Esse traço pertence a tipos de dispositivos TERMOSTATO que podem informar detalhes de HVAC.
Campos
Campo
Descrição
Tipo de dados
status
Status atual do AVAC do termostato.
string Valores: "OFF", "HEATING", "COOLING"
Tempo dos eventos
Um evento de mudança no status do HVAC pode não ser entregue ao mesmo tempo que eventos de mudança no modo do termostato.
Por exemplo, às vezes há um atraso no início do modo de aquecimento ou resfriamento de um termostato para proteger o sistema de AVAC. Nesse cenário, a mudança no modo do termostato pode enviar inicialmente apenas eventos para
ThermostatMode e
ThermostatTemperatureSetpoint , com a mudança de
ThermostatHvac enviada posteriormente como um evento
separado quando o sistema for ligado. Se não houver atraso na ativação do sistema de HVAC, os três eventos serão enviados ao mesmo tempo.
