2524X/2525XCH
4.1.4. OBJECT 1 EXTERNAL SWITCHING / STATUS - LIGHT - SWITCH
Input 1 Bit
Input object 1 external switch / status can be used in two different ways:
• As an input for an external push button that directly switches on the light
• As an input for monitoring the status or the input of an actuator
In both cases, a received telegram „ON" sets the detector to the ON state and an „OFF" telegram to the ready state.
Whether commands for ON or OFF will be sent during the transitions depends on the parameter sending conditions for external push button.
After having received an ON command, the follow up timer starts as if a motion had been detected.
Lighting is subsequently switched off again.
After having received an OFF command the detector remains in its passive status during which it will not detect any motion. After having passed the idle time after switch off, the detector is ready again.
The idle time after switch off can be programmed in the light menu.
4.1.5. OBJECT 2 EXTERNAL MOVEMENT - LIGHT - SWITCH
Input 1 Bit
Additional detectors (slaves) can be connected through Object 2 "external movement - light – switching".
The received signal from external presence detectors is processed the same as if from its own detector and works in parallel.
Object 2 is used to set up a Master-Slave configuration as follows:
Slave devices: Connect all outputs of the slave devices (
4.1.6. OBJECT 3 INPUT - LIGHT - FORCED CONTROL / LOCK
Input 2 Bit
The meaning of this object is defined by the Light
Forced control object:
Object 3 when used as forced control object has 3 values which can be received by a 2 bit command:
1. Forced control object ON (control = 1, value = 1)
An ON command is sent unconditionally to the output – light (object 0).
The follow up timer is disabled and the timer release time starts.
If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.
2. Forced control object OFF (control = 1, value = 0)
An OFF command is sent unconditionally to the output – light (object 0).
The delay timer is disabled and the timer release time starts.
If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.
3. Forced control object auto (control = 0, value = 0)
Normal operation is resumed immediately.
Locked object:
Object 3 when used as locked object has 2 values which can be received by a 1 bit command 0 and 1:
The response to a switch command on this object is controlled by two more parameters:
Light if locked object = 0, and Light
Both parameters can specify one of the following commands:
• forced control ON
• forced control OFF
• automatic
• lock (actual state)
• do nothing
Note: Incorrect settings of parameters such as: locked object, lock at 0 and no action at 1 and release time restraint OFF can completely inactivate the correct function of the presence detector.

4.2. HVAC channel

Output 1 bit
The HVAC channel has the same objects and the same operating modes as the light channel. It works the same way as the light channel as well.
The motion detection function, however, has been expanded and substituted by a "longer presence detection". This is done by setting several equally long monitoring time windows. At least one motion
detection must occur during each time slot.
The parameters are:
• number of monitoring time windows
• length of monitoring time window (s)
Presence function
The HVAC output can be used as a presence detection. To activate this, the number of observation time windows must be set to 1 and the length of the observation time window set to 1 second. The presence
signal is independent of the ambient light level.
4.2.1. OBJECT 4 OUTPUT – HVAC – SWITCH
Output 1 bit
Object 4 "Output - HVAC - Switch" is similar to object 0 "Output - light - switch" but has additional functions (see HVAC parameters, page 10).
4.2.2. OBJECT 5 EXTERNAL SWITCHING / STATUS - HVAC
Input 1 Bit
Object 5 "External switching / status - HVAC" is identical to object 1 "External switching / status - light".
4.2.3. OBJECT 6 EXTERNAL MOVEMENT - HVAC
12
Input 1 Bit
Object 6 "External movement - HVAC - switch" is identical to object 2 "External movement - light - switch".
