Cooling value
The cooling value can be specified here according
to the cooling mode (absolute, relative, time)
selected with step 210 [27].
• Absolute: The cycle ends if the "cooling tem-
perature" falls below the set value (in °C).
50°C to maximum temper-
ature (step 206 [23])
• Relative: The cycle ends if the "cooling tempera-
ture" falls below the set percentage value,
whereby 100% corresponds to the specified set
point (step 101 [1]).
40%…100%
• Time: The cycle ends when the set "cooling time"
in seconds has elapsed. The current cooling
value is indicated in the home position.
This function can only be selected if time control
(step 209 [26]) is active.

Hold mode
If the "Hold" function is activated, the last measured
value at the end of the heating phase is stored and
displayed.
The "ACT" (actual value) information in the home
position is replaced by "Hold". This procedure is
repeated for every cycle and the displayed value is
updated. The word "Hold" is invisible for 100ms
before the value is updated.
If you select the "2 second hold" function, the dis-
play changes back from hold mode to the actual
value in real time after 2 seconds. The hold function
is then activated again for 2 seconds at the end of
the next cycle.

Autocal
The AUTOCAL function matches the controller to
the current and voltage signals that are present in
the system.
The required calibration temperature can be set
with the "UP" and "DOWN" keys. Pressing the
"ENTER" key stores the set value and starts the
"AUTOCAL" function.
The word "- Calibration -" appears on the display
while the AUTOCAL function is executing and a
counter counts down from 15 to 0. When the con-
troller has been calibrated successfully, the display
switches back directly to the home position pro-
viding the "AUTOCOMP" function is deactivated. If
"AUTOCOMP" is active, the display jumps to
step 108.
If the controller cannot be calibrated, the AUTOCAL
function is aborted and an error message is dis-
played instead.
