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 (3) 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 interrupt-
ed 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
section. When the temperature or humidity are situated within the entered tolerance limits, the pro-
gram is automatically continued, and the indication “AUTOHAND” disappears. If you want to cancel
the interrupted 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 maxi-
mum 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. Tech-
nical 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 lim-
ited 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 pro-
gram 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
at least 5 seconds.
General note:
The MB1 controller 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.
