In "Ctrl�Mode Ramp", allows even heating with a defined
gradient� The segment is completed after the target tem-
perature has been reached�
The slope in K/min is determined by the quotient of the
temperature difference and the time specified in the cur-
rent segment "Time hh: mm"�
The temperature difference is calculated from the set
point temperatures of the current and previous segments�
Note: The ramp function can only be selected from the
second segment�
5) Pump rpm: Target speed of pump�
6) 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"�
7) 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 M2-Output-Switch" in "Default Sta-
tus" as "Open" or "Closed"�
Delete: Deletes the selection highlighted in yellow (seg-
ment or program)�
Edit: Edit/change program parameters�
Delete: Delete program segment�
Insert: Inserts a new program segment after the se-
lected segment�
Save: Saves changes�
3. Delete:
Deletes the selected yellow background program�
OK: Confirm the process�
Cancel: Cancels the process�
4. View:
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 details�
Once the program has been started, the program no�,
segment no� (active/total) and the remaining duration
of the segment or hysteresis are displayed in the graph�
MODULES:
In "Modules" the multifunction connection (18) outputs
and inputs can be configured�
The outputs M1 and M2 can be controlled via "PRO-
GRAMS"�
1. 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�
1) ON:
Switches the external valve to the active state (inverted
initial state)�
Note: In started "Program", the M1 segment settings
have higher priority�
2) Default Status:
Defines the default state (OFF) of the external valve as
"Open" or "Closed"� It depends on the valve type (nor-
mally open or closed)�
3) Refill:
Uses the external M1 valve to automatically check the
level when operating with water�
Observe "Default Status" setting�
Start: Sets the valve switch-on point (ON)�
Stop: Sets the valve switch-off point (OFF)�
Note: Prior to using the "Refill" option check the func-
tion of the buoyage (4)�
The "Refill" option has higher priority than the program
M1 segment settings�
4) Temperature:
Temperature-dependent control of the M1-valve�
By entering the boundaries of “Higher” and “Low”, the
temperature range is set in which the M1-valve can be
opened�
If you activate a rule “Int / ext> Set Temperature” is an
automatic control of the M1-valve dependence on the
target temperature�
By the “Hysteresis” value (set temperature hysteresis) the
control stability can be optimized�
Note: int / ext stands according to the selected control
mode (internal (int) or external (ext)) for the actual tem-
perature to be controlled�
2. M2-Output:
1) Alarm:
Activates the alarm output (switch contact)�
Error: In the event of an error the "M2-Output —
Switch" is activated (ON, inverted initial state)�
Warning: In the event of a warning the "M2-Output —
Switch" is activated (ON, inverted initial state)
When "Warning" is activated, "Error" is simultaneously
activated�
