Fan control

A6V11545892_en--_a 91 | 150
Fan control is set to enable by default (P350 = 1), if the thermostat is set with
control sequence “H/C ceiling with PICV and 6-port ball valve as changeover”. For
this application, where the combi valve PICV controls the flow rate and the 6-port
ball valve works as changeover heating / cooling, fan control can:
● Also be disabled (P350 = 0)
● Run only in heating (P350 = 2) sequence
● Run only in cooling (P350 = 3) sequence
For this application, only DC fan control is available at output Y50.
