Wiring The Pulsacoil A-Class With Combined
On And Off Peak Supplies
With this arrangement the dwelling has a single
supply to the consumer unit from the meter
and the whole dwelling goes off-peak or on-
peak when the tariff changes at the meter. In
this case a single channel clock will need to be
fi tted in the off peak supply to the PulsaCoil. The
off-peak time clock will need to be synchronised
with the tariff times set on the meter and be
rated for at least 3kW at 230V.
Although the PulsaCoil A-Class appliance is
primarily designed to operate with an off peak
supply it will also operate quite successfully
if it is only supplied with an on peak supply.
However, this will substantially increase the
running costs of the appliance and should
only be considered if an off peak supply is not
available.
Wiring The Pulsacoil A-Class When Only An
On Peak Supply Is Available
With this arrangement the dwelling has no off-
peak tariff available. Because the appliance will
continuously sense the presence of a supply at
the bottom immersion heater (normally off-
peak) the controller will always use the bottom
immersion heater to charge the store and
boost will not be available unless the bottom
immersion heater fails.
To allow the appliance to operate successfully
with on peak only supplies, two separate 16A
230V 50Hz supplies MUST be provided with
one wired into the on peak connections in the
normal way and the other wired into the off
peak connections.
In all cases the two switches/isolators must be
clearly labelled for the householders use.
