PROBLEM TO BE SOLVED: To obtain a supervisory control system for air conditioning, in which a user can deliver an appropriate control command without causing confusions by displaying the record of commands to an objective air conditioner before the user delivers a control command. SOLUTION: When an operation for selecting an air conditioner 4 is carried out at a distributed control terminal 3, the record of commands to an objective air conditioner is read out from the memory section 20 of a central building air-conditioning supervisory controller 1 and displayed. A user makes a decision as to whether the command is appropriate, based on the display. When the indoor temperature is altered, for example, a decision is made whether an operation for raising the set temperature is carried out immediately before. If it is carried out, the control command is preserved, otherwise the control command is delivered. The supervisory controller 1 decides whether the control command is delivered, and if it is delivered the record of command is added and an up-to-data record of command is displayed on the distributed control terminal 3. Since a decision is made as to whether the control command being delivered by a user is appropriate, errors in control command can be avoided. |
