9.6 Information on programming different temperature or humidity transitions
• For the end value of the desired cycle, add an additional section (in the examples section 05 for “set-
point ramp” and section 08 for “set-point step”) with a section time of at least one second. Otherwise,
the program will stop one section too early because the program line is incomplete.
• When operating without humidity (humidity switch (4) OFF), enter a humidity sub-program with the
humidity set-point set to “0” to avoid alarms (in case the humidity deviates by more than +/- 5% from
the set-point).
• Program interruption (rest function): Hit key "HAND" in order to interrupt the program. During this
program interruption time the controller equilibrates to the set-points of the section actually reached.
• The display reads “AUTO HAND” on the bottom right instead of “AUTO” (program operation). This
state lasts until you hit the “EXIT” key, then the program continues. If you want to cancel the interrupted
program, keep the “AUTOMATIC” button pressed down for at least 5 seconds.
• Tolerance band function: If the tolerance minimum is set to e.g. -5 and the tolerance maximum to
e.g. +5, the program is interrupted when the actual value deviates by 5 °C resp. 5 % r.H. or more from
the “set-point” value. During this program interruption time the controller equilibrates to the set-points of
the section actually reached. The display reads “AUTO HAND” on the bottom right instead of “AUTO”
(program operation). You can enter different values for tolerance maximum and minimum for each sec-
tion. When the temperature or humidity are situated within the entered tolerance limits, the program is
automatically continued, and the indication “AUTO HAND” disappears. If you want to cancel the inter-
rupted program, keep the “AUTOMATIC” button pressed down for at least 5 seconds.
Programming of tolerances can extend program duration.
The number -1999 for the tolerance minimum means “-∞“ and the number 9999 for the tolerance max-
imum means “+ ∞“. Entry of these numbers will never lead to program interruption.
When leaving the tolerance bandwidth in one of the subroutines, the course of time of the whole pro-
gram, i.e., of both subroutines, is halted.
During the rapid transition phase, do NOT program any tolerance limits in order to permit the maximum
heating, refrigerating, or humidification speed.
• The initial setting ∗∗∗∗.∗ of the fan speed corresponds to the maximal speed of 100 %.
Do reduce the fan speed rate “ONLY” if it’s absolutely necessary for the essay. Usually,
the spatial exactitude of temperature and of humidity decreases with lesser ventilation.
Technical data refers to a 100 % fan speed rate.
• Programming is stored even in case of power failure or after turning off the unit.
• The controller memory can store a maximum of 25 programs. Each program cannot exceed 100 sec-
tions. It is not possible to link programs. The total number of program sections of all programs is limited
to a maximum of 500.
• Running program (display AUTO): If you incidentally press the “EXIT” or “AUTOMATIC” button, the
controller will change to Idle Mode and thus will not adjust any longer to the program set-points
• Program interruption with rest function (display AUTO HAND): If you press the “EXIT” key, the program
continues. Button “ENTER” is non-functional. To cancel the program, keep the “AUTOMATIC” button
pressed down for at least 5 seconds.
• Program interruption with tolerance band function (display AUTO HAND): Buttons EXIT and ENTER
are non-functional. To cancel the program, keep the AUTOMATIC button pressed down for 5 seconds.
General note:
The controller MB1 displays more menu entries than those described in this manual. These are password
protected because they are relevant for service purposes only and the user must not modify them. Only
service authorized by BINDER can access these entries.
