Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for controlling the operation of a heat source unit in a hot water heating system. In particular, the present invention relates to a processing method when the operation of the heat source device is stopped by the operation stop signal from the hot water heating terminal.

[0002]

2. Description of the Related Art A plurality of hot water heating terminals installed in a room are connected in parallel to a heat source device, and hot water heated by the heat source device is circulated between the plurality of hot water heating terminals and the heat source device. ,
A heating system that heats a room by radiating heat with each hot water heating terminal is used.

In such a heating system, the heat source unit can start or stop the combustion operation by a switch operation by a remote controller. On the other hand, with the operation panel provided in each hot water heating terminal,
The operation of starting or stopping the operation of each hot water heating terminal can be operated.When the heating operation of each hot water heating terminal is started or the heating operation is stopped, the operation start signal or the operation stop signal of the terminal is operated. Is sent to the heat source unit.

[0004]

However, in such a hot water heating system, when a heat source unit is burning and performing a heating operation, a certain hot water heating terminal stops heating operation and operates the heat source unit. When the stop signal is sent, the heat source unit stops the combustion operation even though other hot water heating terminals are operating. And when the operation switch of the remote controller of the heat source unit is turned on,
Since the remote controller transmits an ON signal to the heat source unit at a constant cycle, even if the heat source unit stops burning due to the operation stop signal from the hot water heating terminal, the heat source unit is immediately returned to the combustion state.

For this reason, the heat source unit performs hunting by performing unnecessary operations of stopping and restarting combustion, thereby causing a problem that the life of the device is shortened and incomplete combustion may occur.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned technical problems, and an object of the present invention is to provide a hot water heating system that performs a hunting operation of a heat source unit when the operation of a hot water heating terminal is stopped.

[0007]

According to a first aspect of the present invention, there is provided a method for controlling operation of a heat source device in a hot water heating system, comprising: a heat source device for supplying hot water; and a plurality of hot water heating terminals connected to the heat source device. In a hot water heating system including a remote controller for controlling the heat source device, when the heat source device performs a combustion operation and receives an operation stop signal from any of the hot water heating terminals, the heat source device Is characterized in that the combustion operation is stopped after the combustion operation is continued for a predetermined time.

[0008]

According to the operation control method of the heat source device in the hot water heating system according to the first aspect, the heat source device does not immediately stop the combustion operation even if it receives the operation stop signal from the hot water heating terminal, After continuing the combustion operation for a time, the combustion operation is stopped with a delay. Therefore, even if one hot water heating terminal stops heating operation and outputs an operation stop signal to the heat source device, if the other hot water heating terminal is performing heating operation, the heat source device is delayed and stops the combustion operation. Before the operation, the ON signal is output from the remote controller to the heat source device, so that the heat source device continues the combustion operation without stopping the combustion.

Further, when one hot water heating terminal stops heating operation and outputs an operation stop signal to the heat source unit, and when the other hot water heating terminal is stopped operation, the remote controller sends an ON signal to the heat source unit. Is not output, and the heat source device stops the combustion operation with a delay.

Therefore, the heat source device stops the combustion smoothly without hunting or continues the combustion state.
