This time switch allows the customer to shift electricity use into the 'off-peak' time periods in an attempt to save utility costs.

is the manual lever in on or off position for the automatic times to work

Asked by: habib
Once your adjustable on / off clips are in and the clock rotates, it'll turn itself off (and stay off) until the "start clip" kicks it on... The switch, at this point can be manually turned on for more hot water if needed, but again, the OFF CLIP, will flip the lever back to off..

wire melting?

I have had two of these at two different residences and after 5+ years of service the wires have melted at the connection terminals inside the gray box.
Asked by: JBird
Your wires should never melt. The only cause I can think of would be if you used a #14 wire and ran more than 15 amps thru it (same for #12 and 20A or #10 and 30A) What wire size are you using and what circuit breaker size?

clock does not move

I HAVE HAD ONE OF THESE WORKING FOR 20 + YEARS BUT NOW THE TIMER DOES NOT WORK TO TURN THE SWITCH ON. IS THER A FUSE IN IT TO MAKE THE CLOCK WORK OR DO I NEED A NEW ONE????????
Asked by: JOR
Simple, if the clock doesn't work, you need to purchase another one. There is no fuse to make the clock work.

Like the manual lever, again easy to turn on or off at "other" than selected times if needed. The only caution and this Clearly stated in the installation instructions is to Not try and switch the timer on or off manually 30 minutes before or after your set on or off time.

I have changed it twice and this time (3rd) the manual override switch became stuck to the cover. I had to adjust the switch handle, to stop it from being hindered by the closing of the cover.
