ELECTRONIC 7 SERIES 3 (E7) \ Electronic Immersion Heater Control, Heating Controls, Electric Water Heating
_Fully interchangeable with earlier versions using plug-in connectors
_No need to change the wall mounting box. Compatible with all utility company tariffs.
_Automatic clock adjusts to accommodate GMT/BST summer/winter time. Accommodates up to three secure off-peak heating periods every 24 hours.
_Long life battery maintains the clock, display and switch time settings throughout the life of the control. ÔBoostÕ button is ideal for short term overriding of the set programme.
_ÔBoostÕ element (in the tank) can be programmed so that it will heat only a small part of your tank at a set time each day. Can be set to accommodate utility tariffs that offer cheaper electricity periods during the day time.
Horstmann BX2000 Immersion Water Heater Controller
_Used to control electric immersion heater(s) that utilise an "Off Peak" ("Economy 7" or "Low Rate") tariff.. This unit requires two separate electrical supplies to it, one constant supply (from your "Normal" household Consumer Unit) and one timed supply (from your "Off Peak" Consumer Unit). It will control one, two separate or a dual immersion heater in the most efficient manner.
_During the off peak hours the controller will activate the immersion to store hot water at the cheapest rate. During the day time you can "boost" the level of hot water at any time by pressing either the One or Two hour boost buttons which prevents the heater being left on accidentally.
_Always gives priority to the off-peak supply and automatically cancels any boost that has been selected prior to the off-peak supply becoming available. One hour or two hour boost and cancel button. Indicator lights tells you which supply is active
_Incorporates two double pole switches: one for 24 hour supply; one for off-peak [low rate] supply. Requires two incoming supplies one from the Normal and one from the Off Peak. On systems with two immersions the boost supply will normally control the Top or Short element and the Off Peak controls the Bottom or Long element
_Maximum load is 3kW on each element (which is the standard UK rating). If you have the necessary two consumer units but only one cable running to the immersion heater at the moment it is possible that this Controller can be sited beside the Consumer Unit to derive the two supplies and the existing cable the feeds the immersion heater can be routed to leave this unit
