Device status as for event (1 byte)

Byte number	Description
0	Device status. 0 bit: 0 – zone is off 1 – zone is on 4-7 bits – number of current automation mode. Number is depending on order of automation description in logic.

Device status upon status request (6 bytes)

Byte	Description
0	Device status. 0 bit: 0 – zone is off 1 – zone is on 4-7 bits – number of current automation mode. Number is depending on order of automation description in logic.
1-2	Set-point temperature, low-high bytes
3-4	Middle temperature of connected sensors, low-high bytes
5	254 – "Always off" mode 255 – "Manual" mode

Possible variants of setting the status

Byte	Description
0	0 – off 1 – on 0xFF – Change the status for the opposite one
