Patent ID: 7112768

Claim:
A temperature control system for a bathing unit, the bathing unit including a receptacle for holding water and a heating module for heating the water supplied to the receptacle, said temperature control system comprising: a) a plurality of actuators associated to the heating module, said plurality of actuators being adapted for acquiring: i) a first set of actuation patterns causing the heating module to be in a non-heating state, said first set of actuation patterns including at least two configurations; ii) a second set of actuation patterns causing the heating module to be in a heating state, said second set of actuation patterns including at least one configuration; b) a temperature regulation device in communication with the plurality of actuators, said temperature regulation device operative for controlling said plurality of actuators such as to cause the heating module to be in either one of the heating state or the non-heating state, said temperature regulation device being adapted to select a configuration from the first set of actuation patterns for causing the heating module to be in the non-heating state, the selection being effected such as to alternate activation of the actuators in said plurality of actuators.
