7.4 Digital Outputs Registers
7.4.1 State of Digital Outputs (40018)
The register contains the state of digital outputs. Setting true value of particular bit
activates assigned output according to the following table:
No. of Bit in Register
No. of Digital Output
0
1
1
2
Table 24. State of Digital Outputs register values
7.4.2 Default State of Digital Outputs (40143)
The register contain the default states of digital outputs after power up or watchdog
reset. Particular bits with assigned digital outputs are shown in the table:
No. of Bit in Register
No. of Digital Output
0

7.5 Special Application Modes
In the iSMA-B-W0202 module, simple applications are built-in, which can be used to
control building devices. The applications provide logic between a signal from the special
inputs and control digital
output’s
state. Relation between inputs and outputs is shown in
the table below and it cannot be changed.

Table 26. Built-in application determines relations between inputs and outputs
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 a differential value in heating/cooling modes
(40179, 40183).
