Meaning of values at offsets 0x06/0x07 and 0x08/0x09.

Hi, in case of my unit I've found the following: 1400 is controller night target temperature -> 14.00 degree C and 1900 is controller day target temperature -> 19.00 degree C

• 0x00 -- unknown -- 0xa5 or 0xa7
• 0x01 -- MSB of 16 byte boiler pairing code
• 0x02 -- LSB of 16 byte boiler pairing code
• 0x03 -- command byte (0x20: on, 0x00: off, 0x04: pairing)
• 0x04/0x05 -- 16 bit fixed point controller temperature (divide value by 100).
• 0x06/0x07 -- unknown (suspiciously has a value of 1400, which looks like a time for boiler scheduling, but doesn't reflect my configuration)
• 0x08/0x09 -- unknown (sometimes has a value of 1900, which again looks suspicious)
• 0x0a -- unknown (usually has a value of 50)
• 0x0b -- checksum (simple sum of all other bytes mod 256)

Best!,
Mike
