Horstmann's Electronic 7 immersion heater control
is instantly compatible with tariffs that keep
to Greenwich Mean Time and those that vary with
British Summer Time.
It allows up to three secure off-peak heating
periods every 24 hours, to make the maximum use
of cheap rate tariff structures - including split
tariffs.

|
One-minute accuracy means no accidental running
over into full-rate tariff periods.
Suitable for use with single, dual or twin element
immersion heaters.
