<P>PROBLEM TO BE SOLVED: To provide a controller for a heat pump type hot-water supply device capable of preventing breakdown of an element constituting a converter and an inverter due to excess voltage without arranging another discharging means by arranging a control means for controlling to operate an electric driving means attached to a heating device. <P>SOLUTION: An electric motor 6 for a pump for pumping fluid for hot-water supply into a heat pump unit 2 in which electric power is supplied by the converter 31 and which is driven based on operation command of the controller 3 is provided. The controller 3 controls to detect voltage in an output part of the converter 31 by power generation action of an electric motor 5 for a blower by its number of revolutions when the electric motor 5 for the blower rotates by external force and drive the electric motor 6 for the pump when the voltage rises above a predetermined value. Consequently, it is possible to prevent breakdown of the element constituting the converter and the inverter due to excess voltage without arranging another discharging means. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
