Timer Digital backwards counter with target time setting, adjustable from 1 minute to 99 days
Function SetpointWAIT the process time does not start until the set temperature is reached
Calibration three freely selectable values each, temperature/humidity, for two freely selectable values CO2
adjustable parameters temperature (Celsius or Fahrenheit), fan speed, CO2, programme time, time zones, summertime/wintertime

Ventilation

Fan forced air circulation in working chamber adjustable from 10 to 100 % in 10 % steps, fixed value 50 % when working with CO2

Communication

Documentation programme stored in case of power failure
Programming AtmoCONTROL software on a USB stick for programming, managing and transferring programmes via Ethernet interface or USB port

Safety

Temperature control mechanical temperature limiter TB, protection class 1 according to DIN 12880 to switch off the heating approx. 10°C above nominal temperature
Temperature control over- and undertemperature monitor TWW, protection class 3.3 or adjustable temperature limiter TWB, protection class 2, selectable on display
AutoSAFETY additionally integrated over- and undertemperature protection “ASF”, automatically following the setpoint value at a preset tolerance range, alarm in case of over- or undertemperature, heating is switched off in case of overtemperature, compressor in case of undertemperature
Autodiagnostic system integral fault diagnostics for temperature, CO2 and humidity control
Alarm visual and acoustic

Heating concept

Air jacket air jacket heating system for gentle all-around heating
Heating concept no drying-up of the load caused by the cooling device due to separation of thermal jacket from interior
Cooling energy-saving use of CFC-free cooling/heating system (refrigerant R134a)
Defrosting highly efficient automatic defrosting system
