Table 22: input register type data block organization
MB_ADDR_ZONE_TEMPERATURE_ACTUAL - register that contains information on current
temperature of a room in which the device is located. As a result of the register read, the vaue is obtained,
from which the temperature is determined through the following formula:
T measured = ( MB_ADDR_ZONE_TEMPERATURE_ACTUAL / 100)[°C]
Caution !! In case of damage to the sensor, the value obtained due to read, will equal to -32768,
which gives a temperature of 327.68[°C]. Moreover, in MB_ADDR_NTC_1_ACTIVE (see subsection. 2.3)
am activity marker for this sensor will disappear.
