DISPLAY
In the "Display" menu the user can specify what infor-
mation will be displayed on the screen.
GRAPH
In this menu, you can set the options for the time-tem-
perature diagram.
Automatic:
The scaling of the temperature axis (Y-axis) is automati-
cally determined, depending on the target temperature
and the actual internal and external temperature.
The time axis (X-axis) is permanently scaled to 30 min-
utes.
Manual:
Axis Assignment:
The temperature values to be displayed can be selected.
Axis scaling:
Scaling of the time (X) and temperature axis (Y) can be
selected or set.
PROGRAMS
Under programs, 10 user-defined temperature-time pro-
files can be created. In addition, the pump speed and
behaviour of the external switching outputs (MODULE
M1 and M2) can be defined. A program can consist of
up to 10 segments.
Once a program has been selected, the following op-
tions are available:
Start: Starts the program upon request of loop mode.
Infinite loop: Upon completion of the last segment,
the program continues with the first segment until the
user ends the program by stopping a device function.
Loop number: Indicates the total number of loop cy-
cles until program end.
Note: At the end of the program all device functions
are switched off.
Edit: Edit/change program parameters.
Seg No.: Segment number.
Ctrl. Sensor (int/ext): Determines whether control is
through the internal (int) or external (ext) temperature
sensor.
Temp.: Target temperature.
Ctrl.Mode (Time / +/- x.x K): In "Ctrl.Mode Time"
the target values and settings of the segment are
valid for the duration indicated in the column "Time
hh:mm".
Afterwards, the next program segment is automatically
executed.
In "Ctrl.Mode +/- x.xx K", the hysteresis (tolerance)
of the actual temperature to the target temperature is
set (e.g. +/- 0.1 K). The target values and settings of the
segment are valid until the actual temperature reaches
the target temperature +/- hysteresis for the first time.
Afterwards, the next program segment is automatically
executed.
Pump rpm: Target speed of pump.
M1 (ON / OFF): MODULES M1-Valve:
OFF: M1 valve in initial state
ON: M1 valve in inverted initial state.
Note: The initial state of the M1 valve is defined in
"MODULES M1-Valve" in "Default Status" as
"Open" or "Closed".
M2 (ON/OFF): MODULES M2-Output switch
OFF: M2-output switch in initial state.
ON: M2-output switch in inverted initial state.
Note: The initial state of the M2-Output switch is de-
fined in "MODULES M1-valve" in "Default Status"
as "Open" or "Closed".
Delete: Deletes the selection highlighted in yellow (seg-
ment or program).
Insert: Inserts a new program segment after the se-
lected segment.
Save: Saves changes.
Display: Temperature-time overview displays for the
program with segments of the selected program.
Note: If hysteresis is set as "Ctrl.Mode +/-x.xx K" for
one or more segments in the program, the duration of
the program cannot be determined.
Press and turn the knob (J) to display the segment de-
tails.
Cancel: Cancels the process.
Note: Once the program has been started, the program
no., segment no. (active/total) and the remaining dura-
tion of the segment or hysteresis are displayed in the
graph.
MODULES:
In "Modules" the multifunction connection (19) out-
puts and inputs can be configured.
The outputs M1 and M2 can be controlled via "PRO-
GRAMS".
M1-Valve:
An output to control an external valve, which can be
built into the external pump circuit or the cooling coil
inlet, for example.
ON:
Switches the external valve to the active state (inverted
initial state).
