Example for stand-alone

The example below shows how local influences interact to affect the room operating
mode.
• Window contacts are installed in all rooms .
If the window is opened (1), the room operating mode changes to Protection and the
room unit is switched again to
• Room 1 has a room unit .
As no presence detector is connected, the basic room operating mode is Precomfort
and the timer (Temporary Comfort mode time, see page 103) is thus not available.
The room unit allows for switching between Precomfort and Comfort (2).
• Room 2 has a room unit and a presence detector .
If unoccupied, the basic room operating mode is Economy ; if occupied, the room
operating mode changes to Comfort (3) and the room unit is set to Auto.
The room unit allows for switching between Comfort and Precomfort (2).
• Room 3 : To force the basic room operating mode Economy , a presence detector in
state unoccupied is simulated at an open digital input (occupied = contact closed,
see page 102).
The timer is available from Economy .
The room has a room unit on which the timer is activated ( Temporary Comfort
mode period: see page 103). This is where the room operating mode is set to
Comfort (2); when the window is opened (3), after timer expiration (4), or after
pressing again the
/Auto button (5), the room operating mode returns to Economy .
