Available !xed charge times must be manually programmed into the heater to tell it when to charge; no external timers or
contactors are needed. Up-to 4 digital charge times can be set.
If charge times are not programmed into the heater, the default times will be used which are set-up by default to support dual-
supply installations: 00:00 – 00:00 or 24h charge window.
A 24h charge window in a single supply installation will cause the heater to charge continuously, including
times when off-peak electricity is not available, resulting in larger bills.
NOTE:
The property energy supplier should be consulted to con•rm that the meter and tariff is suitable for single supply

Not all single supply meters adjust for Daylight Savings Time (DST). If DST is enabled on the heater then the digital charge
times will adjust automatically. When installing with a meter that does not adjust for DST, digital charge times should be set
with an hour buffer at the start and end. Most Heatstore storage heaters can fully charge within 5 hours and the automatic
charge calculation may not always take a full charge so on an E7 or E10 tariff this should not cause an issue.
Smart meters may adjust for DST with server times, in which case this would not be necessary.
Online / ‘Connected’ installation
Fixed Off-Peak tariffs
This type of installation is the same as the offline installation above, but the heater’s internal clock will be synchronised with
the Heatstore Control cloud server; preventing time drift and removing the need to check the heater’s clock annually.
Variable charge time tariffs
Some energy suppliers offer variable off-peak tariffs that can work specifically with Heatstore Control supported storage
heaters. In this kind of installation, digital charge times do not need to be manually programmed into the heater, the energy
supplier will do this automatically via the Internet and Heatstore Control platform.
NOTE:
As this installation relies on the accuracy of the heater’s internal clock, it is good practice to check the clock
annually and re-adjust if necessary. All clocks are subject to time drift and some can be up to +/- 3 sec per day
NOTE:
If connectivity is lost in this set-up, the heater will automatically change back to the ‘of!ine’ or ‘non-variable’
charge times that the energy supplier sent to the heater during setup. The supplier should recognise that the
heater is charging within "xed charging times and charge the appropriate rate. If there are any discrepancies, the
energy supplier should be contacted.
The mains cable should be stripped to a length of 8mm allowing 10mm extra for cutting off/trimming. Twist the stripped cable
slightly and then trim to a length of 8mm, folded over and inserted into the receptacle with no insulation trapped and likewise no
conductors showing, hence why the strip length is critical. The terminal block screw should tighten down onto the formed loop
and not cut through it.
Ensure that the terminal block is not tightened on the cable insulation as this may
lead to local overheating at the connection which may lead to a hazard.
CAUTION
The terminal block should be tightened to a minimum torque of 2Nm and a
maximum torque of 2.2Nm.
