4.6.8.2 Manager/subordinate communication in LTE-Mode
The manager thermostat shares the configuration with its subordinates for the
following:
● Room temperature and humidity value
● Operating mode
● Manual fan speed
● Current room setpoint and ChangeOverWaterStatus
If any of the above values is changed on the manager, the change is synchronized
to all subordinates within the same zone. For M/S - manager / subordinate
configuration, see M/S, Manager/subordinate configuration in LTE-Mode [➙ 123].
After initial power-on, without changes on the HMI, synchronization between
manager and subordinate may take up to 15 min.
Every change on the manager HMI, e.g. setpoint, op. mode, etc, is immediately
sent and updated on the subordinate.
A heartbeat function communicates between manager and subordinate objects.
The function ensures that information is synchronized and correct between
manager and subordinates. See Send heartbeat and receive timeout [➙ 126].

configuration in KNX S-Mode [➙ 118].
