Building Technologies Setpoint calculation 21 Sep 2010
HandyTool See the parameters in the last column of the following table.
Name Basic setting Range 1) Resolution Parameter
Protection cooling setpoint 40 °C 10 ... 40 °C 0.5 K *030
Economy cooling setpoint 35 °C 10 ... 40 °C 0.5 K *031
Precomfort cooling setpoint 28 °C 10 ... 40 °C 0.5 K *032
Comfort cooling setpoint 24 °C 10 ... 40 °C 0.5 K *033
Comfort heating setpoint 21 °C 10 ... 40 °C 0.5 K *034
Precomfort heating setpoint 19 °C 10 ... 40 °C 0.5 K *035
Economy heating setpoint 15 °C 10 ... 40 °C 0.5 K *036
Protection heating setpoint 12 °C 10 ... 40 °C 0.5 K *037
1) ACS checks the values / ranges for intersection.
There is no check in ETS and HandyTool.
HandyTool: If setpoints are irrelevant for the application (e.g. heating setpoints for
chilled ceiling), they are hidden, and they are set equal to the Protection setpoints
internally.
For reasons of symmetry, all communication objects are always available.
6.3 Setpoint setting runtime
The setpoints are stored in the EEPROM so that they are retained upon a reset. If the
communication objects
Setpoints heating and Setpoints cooling receive a value
different from the previous value, this is written to the EEPROM. The service life of the
EEPROM depends on the number of write cycles.
The setpoints for
Comfort, Precomfort, and Economy, for heating and cooling each, can
also be defined during runtime
as individual values or triplets via the bus.
