Standard Equipment
The standard confi guration of the BoilerMate
2000 is shown opposite. The Appliance Control
Board (A.C.B.), mounted inside the appliance,
controls the operation of the complete system.
The A.C.B. is pre-wired to a terminal strip
where all electrical connections terminate. It
is supplied with the following factory fi tted
equipment:-
1. Boiler pump
2. Domestic hot water primary
(plate heat exchanger) pump
3. Space heating pump
4. Hard water appliance control board
(A.C.B.)
5. Electro-mechanical clock to control the
space heating (in conjunction with room
thermostat - if fi tted)
6. Plate heat exchanger
7. DHWS temperature sensor
8. PHE return sensor
9. Store temperature sensor
10. Y type strainer/fl ow regulator
11. A feed and expansion cistern
complete with ballvalve, overfl ow
fi tting and cold feed/open vent pipework
assembly is supplied separately.
Optional Equipment
* A soft water model is available for areas
where the hardness level is below 200
p.p.m. (mg/ltr)
* Flexible connectors for quick
connection to fi rst fi x pipe installation.
For further details see 2.2 Installation,
Pipework connections.
* 'Switch' emergency electrical back-up
for heating and hot water in the event
of a boiler fault.
* A seven day digital clock/programmer
to control the space heating (in
conjunction with a room thermostat if
fi tted).
* A kit to site the clock/programmer
remotely.
* A no clock option - because of the
design of the appliance it should not be
necessary to fit anything other than a
single channel clock to control the
heating system.
* Hot and cold water manifolds for use with
plastic pipework.
