    摘要: Disclosed is a control method of an air conditioner system, the method including: transmitting, by a first unit among a plurality of units belonging to a particular group, a wireless signal auto tuning command to a second unit; measuring, by the second unit, reception sensitivity and a transmission and reception success rate, by wirelessly communicating with units belonging to the particular group while reducing signal strength from default signal strength; when the reception sensitivity and the transmission and reception success rate, which are measured by the second unit, satisfy the predetermined standard, determining, by the second unit, that signal strength corresponding to a level right before a level satisfying a predetermined standard is signal strength for use; and transmitting, by the second unit, information related to the signal strength for use to the first unit. Accordingly, it is possible to set optimal signal strength at which mutual interference is prevented.

    摘要: A method of monitoring a HVAC system to detect erroneous sensor installation. The method includes determining whether a circulation fan has been operational for a first predetermined time interval. If the circulation fan has been operational for the first predetermined time interval, determining whether a cooling demand is present. If the cooling demand is present, determining whether the HVAC system has been conditioning air for the first predetermined time interval responsive to the cooling demand. If the HVAC system has been conditioning the air for the first predetermined time interval, determining whether a difference between an indoor air temperature value corresponding to an enclosed space and an air temperature value from a discharge air temperature (DAT) sensor is greater than a predetermined temperature value. If the difference is not greater than the predetermined temperature value, forwarding a message indicating that the DAT sensor positioned within a duct of the HVAC system is improperly installed.
