Figure 6: RD3 program controller
The program controller RD3 allows programming of temperature cycles. For each program section also
the fan speed can be regulated.
Two programs with up to 10 sections each or one program with up to 20 sections can be entered (setting
in the user level, chap. 10).
When changing from 2 programs to 1 program or vice-versa, existing programs are deleted
The maximum length of an individual program section can be set to either 99 hs 59 min or to 999 hs 59
min (setting in the user level, chap. 10). This setting is then valid for all program sections.
Programming can be done directly via the controller keyboard or graphically at the computer using the
software APT-COM™ 3 DataControlSystem (option, chap. 15.1) specially developed by BINDER.
