● Manager and subordinates can be bound as one group via setting their
geographical zone (apart.) P901 and geographical zone (room) P902 to same
value.
● Synchronization works even if the manager and subordinate are different
products or set with different applications.
● The thermostat can be set as subordinate via parameter P258 and each
subordinate can be identified via one identification number (P259). The
identification is relevant with alarm management between subordinate and
manager.
● When the thermostat is set as subordinate, the HMI is locked and users cannot
operate the thermostat locally. At the same time, some parameters are invisible
and non-accessible for setting (see Control parameters [➙ 138]).
● Fan state and setting of M/S - manager/subordinate are independent. The fan
state depends on the fan setting of each device, i.e., manager and subordinate
can display different fan speeds.
● All M/S - manager/subordinate settings are set via mobile app PCT Go, KNX
tools ETS, Synco ACS or locally on the HMI (parameter setting mode).
● Alarm indication: All active subordinate alarms, e.g. condensation alarm, are
displayed on the subordinate. At the same time only the higher priority alarm
(see Alarm management manager/subordinate [➙ 67]) is displayed on the
manager with subordinate identification number. This function is available only
when a subordinate identification number is set from 1 to 9. If the identification
number is set to Off, the subordinate does not send alarms to the manager.
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.
