8.3.4 Protocol RS-485


The interface operates with 1 stop bit, no parity bit and 8 data bits.

Transfer rate either: 2400, 4800, 9600 (Factory setting) or 19200 baud as se-
lected.

The RS-485 commands are always preceded by the device address. There is
provision for 127 addresses. The address must always have 3 digits.
(A000_...to A127_...).

The command from the computer must be terminated with CR.

The response of the thermostat is always terminated with CR.
CR = Carriage Return (Hex: 0D)
Example:
Transfer of setpoint 30.5 °C to the thermostat with address 15.
