Safety instructions
1 Safety instructions
For your own safety, follow these instructions concerning the mounting, start up and opera-
tion of the controller:
− The device is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product.
− For electrical installation, you are required to observe the relevant electrotechnical regu-
lations of the country of use as well as the regulations of the local power suppliers. Make
sure all electrical connections are installed by trained and experienced personnel! Before
performing any such work on the controller, disconnect it from the power supply.
− The device is designed for use in low voltage installations. For wiring and maintenance,
you are required to observe the relevant regulations concerning device safety and elec-
tromagnetic compatibility.
To avoid damage to any equipment, the following also applies:
− Proper shipping and storage are assumed.
− Before start-up, wait until the controller has reached the ambient temperature.
1.1 Disposal
Waste electrical and electronic equipment may still contain valuable substances. They may
also, however, contain harmful substances which were necessary for them to function. For
this reason, do not dispose of this kind of equipment together with your household waste. Se-
lect a suitable disposal method. Instead, dispose of your waste equipment by handing it over
to a designated collection point for the recycling of waste electrical and electronic equipment.

2.3 Selecting operating modes
Day mode (rated operation): regardless of the programmed times-of-use and summer mode,
the set points relevant for rated operation are used by the controller. Icon:
Night mode (reduced operation): regardless of the programmed times-of-use, the set points
relevant for reduced operation are used by the controller. Icon:
Control operation deactivated: regardless of the programmed times-of-use, control opera-
tion of the heating circuits and DHW heating remains deactivated. The frost protection is ac-
tivated, if need be. Icon:
Icons when the frost protection is activated: HC , DHW
Automatic mode: during the programmed times-of-use, the controller works in day mode.
Outside these times-of-use, the controller is in night mode, unless control operation is deacti-
vated depending on the outdoor temperature. The controller switches automatically between
both operating modes. Icon within the times-of-use: , icon outside the times-of-use:
