Temperature) it is set as 18 degree, but the highest heating temperature in administrative provisions winter is no more than 20 degree and provides to forbid to set heating temperature
Fixed to more than 22 degree, the first preset value is 2 degree of the highest heating temperature difference value (absolute value) of normal temperature and administrative provisions, the
Two preset values are 4 degree of the heating temperature difference value (absolute value) that normal temperature forbids setting with management.If air-conditioning 10 has been opened
Open, and the difference of the heating temperature that user is set by remote signal and normal temperature is more than 2 degree less than 4 degree, then centralized Control
Device 20 sends a control signal by signal projector 35 to air-conditioning 10, and the temperature of air-conditioning 10 is adjusted into 18 degree of normal temperature.
If air-conditioning 10 has been switched on, and user is more than 4 degree by the difference of the heating temperature that remote signal is set and normal temperature, says
The temperature value of bright remote control setting forbids the temperature value of setting higher than management, and now Centralized Controller 20 is right by output relay 38

Temperature around continuous measurement air-conditioning 10.
The difference of temperature and normal temperature around air-conditioning 10 is more than the first preset value and air-conditioning 10 has been switched on, then collects
Middle controller 20 sends control signal by signal projector 35 to air-conditioning 10, and air-conditioning 10 is adjusted into normal temperature.
For example, between summer human body feels that pleasant temperature is 24 degree to 28 degree, the standard temperature of summer
It is 26 degree to spend (optimal temperature), but the lowest refrigerating temperature of administrative provisions summer is preferably not below 24 degree, and the first preset value is
2 degree of the difference of the lowest refrigerating temperature of normal temperature and administrative provisions.If air-conditioning 10 has been switched on, and passes through temperature measurement unit
The difference (absolute value) of 32 temperature measured and normal temperature is more than 2 degree, for example the temperature that temperature measurement unit 32 measures is 23
Degree or 29 degree, then Centralized Controller 20 control signal is sent to air-conditioning 10 by signal projector 35, to the temperature of air-conditioning 10
