There are some type of timers that can be locked into the off or on position. Flick the power to the timer off and then on within 10 seconds. If the lights come on do nothing. The daylight photo cell will shut them off automatically. If the timer is not that type then state more detail on the discussion page.
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
First you need to decide what you are trying to accomplish. You can wire the Timer switch in series with or parallel to the 3-way switches. If in series then the 3-way switch function would depend on the timer state. If the Timer switch was ON then the 3-way switch could turn the connected device ON or OFF from either location. If the Timer switch were OFF the device would be OFF no matter what you did with 3-way switches. To wire in this fashion put the timer between the supply and the input to the switches. If the Timer is in parallel then if the Timer is ON it doesn't matter what you do with the 3-way switch, the device will be ON as long as the Timer is ON. If the Timer is OFF then the 3-way switches will work in their normal fashion. To wire in parallel connect the supply to one side of the Timer and the device to the other.
Fridge timer probably needs to be replaced!
No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.
Yes, an electrical timer can be used to control the on and off operation of the power to self ballast lamps.
it means you left the power on too long
call a plumber
with an ON delay timer once the power has been appied to the timer unit, the timer contacts will change state-open/close after a preset time (for example A&B timers are adjustable anywhere from 0.05 seconds to 300 Hours) with a OFF delay these contacts change state after the power to the unit has been removed then the preset time will time out (this count dosen't start until the power is removed

Sprinkler irrigation systems irrigate (water) crops/plants. If it is automated with a timer, sprinkler irrigation systems can be turned on and off at different times of the day. Places you'd find automated sprinklers: Parks, golf courses, landscapes, etc. Sprinkler irrigation systems can also be found on farms in several different formats, including pivot systems, pipes laid through fields (hand-lines), and wheel-lines.
A modern X-ray machine is turned on-and-off by a timer-operated electrical switch. The power is turned on when the operator presses a start button and is turned off automatically by the timer. This is done to reduce the likelihood of operator error.

Go to Diamond Mines if you aren't already there. Go to the way right and the timer thing is there. You need a hard hat to go there though. Move quickly after you turn off the electricity.
The difference is that one is on and the other is off.

A programmable timer usually just means a timer that can be programmed to go off at any time.
