Safety instructions
1 Safety instructions
For your own safety, follow these instructions concerning the mounting, start up and oper-
ation 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 reg-
ulations 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 person-
nel! 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 mainte-
nance, you are required to observe the relevant regulations concerning device safety
and electromagnetic 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.
Select 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 sum-
mer 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:

operation of the heating circuits and DHW heating remains deactivated. The frost protec-
tion is activated, 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 deactivated depending on the outdoor temperature. The controller switches automatical-
ly between both operating modes. Icon within the times-of-use: , icon outside the
