Controlling the lighting and the ventilation in a toilet room

Use case

Your customer wants to automatically control the lighting and the ventilation in the toilet room using a mini detector.

When movement is detected:

the lighting is activated. The lighting is deactivated 1 min after the last movement detection.
the switch ventilator is activated after 5 min. The switched ventilator is deactivated 1 min after the last movement detection. In this manner, the ventilator is not activated when a person is in the toilet room for less than 5 min.

Procedure

Creating the controls and devices

Create a mini detector (DET1)
Create the following devices:
- a virtual device (VIRT1)
- a lamp (LAMP1)
- a switch ventilator (FAN1)

Creating the routine

Create a routine Motion detection with mini detector(s) (ROUT1) to activate the virtual device (VIRT1). Configure the following behaviour:

Master mini detector that initiates the routine: DET1
Device that is switched on when the routing is started: VIRT1: Value = true

Creating the condition

Create a condition (COND1) that activates LAMP1 immediately and FAN1 after 5 min, and deactivates both 1 min after the last movement detection. Use the following logic:

IF (VIRT1: Value = true)
THEN (LAMP1: Value = on, Delay = 0 s) and (FAN1: Value = on, Delay = 5 min)
ELSE (LAMP1: Value = off, Delay = 0 s) and (FAN1: Value = off, Delay = 1 min)

Filling the cabinet and addressing the devices

Fill the cabinet with ...	and address the following devices ...
a switching module (3X) 2U (MOD1)	switch ventilator FAN1. lamp LAMP1.
