Description

LK 420 MiniShunt 2.0 is a shunt group intended for use when smaller underfloor heating areas are to be connected to an existing heating system. LK MiniShunt adapts the heating system temperature to the lower temperature necessary for the underfloor heating system. Its capacity can normally be set at a heating need of 50 W/m² to a maximum 60 m² underfloor heating area. Capacity is however dependent on primary temperature, pressure, laying method etc.
• For underfloor heating areas up to 60 m².
• Compact design.
• Energy efficient circulation pump.
• Thermostat-controlled maximum limit of supply temperature.
• Switchable between single or twin pipe systems.
• VF valve.
• Easy filling and air bleeding.
• Expandable to 2, 3 or 4 underfloor heating circuits.

Items Included:
• Circulation pump Wilo Yonos Para RSB 15/6-RKA, with automatic speed control, 1 fas 230V AC, 50 Hz, max 45W, 0,44 A.
• Thermostat with capillary tube sensor, length 2 m.
• 1 thermometer to place in one of the shunt group’s thermometer pockets.
• Hose 0.5 m for air bleeding.
• Primary connector G20 EK and 2 connectors for CU15.
• Bracket.
