Setting about S1 & S2 switch
S2 Switch----Long distance demand
6.1 Second Set Point available when S1 switch has well connected.
At the same time, water temp set point setting decided by ambient temp, Parameter
SET 9 and Parameter SET A. (Both SET 9 & SET A Parameter would be adjusted)
o
Parameter SET 9 (maximum setting range 45~60 C)
o
Parameter SET A (minimum setting range 20~40 C)
o
A. When ambient temp < 5 C, set point temp refer to the data of Parameter SET 9
o
B. When ambient temp >15 C, set point temp refer to the data of Parameter SET A
o
o
C. When 5 C
≤
ambient temp
≤
15 C, Set point temp = Data of Parameter SET 9-
(Data of parameter SET 9- data of parameter of SET A)/(15-5)*(Ambient temp -5 )
For example, when ambient temp is 18 deg c, Parameter SET 9 data is 50 deg c,
Parameter SET A data is 20 deg c.Then set point temp =50-(50-20)/(15-5)*(18-5)
S1 Switch---Second Set Point
6.2 When S1 disconnected, set point temp control by LCD controller. (Refer to the
setting of Parameter 40 (default setting 50 deg c).
6.3 Heat pump will turn on when S2 switch has well connected.However, S2 well
connected, and suddenly press the off button on the LCD controller.Heat pump
will stop for 3 minutes. After 3 minutes heat pump continue to turn on if S2 Still
has been connected.
6.4 The timer function is out of validity when S2 switch is connected.
6.5 Heat pump turns off when S2 switch is disconnected. Meanwhile, need to use
LCD controller to switch on/off the heat pump.
