6.9  Safety thermostat 

When the bath temperature becomes higher than the set 
point temperature of the safety thermostat (Indicated as 
7, see page 14), the heating electronics and controller are 
switched-off. The red LED on the display will light. When 
the  temperature  of  the  bath  has  been  lowered  with 
approximately  10°C,  the  thermostat  re-sets  itself 
automatically, however to continue normal operation the 
bath has to be switched off and on again.  

 

 

Use well grounded mains. Before plugging the TV12 into  the mains socket, make sure the voltage of the bath 
corresponds to the local voltage.
