4.3 Notes on settings via serial connection
All the MasterAria parameters can be viewed and those without write
protection modifi ed via serial connection (PlantVisor and Modbus®).
Below is a short description of the most signifi cant variables (for the
settings, see the summary table of parameters).
Variable Meaning Type SV ind Modbus® ind R/W
Control probe This variable contains the value of the probe used to control the MasterAria (B1 or BT).
The value considers any off sets, hysteresis, control algorithms etc. A 74 74 R
Set point setting This variable is used to read and where necessary overwrite the value of the set point
confi gured on the panel. This is especially useful if the MasterAria has the comfort
function active (e.g. centralised systems such as hotels, offi
ces etc.).
I 83 211 R/W
Control set point This variable is used to read the value of the control set point used by MasterAria.
The value considers the hysteresis, compensation factors, off sets (e.g.: sleep function),
algorithms etc. A 76 76 R
Digital inputs & heat/cool
request Heating/cooling signal: the bits are set when the unit is ON and the set point has not
been reached. Especially useful for energy saving functions. I 81 209 R
Lock keypad from panel This variable is used to disable the buttons on the terminal so as to prevent accidental
settings. Useful for centralised systems (hotels, offi
ces etc.).
I 78 206 R/W do not
modify
