Functions and Control 7.Funcitions and Control 7.1 Main functions and control specification 7.1.1 Automatic operation When the running mode is turned to automation after starting the system, the system will first determine the running mode according to the current room temperature and then will run according to the determined mode.
Functions and Control Control feature: send the dehumidifying signal to the outdoor system. When Tr>Ts+2℃, the compressor will be turned on, the indoor fan will operate at the set speed. When Tr is between the Ts and Ts+2℃, the outdoor system will operate at the high dehumidifying frequency for 10 minutes and then at the low dehumidifying mode for six minutes.

Functions and Control 7.1.4 Heating operation mode. * temperature control range: 16---30℃ * temperature difference: ±1℃ * control feature: the temperature compensation is automatically added and the system will send the heating signals to the outdoor system. If Tr+0.5℃≤Ts, the outdoor compressor is turned on, the indoor fan will be at the cold air proof mode. If Tr>Ts+1.5℃, the outdoor system is turned off, the indoor fan will be at the heat residue sending mode.

Functions and Control Send strength operation signal to the outdoor system. The mode change finishes the strength operation. Entering ‘mute’, you can have normal operation or signal control such as timing to finish the strength operation. When the system is at the automatic option with the strength/ mute function, if the system enters the cooling mode, the cooling strength/ mute function will be offered;...
