MANUALLY TERMINATING SCREED HEATING
PROGRAM
SYSTEM CONFIGURATION
NOTICE
If there is a type of use which is not required for your sys-
tem, it is not necessary for the associated program areas to
be represented in the screen.
An example: Your system is only designed for heating
mode. No components are installed for the domestic hot
water preparation. That means you do not require access
to the menus of the program area “Domestic hot water”. It
is therefore not necessary for these menus to be shown in
the screen. In the “System conguration” you can specify
that these menus do not appear in the screen and there-
fore remain hidden..
NOTICE
However, hiding a menu does not aect the function or
operation of a type of use. If the type of use is switched o,
this must be set in the menu “Mode of operation”.
Deselect program area not required.
The example shown reveals that the menus of the pro-
gram area “Heating” are displayed in the screen. The me-
nus of the program area “Domestic hot water” are not
displayed.
NOTICE
If you respond to the conrmation prompt with , the
screed heating program will not start, If you respond to the
conrmation prompt with , the screen will change back
to the menu “Service screed heating”.
After starting the screed heating program, the programmed ow
temperature levels are automatically executed in succession.
The time interval set for a ow temperature level is not necessari-
ly the actual time which is necessary to reach the next ow tem-
perature level. Depending on the heating system and power of
the heat pump, it may take varying lengths of time until the next
ow temperature level is reached.
If a ow temperature level is not reached on account of too low a
heating power, a corresponding error message will appear in the
screen. The error message informs you about the ow tempera-
ture level which has not been reached. However, the screed hea-
ting program continues running and attempts to reach the next
ow temperature levels.
NOTICE
After expiry of a ow temperature level, the relevant time
interval is set to “0h”. This ensures that the screed heating
program continues after a potential power failure at the
start of each ow level at which it was interrupted.
NOTICE
If the error message “Power screed heating” appears (= er-
ror number 730), this is only an indication that the screed
heating program could not process a ow temperature le-
vel in the specied time interval. The screed heating pro-
gram continues to run nevertheless. The error message
can only be acknowledged if the screed heating program
has nished or has been manually switched o
NOTICE
As long as the screed heating program is running, the cor-
responding program symbol will appear in the navigation
screen: :
