Balanced force control cable assembly

A cable assembly for rotating a temperature control device in response to a rotating input, comprising:

• a first housing,
• a first lever rotatably mounted to said first housing for rotating in a first operating range and for receiving a rotating input,
• a second housing,
• a second lever rotatably mounted to said second housing for rotating in a second operating range and for attachment to a temperature control device,
• a cable engaging and extending between said first and second levers for rotating said second lever in response to the rotation of said first lever,
• a first spring engaging said first housing and said first lever for applying a first constant force to bias said first lever to rotate in a first direction under said first constant force throughout said first operating range of said first lever to apply a predetermined tension force on said cable, and
• a second spring engaging said second housing and said second lever for applying a second constant force to bias said second lever to rotate in a second direction under said second constant force opposite to said first direction to counterbalance said first spring and maintain tension in said cable whereby said first and second levers remain stationary at any point in said first and second operating ranges.
