*registers of single record (one message must include a record of only one register)
Table 14: Memory register type data block organization.
Caution !!! Recording registers with addresses from 0 to 3 must contain a record of only one
variable. For example, to set the rate of MODBUS transmission, the parity mode and device address must
send three separate messages. The attempt to record two or three registers at the same time leads to an error
message.
MB_ADDR_BAUDRATE ^ variable determining a transmission rate with which the device operates
on MODBUS bus. Allowable values for variable are 480, 960, 1920, 3840 (4800[bps],
9600[bps], 19200[bps], 38400[bps]). Attempt to record other value leads to an error message. Upon sending
correct value, other than the current one, a record will take place of new transmission rate in backed up
EEPROM memory, and triggering of device reset procedure.
Transmission rate = MB_ADDR_BAUDRATE * 10[bps].
MB_ADDR_PARITY_MODE - Parity mode for MODBUS transmission. Allowable values for
variable and a number of alloy bits (according to MODBUS specification):
Parity mode
Variable value
Number of alloy

Table 15: Parity mode
An attempt to record values beyond the table leads to an error message. Upon sending a proper value, other
than current one, new parity mode will be recorded in in backed up
9

EEPROM memory, and the device reset procedurę will be triggered
MB_ADDR_SLAVE_ADDR - address of the device on MODBUS bus. Allowed values for variable
within a range from 1 to 247. Attempt to record other number will lead to an error message. Upon sending a
correct value, other than the current one, new address will be recorded in the backed-up EEPROM memory,
and the device reset procedure will be triggered
MB_ADDR_NTC_1_CORRECT - Register allowing setting the correction value for temperatures
read from the in-built NTC10K sensor. Allowable values fro variable within a range from -800 to 800 (-8
[°C] do 8 [°C]). Attempt to record a number beyond the allowable values will lead to an error message.
Variable stored in the backed-up EEPROM memory
TCorr = (MB_ADDR_NTC_1_CORRECT / 100)[°C].
MB_ADDR_NTC_PERIOD - Variable determining a time period between subsequent temperature
measurements. Allowable values for a variable within a range from 0 to 65535, whereas zero means
switching off the temperature read. Variable stored in a backed-up EEPROM memory. Measurement period
is determined on the basis of the formula:
Tpom = (MB_ADDR_NTC_PERIOD * 0.1) [s].
MB_ADDR_RTC_WEEK_DAY - variable that determine a currently set day of the week. Particular
days correspond to following numbers:
Register value

0
Monday
1
Tuesday

Table 16: days of the week.
Caution !!! Day of a week is set automatically by the device on the basis of current date (see

day in relation to current date leads to an error message.
10

MB_ADDR_RTC_YEAR - a variable that determines a currently set year. Allowable values for the
variable fall within a range from 0 to 99. Attempt to record a number beyond allowable values leads to an
error message.

the variable fall within a range from 1 to 12. Attempt to record a number beyond allowable values leads to an
error message.
MB_ADDR_RTC_DAY - A variable that determines a currently set day of a month. Allowable
values fall within a range from 1 to 28/29/30/31 (depending on a set month or in case of simultaneous record
of MB_ADDR_RTC_MONTH,MB_ADDR_RTC_DAY of a month given in a message sent). Attempt to
record a number beyond allowable values leads to an error message.

MB_ADDR_ZONE_TEMPERATURE_TARGET - A variable that determines a currently set target
temperature. Allowable values for the variable fall within the 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.
TTARGET = (MB_ADDR_ZONE_TEMPERATURE_TARGET / 100)[°C] / [ºF].
Caution !!!
• Values recorded in the register are rounded to 0.5[°C]/[°F].. E.g. sending a number equal to 2234
(22.34[°C]) to the register leads to setting a value of 2200 (22.00[°C]), analogical for [°F].
MB_ADDR_ZONE_TEMPERATURE_DELTA - a Variable that determines a hysteresis of temperature for
two-state algorithm controlling the environment. Allowable values for the variable fall within a range:
-[°C]:
from 50 to 200 (0.50[°C] do 2.00[°C]). Attempt to record a number beyond the allowable values leads to an

-[°F]:
from 50 to 200 (0.50[°F] do 2.00[°F]). Attempt to record a number beyond the allowable values leads to an
error message. The variable is stored in backed-up EEPROM memory.
TDELTA = (MB_ADDR_ZONE_TEMPERATURE_DELTA / 100)[°C] / [ºF].
Caution !!!
• Values recorded in the register are rounded to 0.5[°C].. E.g. sending a number equal to 59 (0.59[°C]) to
the register leads to setting a value of 50 (0.50[°C]), analogical for [°F].
MB_ADDR_ZONE_TEMPERATURE_MIN - a variable that determines a minimal temperature
that will be possible to be set in MB_ADDR_ZONE_TEMPERATURE_TARGET.
. Allowable values for the variable fall within a range:
-[ºC]: From 500 to (( MB_ADDR_ZONE_TEMPERATURE_MAX - 500) (from 5.00[°C] to MAX-

9.00[°F])
Attempt to record a number beyond the allowable values leads to an error message. The variable is
stored in backed-up EEPROM memory.
TMIN = (MB_ADDR_ZONE_TEMPERATURE_MIN / 100)[°C].
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 higher than currently set target temperature
(MB_ADDR_ZONE_TEMPERATURE_TARGET), the value of target temperature will be
overwritten by the minimal temperature value .
MB_ADDR_ZONE_TEMPERATURE_MAX - A variable that determines a maximal temperature
that will be possible to be set in MB_ADDR_ZONE_TEMPERATURE_TARGET. Allowable values for the
variable fall within a range
-[°C]:

from (MB_ADDR_ZONE_TEMPERATURE_MIN + 900) to 10400 (from MIN+9.00[°F] to
104.00[°F]).
Attempt to record a number beyond the allowable values leads to an error message. The variable is stored in
backed-up EEPROM memory.

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.
MB_ADDR_ZONE_ACTUAL_PROGRAM_STATE - Register that contains information on device
operating status deriving from the schedule.
