Description
M21 – intelligent pump controller
The IBO M21 controller is an electronic controller that automates the operation of a single pump and at the same time comprehensively protects it. M21 records the accumulated pump operating time and the history of the last five failures, making it easier to control the condition of the installation and diagnose possible faults more quickly. A clear display shows the status of the device in real time, and calibration for a specific pump ensures precise protection.
For whom
- Installers and plumbers - the M21 controller facilitates diagnostics thanks to failure history recording and an operating time counter, which facilitates the servicing process.
- Home owners with their own water intake - the controller automates the operation of a deep-well or surface pump and protects it against costly failures.
- Agricultural farms and allotment gardeners - the device monitors the operation of the pump when irrigating and filling tanks, reacting to the water level in the intake.
- Users who value control over the installation - viewing the operating time and recent faults allows for early detection of irregularities in the pump system.
Application
The M21 controller is suitable wherever a single single-phase pump is to operate independently and the user wants to have insight into its operation. It works with submersible pumps in home wells, with surface pumps in home water installations and with submersible pumps in reservoirs and pumping stations. It receives the on and off signal from probes, floats or a pressure switch, which allows it to be adapted to various installation configurations.
The device regulates the pump's operation depending on the water level in the tank from which it is pumping, the level in the target tank or the pressure in the system, and the record of history and operating time facilitates ongoing supervision. Thanks to this, one controller supports both simple irrigation and more demanding water supply systems.
Features of the M21 controller
The heart of the device is an electronic system with an LCD display that presents the current operating status of the pump and diagnostic messages. M21 uses double protection against dry running - it simultaneously analyzes the signal from liquid level probes or sensors and the current consumption of the operating pump. After an emergency shutdown, the controller automatically tries to restart, and the duration of this attempt depends on the type of disturbance.
Unlike the basic M121 model, the M21 controller additionally records the accumulated pump operating time and the history of the last five failures in which the protective functions were activated. This allows you to assess the condition of the installation on an ongoing basis and service it more efficiently. Work can be performed in automatic or manual mode.

Frequently asked questions (FAQ) – M21 controller
What is the M21 controller used for?
The M21 controller is an intelligent controller for automatic control of one pump and its protection. It turns the pump on and off depending on the water level or pressure, protects it against dry running and power supply irregularities, and additionally records the operating time and failure history.
What pumps can be connected to the M21 controller?
M21 works with single-phase deep-well, submersible and surface pumps with power from 0.37 to 2.2 kW with a power supply of 1 ~ 230 V. This makes it suitable for deep wells, home water installations and tanks.
What is the difference between the M21 controller and the M121 model?
M21 has the same power parameters and the same set of protections as M121, but additionally displays the accumulated pump operating time, records the history of the last five failures and uses a dynamic LCD screen. The full range of controllers can be found in the category drivers.
Does M21 protect the pump against dry running?
Yes, the controller uses double protection against dry running - it analyzes the signal from the liquid level probes and the current consumption of the operating pump. After detecting a disturbance, the pump is turned off and the controller automatically tries to restart it after a specified period of time.
Can the M21 controller be installed outside the building?
M21 has a protection class of IP22 and is intended for indoor installation. In installations with an outdoor pump, the controller itself should be placed indoors or in a suitable, protected enclosure.
Where to buy the M21 controller?
As a manufacturer, we do not sell directly. The IBO M21 controller can be purchased from our trading partners, installation wholesalers and authorized online distributors.
What is the warranty for the M21 controller?
IBO – 24 months (2 years) manufacturer's warranty.
