(*) The Y3 analogue output is used to manage the modulating
fan. The output can be controlled in two modes: 0/10V or
phase cut (for MCHRTF regulators).
The working mode is set using parameter 136L (0/10V or
phase cut).
Selecting "phase cut" will make parameters 136M, 136N and
136O available. These parameters can be used to set the triac
for the control of the MCHRTF device.
