13.2 Working with internal or external control sensors
The internal control sensor is an immovable fixture. Any
commercially available Pt100 sensor equipped with 4-wire
technology can be used as the external sensor. For connect-
ing up see chapter
17.
The circulator must be switched off and on again after insert-
ing an external sensor. The function EXTERNAL is other-
wise not selectable. The unit switches automatically back to
the function INTERNAL.
c!l Select CONTROL, then INT-EXT and choose if you
want to work in the INTERNAL or EXTERNAL mode (or
in the "FOLGEREG" mode).
Three different control speeds are selectable in the EXTER-
NAL mode.
@ Select CONFIG -.. SETUP-2 -+ DYNAM.EX
The
unit is preset to the control speed STANDARD. Over-
swinging is thus avoided for the most part. The time until the
desired temperature has been reached can however be
quite long. If you would like to shorten this, select MEDIUM
or FAST. When using the setting FAST you should reckon
with quicker control times. The setting
MEDIUM results in
moderate overswinging and medium control speeds. The
level of overswinging is dependent on a number of factors
such as the volume of the external system. the heat transfer
liquid used, hose length, the working temperature and many
others. No general statements can thus be made at this
point.
"FOLGEREG" mode: temperature control is depending on
the measured temperature at the external sensor.
*To activate this menu the menu key has to be pressed while
switching on the unit until the first display message appears.
13.3 Working with or without cooling
You should decide if the usage of the cooling aggregate (if
fitted) is necessary depending on the desired set tempera-
ture.
Select CONTROL and then COOLING.
Switch the cooling aggregate ON or OFF.
The crossed-out star is on when the cooling unit is off.
When
chosing COOLING
ON the complete cooling capacity
is available for the cooling unit
of the C25. All the other units
are cooling controlled.
When switching shortly between ON and
OFF the cooling
unit of the
C35 will start only with a delay of 3 minutes. Atimer
in the display will show the timing.
