Setting about S1 & S2 switch
S1 Switch---Second Set Point
S2 Switch----Long distance demand
8.1 Second Set Point available when S1 switch has well connected.
At the same time, water temp set point setting decided by ambient temp, Parameter 9 and
Parameter 10. (Both 9 & 10 Parameter would be adjusted)
Parameter 9 (maximum setting range 65~80
°
C)
Parameter 10 (minimum setting range 40~55
°
C)
A. When ambient temp < 5
°
C, set point temp refer to the data of Parameter 9
B. When ambient temp >15
°
C, set point temp refer to the data of Parameter 10
C. When 5
°
C
≤
ambient temp
≤
15
°
C, Set point temp = Data of Parameter 9- (Data of
parameter 9- data of parameter of 10)/(15-5)*(Ambient temp -5 )
For example, when ambient temp is 18 deg c, Parameter 9 data is 60 deg c, Parameter 10
data is 20 deg c.Then set point temp =60-(60-20)/(15-5)*(18-5)
3.8.2 When S1 disconnected, set point temp control by LCD controller. (Refer to the setting of
Parameter 40 (default setting 50 deg c).
3.8.3 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.
3.8.4 The timer function is out of validity when S2 switch is connected.
3.8.5 Heat pump turns off when S2 switch is disconnected. Meanwhile, need to use LCD controller
to switch on/off the heat pump.
