Thermostatic device having two regulating conditions and two thermostatic elements

A thermostatic device having two regulating conditions, said thermostatic device comprising:

• a body defining a chamber having a first outlet port, a second outlet port, a first valve seat surrounding said second outlet port, and an inlet port;
• a casing in the form of a pipe having an inner end disposed in said chamber, and a second valve seat formed at the inner end of said pipe and surrounding the first outlet port,
• a thermostatic fluid-metering element disposed in said casing and having a moveable fluid-metering component that includes two valves and is movable in said chamber,
• wherein said valves cooperate with said first and second valve seats, respectively, so that when one of said valves moves away from its respective valve seat, the other of said valves moves towards its respective valve seat,
• wherein said moveable fluid-metering component is movable with respect to a part of said thermostatic fluid-metering element, which extends at least partially outside of said chamber;
• and
• a thermostatic threshold-setting element disposed in a part of said casing located outside of said chamber, said thermostatic threshold-setting element having a moveable part carrying a moveable threshold-setting component provided with a moveable stop that cooperates with the part of said thermostatic fluid-metering element that extends at least partially outside of said chamber,
• said thermostatic threshold-setting element having an electrical heating device adapted to be electrically connected to an electrical power supply that can be selectively activated and deactivated so that, when said thermostatic threshold-setting element is not heated, the distance between the movable stop and the first valve seat is less than when said thermostatic threshold-setting element is heated.
