(*) For the HMG-P series
Note:
— if the temperature value is invalid or absent, the letters "N/A" are shown
— for the "Anti-freezing-T" and "Anti-over-heating-T" parameters, only the "An-
ti-freezing-T" parameter will be visualised if the set mode is "cool"; if any other
mode is set, only the "Anti-over-heating-T" parameter will be visualised
(3) Error:
Pressing the "Error" button will take you to information about errors on the unit;
Note: the system will display the active errors on the unit, oering a list if there
are more than one (if more than 5, they will be divided into pages, which can be
changed using the arrow keys on the right and left side of the window);
