EZ Boost Controller
The EZ Boost controller is a control and communication
unit especially developed for the BMQE booster pumps in
constant pressure applications.
The EZ Boost controller provides:
• Full control of the BMQE pumps
• Two-way communication with the BMQE pumps
• Possibility of adjusting the pressure
• Alarm indication (LED) when service is needed
• The possibility of starting, stopping and resetting the
pump simply by means of a push-button
The EZ Boost controller communicates with the pump via
power line communication, meaning that no extra cables
are required between the EZ Boost controller and the BMQE
pump.
The EZ Boost controller features the following indications
(see drawing below):
1. Flow indicator
2. System pressure setting
3. System ON/OFF
4. Button lock indicator
5. Dry-running indicator
6. Service needed in case of:
– No contact to pump

The EZ Boost controller incorporates external signal input
for pressure sensor.
