| Controller | Electronic microprocessor temperature controller with auto-diagnostic system |
| Controller | digital display of all set parameters, such as temperature, weekdays, time, fan speed, programme status and set-up values |
| Timer | integrated timer for tempering profiles of up to 40 ramps each, each segment adjustable from 1 min. to 999 hrs. |
| Timer | digital 7-day programme timer with real time clock, precise minute setting, for one set value or start of ramp operation |
Temperature
| Set temperature range in °C | min.10°C above ambient up to +300°C |
|---|---|
| resolution of display for actual values | 0.1°C |
| resolution of display for setpoint values | 0.1°C up to 99.9°C, 0.5°C from 100°C |
| resolution of display/setting accuracy | 0.5°C up to 99.9°C, 1°C from 100°C |
Ventilation
| Fan | forced air circulation by quite air turbine, adjustable in 10 % steps for each segment individually |
|---|---|
| Fresh air admixture | adjustment of pre-heated fresh air admixture by air flap control in 10 % steps for each segment individually |
