Secure BX2000 User Instructions
The BX2000 has been designed to provide greater flexibility to the consumer using Off-Peak electricity for Water heating. It provides the facility to Boost your Hot water at any time and to ensure you are automatically connected to the Off-Peak supply whenever it is available.
INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE IET WIRING REGULATIONS.
WARNING: ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION
Boost Facility 1 or 2 Hour
Whenever you require additional Hot water outside of an Off-Peak period, simply press either the one or two hour BOOST button.
for 1 hour of Hot Water
for 2 hours of Hot Water
The BOOST period may be cancelled at any time by pressing the CANCEL button.
The Boost will automatically switch OFF at the end of the chosen Boost period, ensuring that you use only the minimum of Standard Rate electricity required to meet your requirements.
Should an Off-Peak supply become available during a Boost period, the BX2000 will automatically connect to the Off-Peak supply and CANCEL any remaining Boost period.
Pressing either of the Boost buttons during an Off-Peak period will have no effect. Repeated pressing of the Boost buttons will not extend the Boost period.
Note: On systems with dual or two separate immersion elements, the Boost supply activates the short or top element. The Off-Peak rate supply activates the long or bottom element.
Neon Indicators
The BX2000 has three indicating neons:
- The OFF PEAK ACTIVE indicator is illuminated whenever the Off-Peak supply to the immersion heater is switched ON.
- The 1 HOUR or 2 HOUR Boost indicator is illuminated whenever the relevant Boost button is pressed and the Standard Rate supply to the immersion element is switched ON.
Isolator Switches
The BX2000 has two built-in double pole isolator switches labelled NORMAL supply and OFF PEAK supply.
When in the OFF position, they isolate the relevant supply to the immersion heater and switch OFF the associated indicator light.
If total isolation of the immersion element(s) is required, both switches should be in the OFF position.
For the unit to operate normally, both switches should be in the ON position.
