Peltier  technology  for continuously adjustable heating and cooling down. A multifunctional, fuzzy-supported PID process controller, with permanent performance adjustments and integrated self-diagnosis system, ensures perfect and absolutely reliable temperature control and the highest process safety.

• Temperature range 5 °C to 60 °C with a display and setting accuracy of 0.1 °C
• Over and under temperature protection: An adjustable over/under temperature controller TWW protection class 3.3 (optional adjustable electronic temperature limiter TWB protection class 2) takes over control in case of failure  at a preset temperature. ASF Automatic Safety Function - a unique safety function - for over- and undertemperature automatically following the setpoint in a freely selectable tolerance range. An alarm sound is activated in case of over- /undertemperature, and the heating function is switched off in case of overtemperature, cooling function is switched off in case of undertemperature.
• 2 high-grade platinum temperature sensors Pt 100 in a 4-wire circuit (for stable long-term transmission of measurement signals) communicate with each other and ensure uninterrupted error-free temperature control at constant working temperature
• Digital programme control (programmable to the minute) for temperature profiles consisting of up to 40 ramps
• Weekly timer programmable to the minute
• Simultaneous display of all parameters, such as  temperature, weekday, time, and number of ramps
• Visual and acoustic alarm in case of over-/undertemperature
• Alphanumeric text display in different languages (D/UK/E/F/I)
• Function signals for stand-by, operating mode, heating, cooling and malfunction over/undertemperature
• Internal log memory with 1024kB to save temperature and error states, with timestamp to the minute
• Chip card control including 1 MEMoryCard XL with 32 kB memory capacity (max. 40 ramps)
• Serial  RS-232 communication interface and software Celsius 2007 to read out the appliance's internal log memory
• Parallel printer interface for printout of log data via an external PCL3-compatible inkjet printer
