The 2-channel program controller MB1 controls the following values inside the alternating climate cham-
ber:
•
Channel 1: Temperature in °C. Range without humidity: -40 °C / -40°F up to 180 °C / 356°F,
in climatic operation: +10 °C / 50°F up to +95 °C / 203°F.
• Channel 2: Relative humidity in % r.H. Range 10 % r.H. to 98 % r.H.
You can enter the desired set point values in Manual Mode or Program Mode (chap. 5.2) on the display
controller. For the control range of temperature and relative humidity, see chap. 14.

5.2 Operating modes
The 2-channel program controller MB1 operates in 3 modes:
Idle Mode The controller is not functional, i.e., there is no heating or refrigeration and
no humidification. The fan is off.
Manual Mode
(Fixed value operation)
(HAND)
The controller operates as a fixed-point control, i.e., set-points for tempera-
ture and humidity can be defined, which are then maintained (chap. 8).
Program Mode (AUTO) An entered temperature and humidity program is run (chap. 9).
The 2-channel program controller MB1 permits programming temperature and humidity cycles.
The controller offers 25 program memory positions with 100 program sections each. The total number of
program sections of all programs is limited to 500.
Programming can be done directly through the keypad of the controller or graphically through the soft-
ware APT-COM™ 3 DataControlSystem (option, chap. 16.1) specially developed by BINDER.
5.3 Behavior after power failure
After power returns, the unit continues to function in the original operating mode it was in previously be-
fore an actual power failure had occurred. In Manual Mode (HAND), the controller regulates temperature
and humidity to the last entered set-points, while in Program Mode (AUTO) it regulates temperature and
humidity to their set-points that were reached during the program operation. The power failure is noted in
the event list (chap. 6.2) however, no error message is displayed indicating that a power failure has taken
place.
5.4 Behavior when opening the door
When you open the door, temperature control (heating and refrigeration) immediately stops (the com-
pressor continues running for 5 minutes without cooling). Humidification and dehumidification are off. The
fan is off.
