Press key
Display 1 shows e.g. 37.0
(actual temperature set-point 2)
(visible only if week program timer is activated
in the user level, chap. 10)
Display 2 shows SP2 TEMPERATURE (variable: temperature in °C)
Enter temperature set-point in °C using
arrow keys
Value is shown in display 1.
Press key
Display 1 shows e.g. 100 (actual fan speed set-point)
Display 2 shows SP FAN SPEED (variable: fan speed in %)
Enter fan speed set-point in % using arrow
keys
Value is shown in display 1.
Press key
Only with option zero-voltage relay outputs via operation lines (chap. 16.4):
Display 1 shows e.g. 000 (actual switching state of operation lines)
Display 2 shows OPERATION LINE (variable: switching state of operation lines)
Enter switching state using arrow keys
Display 1 shows e.g. 40 (actually set safety controller set-point)
Display 2 shows SP SAFETY CONTR. (variable: safety controller set-point)
Set safety controller class 3.1 set-point in °C
using arrow keys
Note setting “limit” or “offset” selected at the
user level (chap. 10)!
Value is shown in display 1.
Press key
If no button is pressed within more than 120 sec, or if the EXIT button is pressed, the controller changes
to Normal Display.
When changing the set-point, check the safety controller setting in the user level (chap. 10) if
the safety controller has been set to “limit” mode.
If the fan is operated with less than 100 % speed, the temperature performance and the spatial
exactitude of the temperature can differ from the manufacturer’s specifications. Do reduce the
fan speed only if absolutely necessary due to special requirements.
The cooling power decreases when the fan speed is reduced to 20% or below.
The values entered in fixed-value entry mode remain valid after program run-off and are then
equilibrated.
If the week program timer is active, depending on the running week program another set-point (SP2) may
be targeted. Too high or too low temperatures can occur which exceed the permissible temperature of the
charging material. Deactivate the week program timer if you do not use it (default setting, setting in the
User level, chap. 10).
