Wiring The Pulsacoil Stainless 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 fitted
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 Stainless 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 Stainless When Only An
On Peak Supply Is Available
With this arrangement the dwelling has no
off-peak tariff available. We recommend that
a boost controller and immersion heater time
switch are fitted.
This will prevent the system being constantly
heated but leaving a boost facility available.
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.
