Energy Saving Lighting Control Through The LT3000/LT3384

The LT3000/LT3384 can be connected to classic switches for the multiple access and can also be used for delayed auto off, group control, and pattern control; and they can also be used for schedule control and sensor control.

  1. Multiple access for hallways and warehouses
    Multiple classic push button switches are installed along the length of the hallway to allow for multiple access.
    This is applicable not just for hallways but can be used for stairwells. Nowadays, the stairs are used less often as people tend to prefer the elevators, as such stairwell lights should only be turned on when people are using them.
    All the lights in the stairwell would be divided into circuits consisting of 5 floors each. Each of these five floors would have push button switches installed along their entrances which are connected in parallel. The switches are connected to the LT3000 input terminal, which allows the switches to control the lights indirectly through the LT3000. This will allow the group of lights to be controlled from any of these switches. In addition, the building manager can also monitor and control the same lighting circuit remotely through the IS45 or from a touch panel.
  2. Daylit hallways and restrooms
    During the day, it is desirable that the lights are restricted from being turned on, and only at night would they be allowed to be free to use. How can this be achieved?
    In order to achieve this, the LT3384 is used at the local site, the LT3384 has a special feature that allows its channels to be either forced on/off or authorized.
    When the lights are forcibly being turned either on or off, then the local switches are disallowed from being used, but
  3. Split type airconditioning
    There are many classrooms and offices that make use of split type air conditioning and the building administrator would desire that there would be some way to save energy from them as well. If the LT3000 is used, then one can choose to have a manual switch included or not, either way will work.

    1. Method 1: Equal Access
      There would be an LT3000 installed locally with a local manual switch, the building manager would have a touch panel.
      The air conditioning can be controlled locally as desired by the user. The building manager could turn off all the air conditioning after classes or work. If some is working overtime, they can still turn the air conditioning back on as needed. This is a kind of soft central control whereby local control is given as much leeway as possible, but still allow for energy saving to be achieved.
    2. Method 2: Central Only
      Locally the LT3604 would be used, but there would be no local switches, control would be exclusive to central control.
      This way, the air conditioning can only be turned on from the control center.
    3. Method 3: Authorization
      Just like in method 1, central control turns off all the air conditioning after classes and work hours. Then it can be decided whether or not to allow local control. If allowed, then the local user can turn the air conditioning on if they wanted to.
  4. Routines
    Pattern switches would be installed near the entrance, every section would have LT modules installed.

    1. The pattern control capability of the LT3000 could be used to match the routine; a button press could instruct all the lights in the area to turn on during office; another button press after office would then turn off a portion of the lights, while the last person to leave would press the “all off” button to turn off all the lights.
    2. Small private offices, showrooms, storerooms, meeting rooms and other small rooms, are places that are not always in use. Each of these rooms would have a set of switches connected to the LT3000 which would allow the user to control the lights as desired. When the user leaves, a single button press at the entrance would then turn off all the lights in the room.
