(3) Forced control AUTO (Control bit = 1, Value bit =0). Normal detector operation is resumed.
Disable object
Input
-
1 Bit
In this setting, the object can receive two values (1 - bit command).
The reaction of the device at the reception of both of these values can be selected through parameters “ If
disabled object = 0” and “ If disabled object = 1” (under the menu “Light”).
Both events can be associated to any one of following actions:
•
Forced control ON
•
Forced control OFF
•
Automatic
•
Lock (current switching state)
•
No action
Warning: in case of wrong parameter setting (e.g. “Lock” associated to value 0, “No action”
associated to value 1, and General / Delay time for forced control mode set to OFF), the
device can enter a lockdown state which can only be recovered by reprogramming.

HVAC control channel
The HVAC control channel has the same communication objects as the Lighting channel and works exactly
in the same way;
The HVAC channel has the same operating modes and communication objects as the lighting channel; the
normal detection of movement and presence is replaced by a “long duration” detection.
Long duration detection is based on several time windows (from 2 up to 20) of equal width; in every one of
these windows at least one movement must be detected in order to yield a positive response. The number
and (common) duration of these time windows can be configured through the respective parameters. The
total time required for a positive detection is the product of the selected number of windows by their duration.
Presence function
The HVAC channel can be used to detect the occupancy of the monitored area. To this purpose, the number
of windows should be set to 1 and the duration should be set to 1 s.
Operation of the HVAC channel is independent from ambient brightness.

Object 4 Output
–
HVAC (switching)
–
Switch
 Output - 1 Bit
Object 4 Output – HVAC (switching) – Switch is similar to Object 0 Output – Light – Scene , but it has several
additional features (see also HVAC Parameters in section 6.1).
6.2.2 Object 5 External switch / status – HVAC - Switch
Input - 1 Bit
Object 5 External switch / status – HVAC - Switch behaves the same as Object 1 External switch / status –
light – Switch .
