The operating mode switches between different operating states of the room:
•
Comfort: Room occupied. The setpoint temperature is set to a default value perceived as pleasant by most users.
•
Standby: Room is briefly/recently vacant. The setpoint temperature is decreased (heating) or increased (cooling)
•
Economy: The room is unused for an extended period (e.g. overnight), and the temperature is markedly decreased
(heating) or increased (cooling).
•
Frost/heat protection: The room or building is unused for an extended period (e.g. school during vacation). The setpoint
temperatures are adjusted to the minimum (heating – frost protection) or maximum (cooling – heat protection) values that
are still acceptable without damaging the installation.
