Reading parameters
For the OPTION parameters, refer to the instructions for the "Dual zone management" option for more information. N13.61
To access rapid reading of the values measured by the heat pump sensors and probes, we recommend that you refer directly to
the measurement table accessible in the Information menu .
All of the values measured and calculated by the control are available in the Reading parameters sub-menu. Parameters
indicated by the
symbol can be accessed by the user.
