AC controls

Ability to set room AC system fan speed and setpoint via Mount Kelvin API. The setpoint and fan speed are exposed via BACnet/IP. Minimum and maximum values for setpoints can be given, to limit the end user's ability to change temperature (e.g. 19–23C°)

Use case: Using hotel's own app, a room tablet, or reception software to directly control AC temperature and fan speed

The use of feature requires the customer to implement Mount Kelvin API integration in their own systems

Workflow

  1. Create the following objects for every room. nnn is the room number.

AC object names

Object nameFeatureObject type
Hnnn.SetpointNvMk

Examples

NameDescription
H513.SetpointNvMk
Setpoint for room 513
H274.RoomTemperatureNvMk
Room temperature of room 274
H429.FanspeedNvMk
Fan speed for room 429

  1. Set the object type for fan speed to a multi-state value.

    2. (Setpoint and room temperature are analog with a temperature range defined by the system)
