2.2 INSTALLATION
Wiring the System
A printed circuit board (ACB) controls
the complete system and all the internal
components are prewired to this board, as
shown on the Appliance Wiring Diagram on
the previous page.
The details of the arrangement and
requirements for the external wiring are
shown on the Wiring Guide Diagram in
Section 1.3 System Details and Section 2.1
Site Requirements. Check the supplies comply
with their requirements.
As shown opposite, a heavy duty electricity
supply is required for the ElectraMate 2000
and therefore a qualified electrician must
carry out this work. The electrical installation
must comply with the IEE requirements
for electrical installations (BS7671) and the
requirements of the Local Electricity Supply
Company.
All the terminals are suitably labelled.
Note : Do not attempt the electrical work
unless you are competent to carry it out to the
above standards.
Connections to the electrical supplies must
allow complete electrical isolation by installing
double pole isolators.
The isolators must only serve the ElectraMate
2000 space heating and hot water system
together with its controls.
The use of Type ‘B’ circuit breakers to BS EN
60898 is recommended.
Before commencing the wiring, ensure that the
power source to which the ElectraMate 2000 is
to be connected is isolated and checked with
approved and certified test equipment.
Remove the front panel.
The appliance is supplied with a 3 metre x
10mm² mains supply cable and a 3 metre
x 1.0mm² low current off-peak signal cable
which should be connected via the slot/
grommets provided at low level on the
appliance to the relevant local isolators
provided as shown opposite.
To wire the Programmable room
thermostat :
Remove the link between terminals 26 and
28 on the terminal block (see opposite)
From terminal 26 take a ‘live’ to the ‘live
common’ on the programmable room t/stat.
From the programmable room t/stat ‘3 N/O’
connection take a ‘switched live’ to terminal
28. Connect one end of your earth cable to
terminal 25 at the appliance and connect the
other end of your earth cable to the earth
terminal on the programmable room t/stat
metal back box.

1. Appliance requires 24hr 45amp supply.
2. This unit also requires a low current off peak signal synchronised with a low
tariff period.
3. The diagram above shows the radio telemeter with two switched live outputs.
4. The domestic supply is fed via the permanent live which is logged on tariff 1
on-peak and tariff 2 off-peak periods.
