Modular control and protection panel for 2 single-phase or three-phase pumps up to 12A with automatic alternation between them by means of an external 4/20mA level sensor or floats, 230/400Vac power supply (selectable). It allows the manual adjustment of the maximum intensity of protection against overload, as well as the adjustment of the high and low levels for level control by means of floats and/or 4-20mA level sensor or conductive probe (optional module for installation on the terminals of control).

It offers built-in pump protection against overload, lack of phase (three-phase pumps), motor overheating (three-phase pumps-Klixon input) and anti-seizure protection so that when the pump is in automatic state, the unit applies one second of running every 23 hours of inactivity, to avoid seizing and deterioration in long periods of rest. Automatic switching of the pumps due to failure or deactivation of one of them.

Integrated high level light and acoustic alarm voltage-free output of 90dB. The activation of the alarm contact can be caused by power failure, pump failure, high level, no pumps in AUTO, sensor failure. Compatible with Toscano brand PumpCheck data reader.


The TZ2BS control module, which is included in the modular panel, allows quick and easy adjustment of the intensity for overload protection, as well as the adjustment of the high and low level at which the alarms must be activated. Its display allows you to show data such as the status of the pumps and their current consumption, operating time, detected faults and alarms. It also has pilot lights indicating the presence of voltage, pump operation, infrared communication (PumpCheck), overload states or phase failure, high level. The reduced size of the TZ2BS control module allows for greater interior space and greater comfort inside the frame.

The panel has a load cut-off switch for forced stopping that stops the motor and does not allow it to start under any circumstances, as well as two selectors for operation in manual or automatic mode for each of the pumps. In the manual mode of operation, the pumps are not protected against any type of fault.


Wall mounting by direct fixing by screws or by means of claws.


Operating modes using buoys:


NOTE: In the operating mode with a 4-20mA level sensor, it must be connected to terminals "10" and "11".

Panel connection:




NOTE: A jumper must be placed to select the desired supply voltage. Consult instruction manual.

NOTE: For the connection of a 230V three-phase pump to single-phase current, it is necessary to create a false phase to enable asynchrony in the three-phase system. To do this, a capacitor is connected between one phase and the tip of the winding that remains without power.
