upgrade
Horstmann Controls has upgraded its widely used Electronic 7 immersion heater control to give it more contemporary look with a larger back lit display and incorporating updated electronics.
It is fully interchangeable with earlier versions of the controller so upgrading can be undertaken quickly using the plug-in connectors and without the need to change the wall mounted back box The new Electronic 7 is fitted with an automatic clock that is pre-set on manufacture and which automatically adjusts to accommodate GMT/BST summer/winter time changes

Programmable room stats from Horstmann Horstmann
Horstmann Controls has introduced a new range of ThermoPlus programmable room thermostats that break new ground for their ease and simplicity of use.
There is also a long life battery which will maintain the clock, display and switch time settings with the mains supply disconnected.
This should be sufficient to cover all unexpected interruptions during the life of the control.
Electronic 7 is compatible with all utility company tariffs that keep to Greenwich Mean Time (GMT) MSOfficeor that vary with British Summer Time (BST).
It allows for up to three secure off-peak heating periods every 24 hours, making maximum use of electricity when tariff's are cheaper.
The control retains the 1 hour boost button that permits the householder to activate a short term override of the set programme, permitting more hot water to be heated at any time by switching on the immersion heater for a short 'boost'.
Alternatively if it is known that extra hot water will be required every day, the 'boost' element (in the cylinder) can be programmed so that it will heat only a small part of the tank.
This is normally the upper immersion heater element and can be programmed to come on once each day at a set time.
Some utility tariffs offer additional cheaper electricity periods during the day time; the Electronic 7 has extra off peak switching periods available to accommodate these.
