Máy điều nhiệt phải ở chế độ tương ứng với lệnh được gọi trước khi thay đổi điểm đặt nhiệt độ. Lệnh và(các) trường để thay đổi(các) điểm đặt sẽ khác nhau tuỳ theo chế độ của máy điều nhiệt.
Ví dụ: để đưa ra lệnh SetHeat, trước tiên, máy điều nhiệt phải ở chế độ SƯỞI ẤM:
Nhiệt độ mục tiêu tối thiểu cần đặt khi máy điều nhiệt ở chế độ HEATCOOL.
number Ví dụ: 20.0
coolCelsius
Nhiệt độ mục tiêu tối đa cần đặt khi máy điều nhiệt ở chế độ HEATCOOL.
number Ví dụ: 22.0

(Các) mã lỗi sau đây có thể được trả về liên quan đến đặc điểm này:
Thông báo Lỗi
RPC
Khắc phục sự cố
Không được phép dùng lệnh này ở chế độ hiện tại của máy điều nhiệt.
FAILED_PRECONDITION
Một số mẫu máy điều nhiệt không hỗ trợ thay đổi chế độ Tiết kiệm năng lượng khi chế độ máy điều nhiệt là TẮT, theo đặc điểm ThermostatMode . Bạn phải thay đổi chế độ của máy điều nhiệt thành HEAT, COOL hoặc HEATCOOL trước khi thay đổi chế độ Tiết kiệm năng lượng.
Giá trị làm mát phải lớn hơn giá trị sưởi ấm.
INVALID_ARGUMENT
Đảm bảo rằng trường heatCelsius nhỏ hơn trường coolCelsius trong lệnh của bạn.
Không được phép dùng lệnh khi máy điều nhiệt ở chế độ MANUAL_ECO.
FAILED_PRECONDITION
Bạn không thể đặt điểm đặt nhiệt độ khi máy điều nhiệt ở Chế độ tiết kiệm năng lượng thủ công.
