Immersion temperature sensor

Part no. 7426 247
For installation in the DHW cylinder, heating water buffer cylinder,
combi cylinder.
■ For DHW circulation diversion in systems with 2 DHW cylinders.
■ for return changeover between the boiler and the heating water buf-
fer cylinder
■ for heating additional consumers.
■ For a heat statement (return temperature is captured).
On-site extension of the connecting lead:
■ 2-core lead, length max. 60 m with a cross-section of 1.5 mm
