Menu Functions
36
Functions that have already been entered can be deleted at any time. It is recommended that a func-
tion be deleted if function data are available from a similar project and the changes that have to be
made are minor. To do so, you will find the command "
DELETE FUNCTION
" at the end of the menu
in each function module.
The command "
INSERT FUNCTION
" allows you to insert a function module before the one currently
selected. This function allows you to add a function module before or after another one in the over-
view at any time.
Function status
Function modules have a multitude of parameters that influence the output variables accordingly. It is
thus not that easy to tell why an output is blocked or cleared any given time. For example,
HEAT.CIRC.CONT
has some 10 function parameters, such as enable, mood, switch-off conditions,
that determine whether the heating circuit pump is enabled. The entry "FUNCTION STATUS" at the
beginning of every basic menu provides a quick overview of the status.
This submenu lists all of the effective functional elements, with a
to the right indicating that is acti-
vated. Each functional element that does not have a check at the end of the line blocks the output
variables at that moment.
Indication example:
ENABLE HTG CIRC.2
ENABLE PUMP
ENABLE MIXER
HEATING CIRCUIT PUMP:
Status: OFF
MIXER:
Status: off
Rem rutime 0.0 Sec
FROST PROT.MODE
LIMIT T.flowSET :
T.flow: SET < MAX.
T.flow: SET > MIN.
SHUTDOWN CONDITIONS:
T.room: ACT < SET
T.flow: SEt > MIN.
The remaining running time of the mixer is reloaded after a
direction change or granted enable and always equals 20
minutes independent of the set mixer running time.
In this example, the heating circuit pump is currently blocked (status = OFF) because the specified
room temperature has been exceeded
(
Switching condition
T.room: ACT < SET
is not fulfilled).
In addition to the main functional elements, this submenu also always indicates all of the output varia-
bles along with their current output status.
