PA
00 Not Available (Default Setting)
01 Forced heating standby of indoor units when SW BOX connected in and ambient temperature
＜
76°F(24°C) .
NOTE:
(1)The function setting of “n3” must be set to correct value according to the quantity of water modules connected, otherwise, ALARM 37 may be triggered. (For
example, in case of the quantity of water modules 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.
(3)The function setting of “Ui” can be set according to application requirement: Ui=0 (default) : Capacity balance between indoor unit and water module.
Ui=1: Indoor unit will have priority on performance.
