Handling and operation
The control is operated using two buttons. The control is set on three main
operating levels: the user level, the configuration level and the statistic level.
Within the operating levels, the menu items are shown in the display using
abbreviations. The menu items are selected by pressing the control buttons. A
selected menu item will show its setting alternately after 5 sec. To change to the
other operating level, set the appropriate menu item and press both buttons at the
same time.
To make a setting or a change, the selected menu item must be opened by
pressing both buttons at the same time. The "Entry Status" LED lights up and the
current setting is displayed. Pressing the control buttons allows a setting or
change to be made within one of the opened menu items.
A deviation from the last saved setting is shown when the "Entry Status" LED
flashes. Pressing both buttons at the same time closes and saves the changed
menu item. The "Entry Status" LED is switched off, thus confirming that the setting
has been correctly completed. After 5 sec. the new setting is shown alternately
with its menu item. After changing from operating level "-2-" or "-3-" to operating
level "-I-", the room temperature "tL1" is automatically shown.
Note:
If an open menu item remains unclosed, it will close automatically after 5 minutes.
The last saved setting remains unchanged. You are automatically taken back to
operating level "-I-" to the display of the room temperature "tL1".
TL1
TBL
The power supply of AC/DC 24 V may only be connected to the input terminals 4
and 5 provided for this purpose. Incorrect connection results in immediate
destruction of the control.
The digital inputs 1 and 2 and the input terminals 1, 2 and 3, as illustrated here,
may only be switched with floating contacts.
External voltage of any kind results in immediate destruction of the control and can
lead to fatal injury if disregarded. This also applies to the Pt 1000 sensor inputs
TL1 and TBL, terminals 6 to 10.

Note:
Alerts detected by the control also remain stored, even in the event of a power
failure, and are displayed again when power is restored (fault display LED, alert
and buzzer). Alerts can only be deleted under the menu item "ALt" with "cLr".
If the Power fail control "PFC" is set to "On", thus switched on, the alert "PFL" is
displayed when power is restored.
