Abstract
An air conditioning system provided with a variable capability blower and heat source unit is configured such that individual room dampers 9 and controllers 14 can be subsequently added to a central control device as options to convert from an all room simultaneous air conditioning mode to a variable air volume mode with separate temperature control for each room. The utilization of existing power lines to transmit the various information and control signals simplifies the conversion and reduces its cost.
