Available fixed 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 o-peak electricity is not available, resulting in larger bills.
NOTE:
The property energy supplier should be consulted to confirm that the meter and tari is suitable for

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, digi-
tal charge times should be set with an hour buer at the start and end. Most Dimplex 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
tari this should not cause an issue.
Smart meters may adjust for DST with server times, in which case this would not be necessary.
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
The mains cable should be stripped to a length of 8mm allowing 10mm extra for cutting o/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.
