Note:
(1) The function setting of "n3" must be set to correct value according to the quantity of water module connected,
otherwise, ALARM 37 may be triggered. (For example, in case of the quantity of water module in a system is
three, then the value of "n3" should be set to " ". )
(2) The function setting of "H4" must be set to correct value according to the type of water module connected:
H4=0 (default) : water module should be used in a three pipes heat recovery system.
H4=2: water module should be used in a two pipes heat pump system.
(2)The function setting of "Ui" can be set according to application requirement:
Ui=0 (default) : performance balance between indoor unit and water module.
Ui=1: indoor unit has priority on performance.
