1.1 Operation
For operation and display functions, Cheops control is fitted with 5 LEDs, a blue and a red
button. The top 3 LEDs are red, the bottom 2 LEDs are blue.
The LEDs show the set point temperature, i.e. the desired room temperature.
The middle LED illuminates when the temperature determined by the Basic set point value
has been reached.
The 2 buttons can be used to adapt the set point value to suit the individual requirements of
the room user.
Pushing the red button increases the set point value by one programmed increment, this is
possible twice from the basic set point value (middle LED).
Pushing the blue button reduces the set point value by increments.
If Cheops control is not in comfort mode, or if the set point value has already been decreased
by 2 increments from the basic set point value, the bottom LED illuminates.
This indicates to the room user that the set point value cannot be further decreased.
When the red button is pushed, Cheops control automatically finds the correct function that
increases the set point value - this depends on the operating mode prior to the button being
pushed:

In comfort mode, the set point value can now be changed in increments as usual.
If the blue button is pressed until the bottom blue LED illuminates, the presence object is reset
and the original operating mode is restored.
