OPERATION

4.3.1

EXDC160 Controller

The EXDC160 controller monitors the temperature of the EXT70/70/200H Split Flow pump and the electrical power 
consumption of the pump. If the EXDC160 controller detects excessive power consumption or temperature, the 
rotational speed of the pump motor is reduced until the power and temperature return to normal.
