Room temperature setting unreasonable, indoor the case where still keeping operation of air conditioner in the case where nobody, is very common in the case where formula.
Since central air conditioner system tail-end blower fan coil pipe is substantially independent operating, so that not have trip information real-time for coiler fan
Transfer function, therefore system is caused to lack corresponding effective information, so that entire management system can only pass through simple start and stop control
Mode processed controls the operation of fan coil, not can be carried out effective intelligent management and control.
