Data Sheet

Electronic 7 Series 3
The Electronic 7 is designed to control one or two 3kW
immersion heaters, utilizing off peak electricity tariffs to
provide a tank full of hot water each morning.
Additional off peak settings are available to take
advantage of the latest off peak tariff arrangements.
A boost button is provided to top up the hot water if
supplies are running low and an automatic boost
setting to provide a pre-programmed daily boost is also
available.
The Electronic 7 Series 3 is interchangeable with
previous Economy 7 controllers using the standard size
Economy 7 wall box and plug in connectors.
A lithium battery provides more than adequate back up
to maintain time and programme settings in the event of
a power failure.
