Description
M121 – electronic pump controller
The IBO M121 controller is an electronic device that takes full control of a single pump’s operation while protecting it against the most common causes of failure. It combines automatic device activation and deactivation with an extensive range of safety features, ensuring stable system operation and longer, safer pump performance. The clear display and ability to calibrate the controller to a specific pump make operation simple, even for less experienced users.
Who it is for
- Installers and plumbers – the M121 controller simplifies the commissioning of a single pump through calibration tailored to the specific device and clear display-based operation.
- Homeowners with their own water supply – the controller automates the operation of a submersible or surface pump and protects it against costly failures.
- Farmers and allotment gardeners – the device monitors pump operation during irrigation and tank filling, responding to the water level in the water source.
- Users of systems with tanks – the controller switches the pump on and off according to the water level or pressure, streamlining the operation of the entire system.
Applications
The M121 controller is suitable wherever a single-phase pump needs to operate independently and reliably. It works with submersible pumps in domestic wells, surface pumps in household water systems, and immersion pumps in tanks and pumping stations. The on/off signal can be received from probes, float switches, or a pressure switch, allowing the controller to be adapted to various system configurations.
The device regulates pump operation according to the water level in the tank from which it pumps, the level in the destination tank, or the pressure value in the system. This allows one controller to handle both simple irrigation and more advanced filling and pressure-boosting systems. Pump control is provided by the M121 230 V electronic controller.
Features of the M121 controller
The heart of the device is an electronic system that continuously monitors pump operation and power supply parameters. The M121 offers dual dry-running protection – it simultaneously analyzes signals from probes or liquid-level sensors and the current consumption of the operating pump. After an emergency shutdown, the controller automatically attempts to restart the pump, with the restart time selected according to the type of fault. The device can operate in automatic or manual mode, depending on the system’s requirements.
The controller is housed in a durable plastic enclosure with a built-in LCD display, designed for indoor installation. The set includes measuring probes, so the device is ready to be connected in a typical installation. The key parameters of the series are listed below.

Frequently asked questions (FAQ) – M121 controller
What is the M121 controller used for?
The M121 controller is an electronic device for automatically controlling the operation of a single pump and protecting it. It switches the pump on and off according to the water level or system pressure and protects it against failures caused by dry running and incorrect power supply.
Which pumps can be connected to the M121 controller?
The M121 works with single-phase submersible, immersion, and surface pumps rated from 0.37 to 2.2 kW with a 1~230 V power supply. This makes it suitable for both deep wells and household water systems or tanks.
Does the M121 protect the pump against dry running?
Yes, the controller uses dual dry-running protection – it simultaneously analyzes signals from liquid-level probes and the current consumption of the operating pump. When a fault is detected, the pump is switched off and the controller automatically attempts to restart it.
How does the M121 controller differ from the M131, M21, and M31 models?
The M121 is designed for single-phase pumps, while the M131 supports three-phase pumps and additionally protects them against phase failure. The M21 and M31 models extend the functionality with an accumulated operating-time counter, a history of the last five faults, and a dynamic LCD screen displaying the pump’s current status. You can find the full range in the controllers category.
Can the M121 controller be installed outdoors?
The M121 has an IP 22 protection rating and is designed for indoor installation. In systems with a pump operating outdoors, the controller itself must be placed indoors or in a suitable protected enclosure.
Where can I buy the M121 controller?
As the manufacturer, we do not sell directly. The IBO M121 controller can be purchased from our trade partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the M121 controller?
IBO – 24-month (2-year) manufacturer’s warranty.
