The Powersaver Dual is an immersion controller to be used with low-rate electricity tariffs. It helps to keep electricity costs down and ensure installation
is fast and painless:

     these program times cannot be changed by the user.

  There is a programmable boost function available that gives a maximum
     of 2 hours boost to ensure expensive electricity is not wasted.

  Designed as a direct upgrade of Sangamo Quartz 7 and Horstmann Quartz 7.
