    This new timer is quieter than the old on it rplaced. However, this new timer is still noisy enough to hear while one is in bed trying to go to sleep.

    Replaced old like units that had functioned well for approx. 14 years without a glitch. Long lasting dependable timer switch. I use it for heated floors.
