Temperature dependent control component for electrical circulating pump or electrical heater for required warm water provision in houses has external thermally conductive indicator of interior temperature

摘要

A temperature-dependent control component comprises a compact unit enclosing a temperature sensor, ideal value transmitter (6) actual-ideal comparator, signal element (7) and an electrical load power switch in a housing (1). The unit is directly fixed to a warm water tube (3) by, e.g., hose clips (2) and the outside tube temperature is determined through a thermally conductive piece used as an indicator of the internal temperature for the controller.
