1. A double-deck elevator, comprising:
an upper cage and a lower cage for accommodating passengers, the upper cage and the lower cage each comprising at least one moveable door and being vertically movable together in a hoistway in a building, the hoistway having a plurality of inner walls;
covers for covering a space between the upper cage and the lower cage at a doorside, two lateral sides and a backside of the space;
a door driving unit provided in the space for opening and closing the at least one door of the lower cage; and
at least one movable door link for connecting the door of the lower cage to the door-driving unit, the door link extending in a vertical direction;
wherein at least one of the covers which covers the space at the doorside of the space covers the door driving unit and a top portion of the door link and has a first portion extending downwardly from the upper cage and positioned closer to a doorside inner wall of the hoistway than the door driving unit, and a second portion extending in a horizontal direction from the lowest portion of the first portion away from the doorside inner wall to the door driving unit, the at least one cover including at least one slit through which the door link is inserted, the slit being oriented so as to allow a displacement of said door link in a direction parallel to the direction of movement of the at least one door.
2. A double-deck elevator according to claim 1, further comprising a closing member for closing a clearance between a periphery of the slit and the door link.
3. A double-deck elevator according to claim 2, wherein the closing member is made of an elastic material and allows a displacement of said door link by an elastic deformation thereof of the bellows.
4. A double-deck elevator according to claim 2, wherein the closing member is formed as bellows and allows a displacement of said door link by an elastic expansion and contraction of the bellows.
5. A double-deck elevator according to claim 2, wherein the closing member comprises at least one brush having a plurality of bristles, the closing member permitting a displacement of the door link by an elastic deflection of the bristles.
6. A double-deck elevator according to claim 2, wherein said closing member comprises an elastic film having a slit extending in a moving direction of the door link so as to allow a displacement of said door link by an elastic deformation of the film.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of performing an HVAC system set up, the method comprising:
coupling a supervisory controller to a plurality of equipment controllers, the equipment controllers communicating with the supervisory controller over a bus;
the supervisory controller polling addresses associated with the bus to detect the presence of equipment controllers on the bus;
associating an HVAC device with each controller in response to an HVAC device designated through a user interface and assigning an address to the HVAC device; and
the supervisory controller retrieving control data from a database and loading the control data into the equipment controllers;
the supervisory controller loading operating parameters into the equipment controllers.
2. The method of claim 1 wherein the operating parameters are default operating parameters retrieved from the database.
3. The method of claim 1 wherein the operating parameters are user-defined operating parameters obtained through the user interface.
4. The method of claim 1 wherein the user interface is a graphical interface presenting graphical representations of HVAC devices.
5. The method of claim 4 wherein the graphical interface includes an air path screen for accepting input from the user for defining an air path.
6. The method of claim 5 wherein the graphical interface includes a heatingcooling screen for accepting input from the user for defining a heatingcooling device.
7. The method of claim 1 wherein the supervisory controller communicates with external sources via a communications network.
8. The method of claim 7 wherein the communications network is a TCPIP network.
9. The method of claim 7 wherein the communications network is accessed though a dial-up modem in the supervisory controller.
