3.3.2 Setting and adjusting setpoints
Room temperature setpoints can be
– set during commissioning
– adjusted during operation
The source can be
· the local HMI
· a tool
· a central control unit
The thermostat stores the setpoints…
· in EEPROM in the form of parameters
· in the runtime memory
The table below shows the interrelations:

Current setpoint (used by the thermostat for room temperature
control)
1)
Only required for heating and cooling applications (see section 3.6.8).
2)
LTE mode: shift is added to the local shift.
3)
S-mode: the last option selected is always used, either S-mode input or local
operation.
The current setpoint (used by the thermostat for room temperature control) is
available on the bus for use by the central control unit.
· The supported communication objects are different in LTE mode and S-mode.
· Making changes using the local HMI or tool have the same priority.
