Technical Manual Glass Room Temp. Contr. SCN-RT1Gx.01
The following diagrams shall illustrate the connection between guiding and setpoint:
(Xsetpoint=new setpoint; Xbasic=basic comfort setpoint)
Figure 16: Example Guiding decrement
The communication object for the guiding value must be connected to the external measured
temperature. Through this object, the guiding becomes the reference value for the guiding process.
The following chart shows the relevant communication objects:

Example for the usage:
For the temperature regulation of a room, the setpoint (22°C) shall be increased in a way that at a
measured outside temperature range of 28°C to 38°C, the difference of the temperature outside and
inside is never more than 6K.
The following settings must be done at the controller:
Basics Comfort setpoint: 22°C
Guiding: active
Guising value minimum: 28 °C
Guiding value maximum: 38°C
Setpoint variation at maximum guiding
If the temperature outside increase to value of 32°C now, the setpoint will be increased by the
following value:
X = 10°C * [(32°C-28°C)/(38°C–28°C)] = 4°C
So we would have a new setpoint of 22°C+4°C = 26°C.
If the outside temperature reaches the adjusted maximum of 38°C, the setpoint will be 32°C and
behave this value even if the temperature would continue to rise.
