Output variables
They represent the result of a function module. They can be used directly for the switching of hard-
ware output or serve as input variable for another module. If this output variable is to be used directly
for the switching of a pump, the assignment can be made in the menu “OUTPUT VARIABLE” of the
module. The output variable is always available as input variable for the other modules
with or with-
out
assignment to a real output.
The previous example, the module solar control unit, normally creates an output out of a difference
function together with a thermostat function (such as: difference already reached, cylinder tempera-
ture limit not yet reached => output variable (=
ON
). This information can now be assigned to a hard-
ware output under ”output variable”.
Indication example
(we are already in the menu of the function 6 = SOLAR 1):
DES: SOLAR 1
FUNCTION STATUS:
INPUT VARIABLE:
OUTPUT VARIABLE:
◄
COLLECTOR TEMP.:
Other text lines by scrolling
After entering the menu “OUTPUT VARIABLE” the following menu appears:
SOLAR 1
SOLAR CIRC:
Status: OFF
OUTPUT:
1 2 3 4 5 6 7 8
9 10 11 12 13 14
15 (=analog=) 16
The output variable actually shows the status
OFF
, i.e. either the set temperature difference has yet
not been reached or the cylinder limit has been exceeded. Now, the variable is to be assigned to the
real (hardware) output 1.
To do this, induce the pointer to 1 and make the assignment by the usual operation - / press / darken
the 1 / press.
Now, the display shows:
SOLAR 1
Above the visible range
SOLAR CIRC:
Status: OFF
OUTPUT:
1
◄
2 3 4 5 6 7 8
9 10 11 12 13 14
15 (=analog=) 16
Below the visible range
Hence, the function
SOLAR 1
influences the output 1.
