When automatic switching between cooling and heating is set by default, the MPU 35 controls the valves 51 and 52 via the valve I / F 40 according to the difference between the room temperature and the set temperature. Cooling and heating are performed according to the difference between the room temperature and the set temperature. When the room temperature is equal to or higher than the set temperature + cooling hysteresis value, the MPU 35 performs cooling by controlling the valves 51 and 52 via the valve I / F 40 according to the difference between the room temperature and the set temperature. When the temperature is equal to or lower than the cooling-hysteresis value, heating is performed by controlling the valves 51 and 52 via the valve I / F 40 according to the difference between the room temperature and the set temperature. I do.

The MPU 35 turns on / off the valve by default.
When the off control is set, as shown in FIG.
During normal operation, when the valves 51 and 52 are closed and the room temperature reaches a range set by the set hysteresis value with respect to the set temperature, the valves 51 and 52 are connected via the valve I / F 40.
When the room temperature reaches the set temperature while the valves 51 and 52 are open, the valve 5 is opened via the valve I / F 40.
1, 52 are closed.

When the floating control (proportional control) of the valve is set in the initial setting, the MPU 35 controls the opening degree of the valve in the cooling mode and the heating mode as in the case of the two-pipe one-coil system. Is performed, and the opening degrees of the valves 51 and 52 are controlled via the valve I / F 40 based on the relationship between the set temperature and the current room temperature.

The transfer of data between the MPU 35 and the communication interface unit 44 is realized by a configuration in which the MPU 35 is a master, the communication interface unit 44 is a slave, and the MPU 35 has the initiative of data transmission and reception. Data transfer between the MPU 35 and the communication interface unit 44 is executed with a transmission / reception ticket called a token. In order to perform transmission, a token must be possessed. The token is generated by the MPU 35 which is a master of data transmission and reception at the time of communication initialization.
Is owned by Therefore, the communication interface unit 44 which is a slave for data transmission and reception is connected to the MPU 3
Only when a token is passed from 5 can transmission be performed.

That is, the MPU 35 continues the current operation state by the a-contact input signal or the b-contact input signal when the initial setting is made such that the operation by the a contact input signal or the b contact input signal is continued. When an initial setting is made to stop the operation by the a contact input signal or the b contact input signal, the operation is stopped by the a contact input signal or the b contact input signal. The MPU 35 starts the operation in the in-room operation mode by the a-contact input signal or the b-contact input signal when the operation based on the a-contact input signal or the b-contact input signal is initialized in the in-room operation mode. And
