Building Technologies Setpoint calculation 21 Sep 2010
In LTE-mode, the central setpoint setting is transmitted via the following communication

Setpoints changed by a tool (e.g. HandyTool) are overwritten by PX-KNX during room
controller startup!
6.4 Central setpoint shift
The Comfort, Economy and Precomfort setpoints can be adjusted separately for
heating and cooling centrally from the BACS.
Central setpoint shifts are used particularly e.g. for summer/winter compensation.
Summer/winter compensation causes a gradual increase in room temperature as a
function of the outside temperature. This prevents too great a difference between the
indoor and outdoor temperature in summer and increases overall comfort in winter.
Normally, only Comfort and Precomfort values are shifted.
The room controller corrects the setpoints resulting from central shift by applying the
following rules
Comfort setpoints:
The value for the spacing must not be below the original value
A
.
Precomfort setpoints:
The value for the spacing to Comfort setpoints must not be below the original values
B
.
