Immersion heater control
Electronic 7 is the digital equivalent of the Economy 7 Quartz timer, and is designed for use with Economy 7 and other more recent cheap-rate tariff arrangements. When water is heated by off-peak electricity, it is important that the immersion heater controller offers ease of use, coupled with the most efficient performance. This is where the Electronic 7 Series 3 controller comes into its own. Electronic 7 is designed to control one or two 3kW immersion heaters, utilising off-peak electricity tariffs to provide a full tank 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 hot water if supplies run low, and an automatic boost setting to provide a preprogrammed daily boost is also available.
