Control units (Celsius/Fahrenheit/Scale)

LED display temperature units

This command set is used to change the LED display temperature units. Celsius and Fahrenheit degrees are available.

SET

Byte index	Hex value - Meaning
0	55 – The command code.
1	00 – Set the LED display temperature to be in Celsius degrees. 01 – Set the LED display temperature to be in Fahrenheit degrees. 02 - (Available only for FW ≥4.6) Set the display to behave like a conventional thermostat with scale 0-5. There are dedicated commands to assign temperature to scale levels at the link (command code 0x69).

Example command: 0x5501 – Set the LED display temperature to be in Fahrenheit degrees

The default configuration per region is in the table below:

Celsius	✔		✔	✔

Scale 0-5 (conventional thermostat)

Vicki can operate in a mode where the display operates as one on a traditional thermostat, displaying levels instead of the target/setpoint temperature.

This command allows to set individual target temperature to the corresponding scale level. In the table below the default values are shown.

The allowed levels are in the range 0 to 5.

The command accepts only ascending values.

Scale level	Corresponding default target temperature
0	7.0°C
1	12.0°C
2	16.0°C
3	20.0°C
4	23.0°C
5	26.0°C

The desired target temperature for each scale level is pre-multiplied by 10 in order to be configurable by steps of 0.1°C, thus 2 bytes are being used for each scale level (Max. acceptable value here is 30°C, which results in a payload of 300 = 0x012C. Min. acceptable value is 5°C, which results in payload of 50 = 0x0032).

SET

Byte index	Hex value / Meaning
0	69 – command code
1	Scale level 0 target temperature – MSB.
2	Scale level 0 target temperature – LSB.
3	Scale level 1 target temperature – MSB.
4	Scale level 1 target temperature – LSB.
…	…
11	Scale level 5 target temperature – MSB.
12	Scale level 5 target temperature – LSB.

Example: 0x69004600BD00CA00E100FA012C

Set 7.0°C for scale level 0 (0x0046 = 70).

Set 18.9°C for scale level 1 (0x00BD = 189).

Set 20.2°C for scale level 2 (0x00CA = 202).

Set 22.5°C for scale level 3 (0x00E1 = 225).

Set 25.0°C for scale level 4 (0x00FA = 250).

Set 30.0°C for scale level 5 (0x012C = 300).
