Abstract

PURPOSE: To improve operating property by a system wherein a low-head large- discharge pump and a high-head small-discharge pump are connected in parallel to a hot-water supply circuit, and a heat source is controlled automatically for operation with a pressure switch provided on discharge side of the pumps.
CONSTITUTION: Since pressure does not work on a system entirely at first, a pressure switch 7 is turned on from turning a power switch 8 to ON position, and a relay SP for operation of a signal pump 4 is actuated. When a pressure working on the pressure switch 7 reaches a set point or over by operation of the signal pump 4, the pump 4 is turned off. From opening a valve 9 for a fan convector 6, a passage for hot water opens to drop the pressure, a contact Pb of the pressure switch 7 is turned on to actuate the pump 4. After passing given period of time under this state, a delay timer TR is turned on, a relay MP for operation of a main pump 3 and a relay B for operation of a heat source are turned on, thus commencing heating.
