Night rate is 11:30pm to 7am EST (so that's 12:30am to 8am EDT in the summer). The ETS units can be set to use night rate electricity using the controller which is the small tan box in the garage, just right of the fuse box.
After following the steps below, the heaters should be set to turn on at night.
Double check the settings when you are all done. If the heaters are set to turn
on at 1am and off at 5am, then the button sequence
"Clock, On, On, Off, Off, Clock"
should produce this sequence on the display,
"current time, e 0100, - ----, e 0500, - ----, current time"
If the heaters are set not to turn on, then the button sequence
"Clock, On, On, Off, Off, Clock"
should produce this sequence on the display,
"current time, - ----, - ----, e 0500, - ----, current time"
