Intermatic T104-20 Mechanical Water Heater Timer

Utilities in many areas of the country offer two electric rates for
residential or commercial customers. One rate has the regular
daytime electrical rate, the other is the “off-peak” rate. The “offpeak”
rate provides customers with “lower-priced” electricity during
the nighttime and weekend periods. These time switches allow the
customer to shift electricity use into these “off-peak” time periods in
an attempt to save utility costs.
