connect to the Off-Peak supply and CANCEL any remaining Boost period.
Pressing either of the Boost button 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.
The BX2000 has three indicating neons.
The OFF PEAKACTIVE indicator is illuminated whenever the Off-Peak supply to the immersion heater is
switched ON.
The 1 HOUR or 2HOUR Boost indicator is illuminated whenever the relevant Boost button is pressed
and the Standard Rate supply to the immersion element is switched ON.
SERVICE AND REPAIR
This programmer is NOT user serviceable. Please do not dismantle the unit.
In the unlikely event of a fault developing please contact a local heating engineer or a qualified
electrician.
ISOLATOR SWITCHES
The BX2000 has two built in double pole isolator switches labelled NORMAL supply and OFFPEAK
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.
