Operation

1 Operation

The controller is ready for use with the temperatures and operating time schedules preset by the manufacturer. On start-up, the current time and date need to be set at the controller (–> section 1.5).

1.1 Control knob

Turn q:

Select parameters, displays and temperature displays

Press :

Confirm adjusted selection or settings

Press for three seconds 3s:

Switch from the operating level to the user level as well as from the user level to the installation level

1.2 Operating modes

Automatic mode

Display: and in the time-of-use periods, and outside of the times-of-use periods The controller works in rated operation within the programmed times-of-uses and in reduced operation outside of the times-of-use, provided that the control operation is not deactivated due to the outdoor temperature. The controller switches automatically between both operating modes.

Day mode (constant rated operation)

Display: Regardless of the programmed times-of-use, the set points relevant for rated operation are used constantly by the controller.

Stand-by mode (vacation mode)

Display: In stand-by mode, the heating is switched off regardless of the programmed times-of-use. The frost protection mode is still active.

Night mode (reduced operation; can only be set over the room panel)

Display: Regardless of the programmed times-of-use, the set points relevant for reduced operation are used constantly by the controller.

Operation

1.3 Display

The current set point appears on the display during operation. Which set point is displayed depends on:

The configured type of control

The programmed times-of-use

Weather-compensated control, room set point mode (F1 - 1 and F9 - 1)

Day set point (time-of-use period)* or night set point (outside of time-of-use period)

Weather-compensated control (F1 - 1 and F9 - 0), fixed set point control (F1 - 0 and F7 - 0)

Flow temperature (times-of-use period)* or reduced flow temperature (outside of time-of-use period)

The set point (left) and the measured value (right) are displayed in this example.

* Appears on the depicted display

Note!

The icon appears additionally on the display for a control functioning with the room panel unit (F7- 1). A temporarily active set point (corrected once) is indicated on the display by the icon together with the icon (refer to section 1.9.1). An active function for drying of jointless floors is indicated on the display by the icon together with the icon (refer to section 5.3).

1.5 Setting the system time

The current time and date need to be set immediately after start-up and after a power failure lasting more than 72 hours has occurred. This is indicated by the time blinking on the dis play. The time is already in the edit mode and can be changed directly. The first two instruc tions steps are then omitted.

Note! On initial start-up and after a power failure lasting more than 72 hours, the controller switches automatically to the operating level after the date has been set and confirmed. The last two steps are omitted.

Note! The controller automatically switches to the operating level if the control knob is left untouched for five minutes.

EB 5432 EN 9

Operation

1.6 Setting the times-of-use

Three time-of-use periods can be set for each day of the week. If not all the time-of-use periods are required, the start and stop times of the third time-of-use period (for just two periods) must be set to identical times or, alternatively, the start and stop times of the second time-of-use (for just one period). The controller then automatically sets the start and stop times to the stop time of the previous time-of-use period. The times-of-use are displayed in the user level (–> Fig. 10 on page 49).

Note!

You can set the times-of-use for each day or for an entire week. If you want to set the times-of-use for certain days to be different than the rest of the week, we recommend you set the times-of-use for the entire week first (display: ) and then al ter the times-of-use for each day which require different times-of-use. The week setting of the times-of-use writes over any already programmed times-of-use.

2.1 Configuration and parameterization

The controller is configured and parameterized in the configuration and parameterization level (–> Fig. 10 on page 49). After accessing the configuration and parameterization level (CoPa level), the function blocks F1 to F9 appear at first, followed by the parameters P1 to P18. The individual functions and parameters are listed in the Appendix (–> page 41). The configuration and parameterization level is locked to prevent unintentional and unautho rized access. This level can only be opened when the key number is known. The key number can be found on page 48. To avoid unauthorized use of the key number, remove the page or make the key number unreadable.
