On the manager: The manager switches the group's operating mode depending on
the window contact state. The operating mode returns to Comfort when the window
is closed.
The window contact state is provided via either local input or bus. When the
thermostat receives information from both sources, the local input takes priority.
On the subordinate: Only the subordinate connected to the local window contact
switches the operating mode to Protection when the window contact is active. The
subordinate does not synchronize the manager's operating mode until the window
is closed.
The subordinate does not receive window states from the bus.
Only the presence detector on the manager (external or built-in) controls the M/S -
manager/subordinate loop accordingly.
Presence detection on local input takes priority.
The M/S - manager/subordinate is configured via ETS/ACS or Siemens
smartphone application PCT Go.
Basic setting
Set the thermostat as subordinate: (Default parameter setting is manager.)
●
Set subordinate: P258 = 0 (subordinate)
●
Set subordinate identification number (P259 = 1...9) to send alarm information
to the manager.
●
Set manager/subordinate devices in the same zone via Geographical zone
apartment (P901) and room (P902)
Advance setting
●
To always display the Comfort setpoint, set P008 = 1 on manager and
subordinates.
●
If the setpoint (P010) of the manager is set to "save energy", the subordinate
needs to be set the same.
●
The setpoint limitation range (P013 to P016) of the subordinate can be smaller
than the limitation of the manager if requested.
●
Together with the Synco devices, set the distribution zone heating / cooling as
needed (P903 to P905)
