14.6 Working with or without cooling
(only in combination with cooling units)
You should decide if the usage of the cooling aggregate (if
fitted) is necessary depending on the desired set tempera-
ture.
1
Select „Settings“/“Temp. setting“ 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 C25P. All the other units
are cooling controlled.
If you quickly switch between the OFF and ON or in the event
of a short mains disconnection, the refrigeration machine will
for safety reasons only start up with a 5 minute delay.
If the set temperature value is higher than 100
°
C the cool-
ing unit will not be switched on. Nevertheless, for special
applications, e. g. an expected exothermal reaction, it could
be suitable to let the cooling unit run (only partial cooling
capacity of 30% of the full capacity).
2
Select „Settings“ / „Temp. settings“, then „Cooling“ and
then Cooling-HT.
Switch to ON if the cooling unit should run (default set-
ting is OFF).
14.7 Setting temperature limit values
The setting range of the operating temperature of the circula-
tor can be limited if the application or the flash point of the
selected heat transfer liquid requires this.
This is an additional safety element to avoid error
when operating the unit. The supervision of the
temperature limits is only active when the control
is running. The excess temperature protection has
to be set separately.
When in the external control mode (for „Extern“ setting see
chapter 14.5), the limits set restrict the temperature in the cir-
culator‘s own bath in order to guarantee a higher degree of
safety against unintentional heating up or cooling down.
Select „Settings“ / „Temp. settings“ and then „LImits“. Alter
the display in same way as described in chapter 14.2.1.
First High and then Low-Limits.
The minimum and maximum limit values that can be set de-
pend on the unit combination.
