3.3.2 Setting and readjusting setpoints
Room temperature setpoints can be …
– set during commissioning,
– readjusted 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 temperature control)
1)
Only required for heating AND cooling applications (see section 3.6.9)
2) The shift is added to the local shift (LTE-Mode only)
3) The last intervention wins, either S-Mode input or local operation
4)
To display the S-Mode objects of the Economy heating and cooling setpoint (P11, P12), set the
control parameter "Room temperature: Economy setpoints" to
as group object
in the ETS tool
The current setpoint (used by the thermostat for temperature control) is available
on the bus for use in the central control unit.
