1) ACS checks the values / ranges for intersection.
There is no check in ETS and HandyTool.
2) The Frost protection limit can only be changed in applications with an outside air
damper. In the other applications it is fixed at 5°C.
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 adjustment runtime
The setpoints are stored in the EEPROM so that they are retained when the controller
is reset.
Separate heating and cooling setpoints for Comfort, Precomfort and Economy may also
be defined via the bus, either individually or as triplets.
