Description
TREVOLI General Purpose Pump Controller.
L931, L932
This pump controller can control one or two single or three phase pumps and has three different modes which can be changed easily by a switch setting. Each mode allows the controller to be used for different functions.
Mode 1: Used to supply water to a tank using float switches (not supplied) or liquid level sensors (supplied).
Mode 2: Used for pressure boosting using a pressure switch (not supplied) and pressure tank (not supplied).
Mode 3: Used to empty a tank or sump using float switches (not supplied) or liquid level sensors (supplied).
Comes with a remote monitor which allows monitoring and controlling the pump from up to 1200m distance from the controller.
