Description

Digital modular control and protection panel for 2 pumps up to 22A, 230 or 400 VAC selectable, control by external level sensor 4-20mA or float switches.

• Plug-in control module TZ2BS: simple adjustment and comprehensive status display.
• Greater safety for the user and better immunity.
• More interior space and more comfort.
