However, since the burner combustion amount is constant regardless of the number of radiators operating,
Not only does the hot air temperature change according to the number of radiators operating, but when the number of operating radiators is low, the heat medium temperature of the heat exchanger rises excessively and burner combustion-stopping is frequently repeated, However, there was a problem in that the room temperature does not reach the desired temperature when there are many.

Then, the high voltage of the connection point (64) is input to the operational amplifier (65), the output voltage of the operational amplifier (65) is increased and the conductivity of the transistor (66) is increased, so that the energizing current of the proportional valve (14) is increased. Becomes
The valve opening also becomes large. Therefore, the burner (2) starts combustion with strong combustion. After that, when the predetermined time has passed and the capacitor (71) is sufficiently charged, the inverter (72)
Input becomes “H” and its output becomes “L”. At this time, the "L" output of the inverter (49) is input to the inverter (59), the output of the inverter (59) becomes "H", the transistor (60) is turned on, and the connection point ( 64) The voltage is low. Therefore, the conductivity of the transistor (66) becomes small, the valve opening of the proportional valve (14) becomes small, and weak combustion is performed in the burner (2). Further, a current flows through the capacitor (71) through the diode (74) and the resistor (70), and the charging of the capacitor (71) is completed promptly.

In this way, when the circulation pump (9) is operated based on the operation signal of the indoor control device (29A) and combustion is performed in the burner (2), the heat medium heated in the heat exchanger (3) Enters the branch passage (C1) through the heat medium tank (5), the circulation pump (9), the forward side header (20), the heat medium supply valve (10) and the pipe connection port (21), and the radiator (26A ).
Then, here, heat is exchanged with the indoor air sent by the blower fan (27A), and after being used for heating the room, heat is exchanged through the pipe connection port (17) and the return side header (19). Return to the vessel (3) and repeat the circulation indicated by the experimental arrow. At the beginning of heating, the burner (2) burns strongly regardless of the number of relay switches turned on, so that not only is ignition satisfactorily performed, but also the temperature of the heat transfer medium is rapidly raised, and the radiator (26
Room temperature in the room where A) is installed rises quickly. Further, only the heat medium supply valve (10) is opened corresponding to the relay switch (351A), and wasteful heat dissipation in the radiator (26B) is prevented. In addition, after a lapse of a predetermined time from the start of heating operation, weak combustion is performed in the burner (2), and the combustion amount becomes commensurate with the heating load, so the warm air temperature of the radiator (26A) rises extremely. As the temperature of the heat medium rises, the temperature control device for the heat medium operates, and the burner does not repeat frequent start and stop.

Only the operation switch (30B) of the indoor control device (29B) is turned on, and the thermoswitch (32B) is turned on.
The same applies when an operation signal is issued from the indoor side control device (29B) to the heat source side control device, and in this case, the heat medium supply valve (11) is opened. Then, the heat medium of the heat exchanger (3) circulates to the radiator (26B) as indicated by a dashed arrow and is used for heating the room in which the radiator (26B) is installed. Further, the burner (2) performs strong combustion for a predetermined time and then weak combustion.

Indoor side control device (29A) (29B) operation switch (30A)
(30B) is turned on and the thermo switch (32B)
When A) (32B) is on, relay switch (351A) (35
1B) turns on. In this case, the relays (55) (57) are energized in the heat source side control device (16), and the heat medium supply valve (10)
(11) opens. For this reason, the heat medium of the heat exchanger (3) is the heat radiator (26A) (26A) as indicated by solid and broken arrows.
It circulates to B) and is used for heating the room where radiators (26A) (26B) are installed. Further, since both inputs of the NAND circuit (48) become "H" and their outputs become "L", the input of the inverter (59) becomes "H" regardless of the output of the timer means (T). Then, the transistor (60) is turned off. Then, the input of the operational amplifier (65) is increased, and the proportional valve (14)
And the burner (2) performs strong combustion. In this way, when the operation signals are sent from the indoor side control devices (29A) (29B) to the heat source side control device (16) at the same time,
Since the combustion amount of the burner (2) becomes large, it is possible to prevent the temperature of the hot air in each of the radiators (26A) and (26B) from decreasing, and it is possible to quickly raise the room temperature to the set temperature.
