110V Timer Switch 25A,7 Day programmable Seconds Timer;Time Switch Relay,Digital,28 Programs,on Off,Electric 120 Volt,20 amp

This is a vine review meaning the product was provided to be reviewed.This product is a digital timer switch intended for 110 V applications. An instruction pamphlet is included. The product is packaged in a brown card stock box.This product was reasonably simple to program using the included instructions. It is important to actually follow the instructions, particularly to unlock the unit which requires four presses of the unlock key, which is typical for Chinese timers. A provision for back up power for the digital timer only is provided by a single AAA battery (not included). The battery will not operate the product’s relay.I ordered this product to control the electric water valve for my furnace humidifier. Unfortunately, I did not realize 110 V is required to throw the relay inside the product. The 24 VAC feed from the furnace is insufficient to operate the relay.Since the product description mentions this is 110 V timer, it is my error for ordering a product that would not work in my application.
