Electronic meter for heating costs containing circuit board and sensors in casing, includes thermal insulator which intervenes between front and rear sections of casing

摘要

The casing (2) has front- and rear- (3a, 3b) sections enclosing a circuit board (4). Two sensors are mounted on the board (4), comprising a room air temperature sensor (5) and a heater temperature sensor (6). A thermal insulator (14) intervenes between front and rear of the casing.
