Function
The MicroRex D22 is a microprocessor controlled digital time switch. Eight programs of your choice can be stored and used to control the automatic operation of your electrical equipment. Each indi-
vidual weekday can have a separate program or you can have several days operating on the same „Block“ program. To program the MicroRex D22 a „picture“ is used and when this is complete the
chosen times are stored in the microprocessor memory. The MicroRex D22 makes available 2 separate switching channels. The summer-/winter changeover can be programmed for hand or automa-
tic operation.
