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
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).
