Water temperature monitoring device e.g. for detecting maximum permissible water temperature for heat exchanger, provides cut-out of burner for heating water for safety protection of heat exchanger

摘要

Water temperature monitoring device has at least one sensor (11,12) associated with water feed line (10), providing output signal which is fed to control device (15) and comparator (18) receiving reference signal at one input and sensor output or second reference signal at other input, for providing output signal fed to second input of control device and used for controlling burner used for heating water.
