ELECTRAFLOW CONTROLLER
USER INSTRUCTIONS
INTRODUCTION
This Controller has been specifically developed for the Electraflow heating system to
efficiently provide you with both hot water and central heating at times tailored to meet the
needs of your household.
Through the night, water in the storage cylinder will be heated by low cost off-peak electricity,
available for use the following day. Depending on your hot water requirements, there should
normally be sufficient to last the whole day. Further hot water can be quickly obtained by
using the hot water Boost feature. The Boost will re-heat the hot water for a fixed period.
The central heating is heated by an electric boiler. The Controller provides a 7-day
programmable timer to turn on the central heating, up to three times each day of the week.
For your convenience a heating Advance feature is also provided to allow easy extension of
the programme times.
USER CONTROLS
The Controller has a backlit display and two LED indicators to show the system status during
normal operation. The display is also used to change the controller’s settings via an easily
accessible configuration menu.
During normal operation, the Boost key is used to enable hot water Boost and the Up key is
used to enable the central heating Advance feature. The Left key is used to set the CH
mode of operation and the Right key sets the HW mode.
