Save an additional 5% to 12% in energy use by installing the NSI DTWH40 time switch to control an electric hot water heater. This digital, 7-day timer is designed to be set to repeat a schedule from Monday to Friday, plus automatically allow a later schedule for the weekends. The timer comes with an override button on the case. With this unit, you can limit the operation of the heater to just a few hours in the morning and the evening. Thus, the water heater will not be operating all day and all night non-stop, but only when needed. On each day of the week the NSI DTWH40 offers 7 ON/OFF pairs of set points for individual programs. You can set it for one minute minimum and maximum time setting of six days, 23 hours, 59 minutes. Reduce energy cost with the NSI water time switches.
