F3002＝8：Input 4～20mA from VRF1 terminal , 4mA corresponds to F8023 at F8022≠0 and 20mA corresponds to F8024 at
F8022≠0.
F3201 PID control action selection
● Applying with single-pump water supply function, Set F3201=1 for constant- pressure water supply control.
Note: Only may select PID1 control at single-pump water supply, the rest selections are invalid.
F3201=0：
Open loop control
F3201=1：PID1
control
F8007 Select water supply optional modes
Using single-pump mode must set F8007=15, pressure control. Please set relative codes with pressure control according to
actual demands: F8022(pressure command ),F8023(analogy feedback ：offset pressure ),F8024(analogy feedback：pressure
gain),F8025(Ratio of pressure control upper limit)、F8026(Ratio of pressure control lower limit).
F8018 Sleep wake up ratio K
●F8018 is availability with only using auxiliary pump (F8007=5～8,11～15,and F1104≠1)that it is the code which judges
whether to switch to variable frequency pump by auxiliary pump, judgment equation as follows.
K·F*≥Ff..................................... (1)
Where, F* is frequency command, Ff is frequency feedback value, k(≦1) is auxiliary pump switch ratio.
Besides, frequency command would turn into pressure command and frequency feedback value would turn into pressure
feedback value when using pressure command. The larger the k value, the more slowly variable frequency to switch. Please set it
according to pump capacity. In addition, this function code is used at main pump sleep wake up is working, method of the operation
as above.
F8019 Sleep wake up decision time T
● F8019 is availability with only using auxiliary pump (F8007=5～8,11～15,and F1104≠1), please set the decision time turn into
variable frequency pump after meeting the condition of F8018. It would be better that the set reference time is shorter without
oscillating has been generating.
● This function code is also used in the main pump sleep wake up.
F8022 Pressure command(Operation panel) Pref
● F8022 is the function code that setting the target pressure value of constant pressure water supply, it only support SC-WS water
supply board and does not support single-pump water supply function at F8022=0 .
F8023 Analog feedback: offset pressure Pb
● F8023 is a valid code when the pressure command code has been given by F8022.
F3002＝1～4: Set the pressure value corresponds to 0V
F3002＝1～4: Set the pressure value corresponds to 4mA
F8024 Analog feedback: pressure gain Pg
● F8022 is a valid code when the pressure command code has been given by F8022.
F3002＝1,4: Set the pressure value corresponds to 5V
F3002＝2,4: Set the pressure value corresponds to 10V
F3002＝9: Set the pressure value corresponds to 20mA
F8025 Pressure upper limit P
● F8025 is a valid code when the pressure command code has been given by F8022 and is upper limit ratio of pressure command.
Calculation equation: pressure upper limit = F8025(pressure upper limit ratio) * F8024（pressure gain）
● If the setting value of F8022 over F8025, it would be internally restricted by F8025, but if it is below than F8026 that would
display error.
F8026 Pressure lower limit P
● F8026 is a valid code when the pressure command code has been given by F8022 and is lower limit ratio of pressure command
Calculation equation: pressure upper limit = F8026(pressure upper limit ratio) * F8024（pressure gain）
● If the set value of F8022 is lower than F8026, it would be internally restricted by F8026, but if it is over than F8026 that would
display error.
F8027 The slope of pressure acceleration/deceleration
●
F8027 is the ratio of setting pressure variations when the pressure command code has been given by F8022. Higher set value
corresponds to faster change of pressure command.
