Following link has manual for Intermatic ET8100 series
Choose astronomic dawn-dusk timer -or- 7-day programming
http://waterheatertimer.org/Intermatic-ET-series-timers-and-manuals.html#ET8000

be sure to install two AAA batteries in compartment located on front just below the buttons.
Also reset the timer prior to programming ... and this will clear any conflicts or prior programming.
Timer default voltage is 120 volt AC. Choose 208-240-277 volt by moving selector switch located on back of timer.

LP126HD3A rated for 265 volts AC single phase I have 240V ac single phase, how can I use this unit on 240V ac


You'd need to supply a "Buck-Boost" transformer to do this properly. Technically, the 265 VAC is one hot leg and neutral of a 480 VAC 3 Phase Y system that measures 277 VAC. The 265 number comes from this:

265 is the standard nameplate voltage for a 277 volt motor or AC unit.

230 is standard name plate for 240.
200 is standard name plate for 208
460 is standard name plate for 480.
110 is standard name plate for 120.

Most electricians call the hot leg / neutral circuit "277V AC".

Some popular "Buck-Boost" transformers will convert 208 to 240 and 240 to 208 volt systems, and 240 to 277 and 277 to 240 volt systems - among many other variations. These are auto-transformers as the primary secondary windings share a connection. KVA ratings differ significantly from name plate because of this fact. You should contact a qualified electrician to not only size, but wire the transformer for you. Failure to install a Buck-Boost transformer - and running this unit on 240V AC mains will cause premature failure of motors - fans and compressor due to overheating. This can also result in a fire hazard.

I hope this helps and good luck!

Hello i have an intermatic model #t104r 208-277 volt my problem is that it works manually but it doesnt work automatically? whats wrong?


If you can also manually turn the dial so that the load turns ON and OFF, then the timer motor is bad :-( Replacements are available here for about $30:

Can you use 16g s/o cord from the j-box to a 2x4 highbay fixture. the voltage is 277 volt & is a fluoresent fixture.


The voltage is OK for the SO cord .. but since it is a field installed cord it needs to be sized for the amperage rating of the circuit supplying the fixture .. #12 for a 20 amp circuit, #10 for a 30 amp circuit etc.
