6.3 Control levels
Upon connection to the power supply during start-up, the controller automatically switches to
the operating level. To configure the controller, you must first switch over to the configuration
level and then the parameter level.
6.3.1 Configuration level:
You can adapt the controller to the individual system requirements
using the functions available.
6.3.2 Parameter level:
You can enter user data such as the time, date, heating characteristic,
set points, times-of-use, etc.
6.1.3 Operating level:
On this level, the controller is standard set to rated operation with time-
controlled switchover to reduced or standby operation.
Use the mode switches to change to other operating modes; times-of-use and current operating
states are indicated in the display.
As a rule, the basic display (Fig. 22) appears with the current time and bars indicating the cur-
rent times-of-use as well as various operating states.
If you keep the key pressed down when the time appears in the display, the display alternates
between the current date and year.
If you want to display other values, e.g. current temperature values, proceed as follows:
Press the arrow key to view next display or
Press the arrow key to view the previous display
If you want to view the associated set point instead of the current temperature value, keep the
key pressed down.
If you continue to press the key, other images appear in the display with other symbols. These
depend on the system code entered during configuration (see chapter 7.1) as well as the ad-
justed function blocks.
