WARNING display:
A warning does not result in shutdown of the heater, refrigeration
unit, and circulation pump.
The unit provides the option of defining some warning limits
independently, such as limits for pump pressure, limits for over-
temperature and under-temperature.
If one of these limits is exceeded, a warning (ticker and signal) will
continue for as long as the cause is active.
The yellow attention symbol will remain. It will draw attention
to events that occurred during absence of the operating personnel.
The events are stored in a list of errors.

Note:
The temperature system has been configured and supplied by
JULABO according to N.A.M.U.R. recommendations. This means
for the start mode, that the unit must enter a safe operating state
after a power failure (non-automatic start mode). This safe
operating state is indicated by "OFF", on the TFT-Display. A
complete shutdown of the main functional elements such as heater
and circulation pump is effected simultaneously.
Using the AUTOSTART function is only possible when a set-point
is set via >TFT Display< and >EPROG-input<.
Should such a safety standard not be required, the AUTOSTART
function (automatic start mode) may be activated, thus allowing the
start of the instrument directly by pressing the mains power switch
or using a timer.
