These timers are great when your application calls for an accurate, reliable timer at a reasonable price. The timers are versatile and rugged making them well suited to both indoor and outdoor control panel installations where dependability is important. Simple to understand and wire, we have experienced a zero failure rate for the various installations we have used these timers in over the past several years.
My Favorite Feature Well price with high dependability
Pros: simple, reliable
Yes, I recommend this product.

We have used the 821TD10H on several critical applications and found it to be dependable.
Application example #1: holding a smoke damper open for 10 seconds to let a 50 Hp fan freewheel down a bit before slamming the damper closed.
Application example #2: pipe freeze protection by toggling a hot water loop circulation pump once per hour in an unoccupied vacation home in northern NH, whenever the outdoor air temperature falls below 20 degrees (which is often).
Pros: Good value, wide span of time adjustments in one device., slim takes up little space.
Yes, I recommend this product.

This is a special purpose product I have used in the past. However, my most recent purchases have proved unsatisfactory. Of (4) purchased (3) failed to work properly within just a few weeks. Recommend using the IDEC branded equivalent.
Cons: Low value
No, I do not recommend this product.
