent electrical installation, in line with
installation requirements.
■We additionally recommend installing an AC/DC-
sensitive RCD, type B , for DC (fault) currents
that can occur with energy efficient equipment.
Danger
Incorrect electrical installations can lead to seri-
ous injury from electrical current and result in
appliance damage.
Connect the power supply and implement all
safety measures (e.g. RCD circuit) in accord-
ance with the following regulations:
■IEC 60364-4-41
■VDE regulations
■TAR medium voltage VDE-AR-N-4110
Danger
Incorrect core assignment can lead to serious
injury from electrical current and result in appli-
ance damage.
Never interchange cores "L" and "N".
Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
Take the following measures to prevent wires
drifting into the adjacent voltage area:
■Route extra low voltage (ELV) leads < 42 V
separately from cables > 42 V/230 V~/400 V~
and secure with cable ties.
■Only strip the minimum of insulation from
cables as close as possible to the terminals
and bundle tightly to the corresponding termi-
nals.

firm your selection with .
3. Follow the instructions on the Vitotrol 300-E dis-
play.
Note
After commissioning has been successfully completed
and if the WiFi of the heat generator is active, the WiFi
connection data of the heat generator is transmitted to
the Vitotrol via low power radio. The Vitotrol uses the
WiFi connection data of the heat generator for con-
necting to the Viessmann server.
Assigning the remote control to the heating circuits
You can operate up to 4 heating circuits with your
Vitotrol 300-E. Your contractor will assign the Vitotrol to
the required heating circuits at your heat generator
control unit. The settings at the heat generator control
unit are transferred to the Vitotrol 300-E during com-
missioning.
