Special application modes
In W0202 module simple applications have been built which can be used to control building
devices. The applications make logic between signal from Special Input and control Digital
Output state. Relation between Inputs and Outputs is shown in the table below and it cannot be
changed.

The Special Inputs can be set to work in different modes. There are dedicated registers for
operation mode (40176, 40180), time parameters (40177, 40181), setpoints for heating/cooling
modes (40178, 40182), and for differential value in heating/cooling modes (40179, 40183).
