5.2 Operating modes
The MB1 2-channel program controller operates in 3 modes:
Idle Mode
The controller is not functional, i.e., there is no heating or refrigeration
and no humidification or dehumidification. The fan turns at a 50% rate.
Manual Mode
(Fixed value operation)
(HAND)
The controller operates as a fixed-point control, i.e., set-points for
temperature 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 MB1 program controller 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. 14.1) specially developed by BINDER.
5.3 Performance after power failures
After the power returns, the unit continues to function in the original operating mode it was in previously
before an actual power failure had occurred. In Manual Mode (HAND), the controller regulates tempera-
ture 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.
