    MB_ADDR_ZONE_TEMPERATURE_TARGET - A variable that determines a currently set target temperature. Allowable values variable fall within range from MB_ADDR_ZONE_TEMPERATURE_MIN to MB_ADDR_ZONE_TEMPERATURE_MAX. Attempt to record a number beyond the allowable values leads to an error message. The variable is stored in backed-up EEPROM memory.

    Caution !!! • Values recorded in the register are rounded to 0.5[°C].. E.g. sending a number equal to 2254 (22.54[°C]) to the register leads to setting a value of 2250 (22.50[°C]). • Should the recorded value of the minimal temperature be lower than currently set target temperature (MB_ADDR_ZONE_TEMPERATURE_TARGET), the value of target temperature will be overwritten by the maximal temperature value .

    Caution !!! • Values recorded in the register are rounded to 15[min]. E.g. sending a number equal to 905(15:05) to the register will lead to set the value equal to 900 (15:00) • The value in MB_ADDR_ZONE_SCHEDULE_MON_FRI_WORK_2_START must be lower than the value in MB ADDR ZONE SCHEDULE MON FRI WORK 2 STOP.
