TIMER (Multiple Switchings), consists of 11 forms. A main form, 8 output forms, 1 inputs form and a settings form. The main form gives the status of all 8 outputs and 5 inputs. The location of each output and input can be altered on this form.

Each output form can be selected by the push-buttons marked 1 to 8 or the inputs can be selected by the push-button Inputs.

The main form can be minimized so that the user can do other tasks, and the timing program will still run in the background.

All output forms can be in ON, OFF or AUTO modes. When in AUTO the output will be on or off depending on the times selected.

All outputs (channels) can have up to 10 switching times within the 24hr period from 00:00:00 to 23:59:59.All outputs have an additional pulse timer from 1 second to 24 hours (set in minutes), on or off.
