Multibox Mini DX, white - Flush-mounted underfloor heating controller with thermostatic head K 9305-00.800

Compact controller for individual heating control

Multibox Mini DX is an advanced concealed controller designed for precise temperature control in individual rooms with underfloor heating, wall heating, and mixed radiator-floor systems. Thanks to its compact design with a mounting depth of only 60 mm, it is ideal for installations with limited mounting space.

Intelligent adaptation to mounting conditions

The system has been designed for easy installation even in difficult construction conditions. The masking cover compensates for mounting deviations of up to 4° on each side, eliminating problems resulting from inaccuracies in wall execution. Additionally, the possibility of depth compensation up to 30 mm between the box and the cover allows for universal mounting in all types of walls — from concrete to timber frame.

Precise regulation without power supply

The DX thermostatic head acts as a proportional (P) controller without the need for power, offering a setting range of 6°C to 28°C. The system is equipped with V-exact II stepless precision adjustment, which enables hydraulic balancing of the installation — crucial for the optimal efficiency of the entire heating system.

Durable construction and easy operation

The valve body is made of corrosion-resistant bronze, and the stainless steel stem is equipped with a double O-ring seal. A particular advantage is the ability to replace the external O-ring without draining the installation, which significantly simplifies service work and minimizes system downtime.

Universal connections

The controller is equipped with a G3/4" Eurocone connection, which enables the connection of pipes:

• Plastics (PE-X, PE-RT)
• Copper
• Thin-walled steel
• Multilayer (pex-al-pex)

All external elements are finished in white RAL 9016, ensuring an aesthetic appearance that fits most modern residential and commercial interiors.
