9. Time programs
The MB2 program controller permits programming time programs with real-time reference. It offers 25
program memory positions with up to 100 program sections each.
For each program section you can enter set-points for temperature, CO

, O

(chamber with O

control), and
humidity (CBF / CBF-UL), section duration, type of set-point transition (ramp or step) and the tolerance
ranges.
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).
Programming remains saved in case of a power failure or after turning off the unit.
