Abstract
For monitoring an HVAC system (1), HVAC data reporting messages are received and stored in a cloud-based computer system (4). Each HVAC data reporting message includes one or more operation data values included by an HVAC controller (22) of the HVAC system (1). The cloud-based computer system (4) generates (S73) remote diagnoses for a particular HVAC device, using a plurality of HVAC reporting messages received from a plurality of the HVAC controllers (22) from one or more HVAC systems (1). Each remote diagnosis is generated (S73) by using more than one operational data value, included in HVAC reporting messages received (S71) received from HVAC controllers (22) of more than one HVAC systems (1) and/or from at least two different types of operational data values. A diagnosis message which includes a remote diagnosis is transmitted to a diagnosis processing system for the particular HVAC device.
