Water heater
3.8.2 When S1 disconnected, set point temp control by LCD controller. (Refer to the setting of
Parameter 20 (default setting 40 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.
