• Immersion heater has not yet been used:
– The safety temperature limiter has been tripped by storage below -12°C.
– Set the sensor temperature to 20°C and then unlock the safety temperature limiter. (see chapter 7.1 "Unlocking the safety
temperature limiter" on page 12 )
• Immersion heater has already been used:
– The cause of the tripping of the safety temperature limiter may be damage to the immersion heater.
– Do not unlock the safety temperature limiter.
– Replace the immersion heater as a unit.
