Key: Auto means: “changes to Auto”
1) Comfort mode is operative for the pre-defined Temporary Comfort period (see page
143). The room controller then reverts to Economy.
5.6.4 Stand-alone Example
The example below shows how local influences interact to affect the room operating
mode.
• Window contacts are fitted in all rooms.
When the window is opened (1), the room operating mode changes to Protection,
and the room unit is switched to
.
• Room 1 has a room unit.
As no presence detector is connected, the basic room operation mode is Precomfort;
therefore, the timer (Temporary Comfort period: see page 143) is not available.
The room unit can be used to switch the room operating mode between Comfort and
Precomfort (2).
• Room 2 has a presence detector and a room unit..
If the room is unoccupied, the basic room operation mode is Economy. If it changes
to occupied, the room operating mode becomes Comfort (3), and the room unit is
switched to Auto.
The room unit can be used to switch between Comfort and Precomfort (2).
• Room 3: In order to force the basic room operation mode to be Economy, one of the
open Digital inputs is parameterized as Occupied = Contact closed (see page 142),
thus simulating a presence detector in state "unoccupied.
Starting from Economy, the timer (Temporary Comfort period: see page 143) is
available.
The room has a room unit with the timer enabled. It can be used to set the room
operating mode to Comfort (2). It reverts to Economy when the window is opened,
(3) when the timer period expires (4), or when the
/Auto switch is pressed again
(5).
