5.2 Checklist: Important settings for
commissioning
Always perform commissioning so that the system operates as
needed. Based on experience, the following settings are very
important to satisfy the system user:
• Control type: outdoor reset ( ) with or without the
influence of the room temperature, or room temperature-
dependent
• Heating curve ( ): Adapted with reference to the
design temperature, minimum outdoor temperature and
other settings
• DHW priority: A heat demand for hot water has priority or
hot water and heating have the same priority (if possible
hydraulically)
• Time program: Determines when heating is active, see
user manual for details.
How to change settings in the service menu is described in
Chapter 8. Alternatively see the user manuals.
