5. Start up
After connecting the electrical supply (chap. 4.1), turn on the chamber via the main power switch (2).
Warming chambers may release odors in the first few days after commissioning. This is not a quality de-
fect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one
day and in a well-ventilated location.

5.2 Operating modes
The program controller MB1 operates in 3 modes:
Idle Mode
The controller is not functional, i.e., there is no heating. The fan turns
at a 50% rate.
Manual Mode
(Fixed value operation) (HAND)
The controller operates as a fixed-point control, i.e., a temperature
set-point can be defined, which is then maintained (chap. 8).
Program Mode (AUTO)
An entered temperature program is run (chap. 9).
The program controller MB1 allows programming temperature 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.
