Room Occupancy, Open Door Courtesy Light, Toilet Occupancy, Occupancy Indication by Doorbell, Window/Aircon Linkage
Room Occupancy Sensing
This is function for energy saving based on PIR motion detection. If none of the channels are Room PIR then this function is not enabled.
If Keycard is not enabled, the occupancy status is solely determined by the PIR and Door sensor.
If the Room PIR is present, the Room Occupancy function sensing is enabled.
When the Door Sensor is closed, the Primary Relay Occupancy Timer, Secondary Relay Occupancy Timer and Lighting Occupancy Timers are started. If the delay is disabled (FF) then the corresponding timer will not start and the function does not work.
If the Room or Toilet PIR detects motion or any ELV switch is pushed, the timers are stopped and Occupancy Status is set to ON.
If the PIR does not detect motion during the Primary Relay Occupancy timer delay, the Primary Relay output is switched off, and the ELV channels/lights are switched off. Occupancy status is changed to OFF.
If the Secondary Relay Occupancy Delay expires without motion, the Seconday relay is switched off as well as all lighting channels.
If the Lighting Occupancy Delay expires without motion, all lighting channels are switched off.
If motion is subsequently detected, the Primary Relay, Secondary Relay and the channels/lights that were switched off are switched on again, and Occupancy Status is changed to ON.
Open Door Courtesy Light
This function is enabled by the presence of the Door Sensor. If the room is not occupied (Occupancy Status off), when the Door is opened the Secondary Relay output will be turned on and Courtesy Scene will be activated for the duration of the Courtesy Light Timer. If the courtesy light timer is disabled, the timer will not start and the courtesy lights do not switch off automaticaly
If the Keycard is inserted, the occupancy status is set to on.
If the Room or Toilet PIR detects motion within the Courtesy Light delay (for Keycard not enabled), occupancy status is set ON, and Primary relay turns on. The Welcome scene is activated.
If the keycard is not inserted or PIR is not active by the expiry of the timer, the Secondary relay is switched off and the courtesy lights are switched off.
Toilet Occupancy Sensing
This function requires a Toilet PIR as one of the channels. The purpose of this is convenience, so that when someone goes into the toilet, the toilet lights are automatically turned on. The Toliet light does not switch off automatically, to prevent people sitting still causing lights to turn off
If present, the Toilet PIR also determines occupancy in conjunction with the Room PIR.
Occupancy Indication by Doorbell
A method of telling the cleaning staff whether the room is occupied is by pressing and holding the Doorbell for (6) seconds. Then the MUR and DND will turrn on for 1 second. After that, the occupancy is shown on the MUR and DND leds (inside as well as Outside the room) until the doorbell is released. If unoccupied, MUR is on. If Occupied, the DND is on. Occupancy is determined either by Keycard or occupancy sensing. Doorbell pulse width is 100ms to 4 seconds in 100ms intervals, which starts when the doorbell is released if the press duration is less than (7) seconds. This function is enabled by “Occupancy Indication by Doorbell†in Properties
Window/Aircon Linkage
If the Window Timer is set to a nonzero value and one of the channels is a Window. This function is enabled. When the window is opened, the Window Timer will start. If the Window remains open at the end of the delay, the Primary Relay or Keycard Output is turned off.
