When MultiTemp III is switched on, the compressor starts
and the heater will be activated if the set temperature is grea-
ter then the actual temperature. A constantly lit dot in the
left digit position (9 in Fig. 2) indicates that the heater is
working to reach the set temperature. A flashing dot indica-
tes that the bath has reached the set temperature.
Note: Setting a temperature limit is important for the safe
operation of the unit. It does not set the working tem-
perature.
Set the temperature limit using the dial on the
rear of the unit. The scale shows approximate
temperatures. Set the dial to a value 5-10 °C
above the desired working temperature.
If a more accurate temperature limit is required, the procedu-
re described in Section 7.4 should be followed.
The range of temperatures that can be set can be limited if
required by the application or for other reasons.
Caution: This is a setting limitation, not a primary safety
measure. The temperature limit protection must be set sepa-
rately (see Section 4.2).
