AController for electronic feedback BTemperature matching controller
Electronic feedback (hysteresis setting)
The switching hysteresis is influenced by the electronic feedback.
At the factory, the Vitotrol 100 is set to standard mode. Only change this setting
if the control unit must be adapted to the heating system.
AStandard mode (delivered condi-
tion)
Bring the controller for the electronic
feedback into the required position
using a screwdriver.

Temperature matching
A matching of temperatures may be required to adapt the controller to local con-
ditions, e.g. when installing it on a cold concrete wall.
&Regulated temperature too high:
Turn the controller towards "–"to
adjust the temperature
&Regulated temperature too low:
Turn the controller towards "+" to
adjust the temperature
Repeat if required after the room tem-
perature has stabilised.
Note
The Vitotrol 100 requires approx.
1houraftercommissioningtoassimi-
late to the ambient temperature.
Users should only then make adjust-
ments to suit their personal require-
ments.
DHW heating
The DHW heating function can be modified at the rotary selector at the back of
the Vitotrol.
In the delivered condition, the rotary selector is set to "1".

Several clock thermostats and wireless receivers can be installed in a single
building. Both are matched up to each other in the factory. If several clock ther-
mostats are fitted with the wireless receiver in a single building complex, never
swap the respective clock thermostat and wireless receiver, as each clock ther-
mostat can only communicate with the respectively allocated wireless receiver.
Testing the strength of reception
At the back of the clock thermostat,
turn the rotary selector to "10".
The clock thermostat sends a signal
every 4 s for a duration of 5 minutes.
The reception signal strength is indi-
cated by the number of lit LEDs. See
the following table.
After commissioning, set the rotary
selector of the wireless receiver back
to the required position for DHW heat-
ing(seepage11).
