9. Time programs
The MB2 program controller permits programming time programs with real-time reference. It offers 25 pro-
gram memory positions with up to 100 program sections each.
For each program section you can enter a temperature set-point, fan speed (with MK 56), section duration,
type of temperature transition (ramp or step) and the tolerance range.
If the safety controller has been set to “limit” mode, check the setting of the safety controller
when changing the temperature set-point, (chap. 12.2).
MK 56: Reduce the fan speed only if required, because the spatial temperature distribution
will also be reduced.
Technical data refers to 100% fan speed.
Programming remains saved in case of a power failure or after turning off the unit.
