The thermostat is forced to Economy mode when ...
·
a window is open
·
a presence detector signals "no one present"
·
the keycard of a hotel room is withdrawn, etc.
The contact can be connected to digital input D1 or multifunctional input X1, X2.
Set P38, P40 or P42 to 3. P02 is not relevant. User operations are ineffective and
OFF displays if the operating mode switchover contact is active.
The thermostat is forced into Protection mode when the window is open. The
contact can be connected to multifunctional input X1, X2 or digital input D1. Set
P38, P40 or P42 to 3. User operations are ineffective and OFF displays if the
window contact is active.
The function operating mode switchover (window contact) is also available via the
KNX signal "Window state", e.g. from a KNX switch or a KNX presence detector.
·
Only one input source must be used, either local input X1/X2/D1or KNX bus.
User operations are ineffective and OFF displays if the operating mode
switchover (window contact) is active, or if "Window state" is sent via bus.
·
When RDG160KN is set as slave, the window state (as Transmit) is sent to
the master and the operating mode of all slaves will be changed accordingly,
as long as at least one window contact is open
The operating mode can be changed to Comfort or Economy mode based on the
room occupancy (room occupied or unoccupied, via presence detector or keycard).
