DESCRIPTION OF ADVANCED PARAMETERS

The advanced parameters cannot be accessed by the final user as they are all inside a hidden menu.
These parameters can be changed to optimise operation of the inverter, to solve problems related to special installations, , to carry out
pressure and flow sensor calibration or to check the operating log.
To access the advanced parameters menu, simply press and hold the central key for approximately 5 seconds while on the temperature
display page. The system requires entry of a value from 0.0 to 5.9 in order to directly view one of the parameters of the menu.
Parameters from 0.0 to 1.1 correspond to the basic parameters accessible by the installer, while parameters from 1.2 to 5.9 are advanced
parameters as indicated in the table below.
