Abstract

The thermostat uses the electro-thermal actuation of a valve controlling the hot water feed. An 'L' shaped bi-laminate (6) is mounted in a housing (4) on a section of the feed pipe (1). The leg (8) is bolted (7) to a housing wall, and the bar (6) extends to bear on a valve (2) actuating plunger (3). The bar is actuated by a heat sensitive resistance (14), the pressure it applies to the plunger (3) being adjustable, and the forces applied by the plunger being partly offset by an adjustable buffer spring (10). Effective buffer pressures may be adjusted using a simple screw jack (11, 12).
