We just got a Bryant air conditioner/heat pump unit installed with a new Bryant Programmable Control Preferred Series Thermidistat. It controls heat and humidity.

The first week everything was fine. Then it started making loud clicks every time the heat came on and went off.

They are so loud that it wakes me up at night.

Its usally 3 loud clicks, right in a row.

Is it just this type or brand of Thermidistat? Or do you think it is defective? What is the solution?
