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 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 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
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.

2.2 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 op-
eration remains deactivated. The frost protection is activated, if need be. Icon:
Automatic mode: during the programmed times-of-use, the controller works in day mode
(rated operation). Outside these times-of-use, the controller is in night mode (reduced oper-
ation), provided control operation has not been deactivated due to the outdoor temperature.
The controller switches automatically between both operating modes. Icon:

Different hydraulic schematics are available. Each system configuration is represented by a
system code number. The different schematics are dealt with in section5. Available control-
ler functions are described in sections6, 7 and 8.
Changing the system code number resets previously adjusted function blocks to their default
settings (WE). Function block parameters and parameter level settings remain unchanged.
The system code number is set in the configuration and parameter level.
