In case you've decided to fit an occupancy sensor, below you can find additional commands to adjust the set-point (in case of heating or cooling) and the fan speed when the room is unoccupied.

Cooling set-point unoccupied

You can change the cooling set-point with the following command set.

SET

You can set the cooling set-point with the command:

Byte index	Hex value – Meaning
0	56 – The command code.
1	XX – Cooling set-point value. Default value: 0x19 (25°C)

Example downlink: 0x5617 – Sets the cooling set-point to 0x17 - 23°C.

GET

This command gets the cooling setpoint. The keepalive data in the example below is omitted for clarity.

Byte index	Sent request	Received response
0	57 – Command code	57 – Command code.
1		XX - Cooling setpoint value.

Example downlink sent by the server: 0x57;

Example command: 0x5717 – The cooling setpoint is 0x17 - 23°C

The allowed cooling set-point range is 5...30°C (1°C resolution) by default.

Heating set-point unoccupied

You can change the heating set-point with the following command set.

SET

You can set the heating set-point with the command:

Byte index	Hex value – Meaning
0	58 – The command code.
