11.1.25 How does the temperature switching differential work?
The temperature switching differential can be controlled by PID algorithm and “2-
position”. You can check the option under “Advanced Settings”> “Optimization”>
“Heating control loop”.
The differential is controlled by PID algorithm based on heating request.
The differential is controlled by “2-position”. The hysteresis value is 0.5 °C. When
the room temperature is 0.5 °C above the setpoint, the thermostat stops heating.
When the room temperature is 0.5 °C below the setpoint, the thermostat starts
heating.
The temperature switching differential work cannot be directly influenced by the
user.

11.3 Cyber security disclaimer
Siemens provides a portfolio of products, solutions, systems and services that
includes security functions that support the secure operation of plants, systems,
machines and networks. In the field of Building Technologies, this includes building
automation and control, fire safety, security management as well as physical
security systems.
In order to protect plants, systems, machines and networks against cyber threats, it
is necessary to implement – and continuously maintain – a holistic, state-of-the-art
security concept. Siemens’ portfolio only forms one element of such a concept.
You are responsible for preventing unauthorized access to your plants, systems,
machines and networks which should only be connected to an enterprise network
or the internet if and to the extent such a connection is necessary and only when
appropriate security measures (e.g. firewalls and/or network segmentation) are in
place. Additionally, Siemens’ guidance on appropriate security measures should be
taken into account. For additional information, please contact your Siemens sales
representative or visit https://www.siemens.com/global/en/home/company/topic-
areas/future-of-manufacturing/industrial-security.html.
Siemens’ portfolio undergoes continuous development to make it more secure.
Siemens strongly recommends that updates are applied as soon as they are
available and that the latest versions are used. Use of versions that are no longer
supported, and failure to apply the latest updates may increase your exposure to
cyber threats. Siemens strongly recommends to comply with security advisories on
the latest security threats, patches and other related measures, published, among
others, under https://www.siemens.com/cert/en/cert-security-advisories.htm.
