Additional Information for Installers
You can check functions quickly with the “FUNCTION
STATUS” subfunction that is available at the start of most
function menus (
figure on right
).
The following example explains the “FUNCTION STATUS”
menu using heating circuit 1 as an example:
• “ENABLE HEAT CIR.1/PUMP/MIXER”
: If the line has a
check mark (
✓
), it means that the function can control
this object. In the figure below, for example, the pump is
not enabled. This can be due to many reasons. To find
out which ones, proceed to the next step by looking at
the input variables. For example, it shows that a hot
water priority is defined, which means the pump is
blocked when the hot water buffer requires auxiliary
heating. In the next step, you would need to determine
whether there is a requirement arising from the hot
water.
• “Status” of “HEAT CIRCUIT PUMP”/”MIXER”
: Tells
the status of the output as controlled by the function.
Compare this information with the display of the sta-
tuses of the outputs in the first line (no. 3 is highlighted
in black: Pump “on” otherwise “off”, no. 8 black:
Mixer “op.”, no. 9 black: Mixer “cl.”, otherwise “off”).
Example
: If the “HEAT CIR.1” function and the pump are
both enabled, “Status” of the heating circuit pump will
show whether or not the pump is operating. However, if
the “HEAT CIR.1” function is not enabled, (for example,
because the “Floor Dry” function is active), the pump
status will always be off, regardless of whether it was
activated by the “Floor Dry” function or not.
• “FROST PROTECTION MODE”
: If the line has a check
mark (
✓
), it means that the respective heating circuit is
in frost protection mode.
• “LIMIT T.Pre.NOM”
: A check mark (
✓
) behind the
queries means that the target flow (“pre-run”) tempera-
ture is within the limits “T.Pre.MIN” and “T.Pre.MAX”.
• “SWITCH-OFF COND.”
: Here, the queries of the switch-
off conditions from the respective heating circuit are
given inversely, which means if all switch-off conditions
are met, the pump would not be shut off. Only the last
query “LOWERING MODE and T.Out.: ACT. < MIN” is eval-
uated when the heating circuit is in lowering mode.
