Excess temperature protection 

 
 
 
 

  

 

 

 
 

 

This excess temperature protection is independent of the control 
circuit. When activated heater and circulating pump are 
completely shut down. 
The alarm is indicated by optical and audible signals (continuous 
tone) and the error message "ALARM-CODE 

14

" appears on the 

MULTI-DISPLAY (LED) 
Setting range:  20 °C ... 230 °C 

L

 

Rough setting can be effected by using the temperature scale. 

Exact setting: 

1.  Press the key 

 to display menu > tSA <.  

2. Press the 

 

key and the set shutdown value is indicated. 

Set the new shutdown value within 30 seconds using a 
screwdriver. The value is indicated on the MULTI-DISPLAY (LED)
Example: >tSA< / 100 °C 
 
Recommendation: 
Set the excess temperature protection at 5 °C to 10 °C above the 
working temperature setpoint. 

 

 

 

Warning:  

The excess temperature protection 

must

 be set at least 25 °C below the fire 

point of the bath fluid used! 
In case of wrong setting there is a fire hazard! 
We disclaim all liability for damage caused by wrong settings!
