A thermostat for a HVAC comprising:
a data communication port for connection to the HVAC,
wherein the thermostat is arranged to
communicate via the data communication port an operating parameter of the HVAC, andestimate an energy consumption of the HVAC from the communicated operating parameter of the HVAC.;The operating parameter may express a fraction of a nominal load of the HVAC, the thermostat being arranged to estimate the energy consumption from a multiplication of the operating parameter and a nominal energy consumption parameter of the HVAC at the nominal load. |
