The figure below shows the interrelation:
1)
Only required for heating and cooling applications (see Setpoints and sequences
[➙ 99])
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
4)
To display the S-Mode objects of the Economy heating and cooling setpoint
(P019/P020), set the control parameter "Room temperature: Economy setpoints" to
as group object in ETS tool
5)
Other functions:
● If current humidity setpoint is not suitable for room humidity, setpoint shift is
activated via humidity control strategy (P451).
In cooling mode, a large difference between outside and indoor temperatures can
create discomfort and waste energy. The thermostat can track the outside
temperature via the bus and adjust the cooling setpoint to make sure the difference
is not too great. If the outside temperature is higher than 26 °C and 6 K above the
Comfort cooling setpoint, the related setpoint is shifted and kept 6 K below the
outside temperature. This function can be enabled or disabled via P255.
The current setpoint (used by the thermostat for temperature control) is available
on the bus for use in the central control unit.
