INSTALLATION

15 MAINS ELECTRICAL CONNECTIONS

1. The appliance MUST be wired with a permanent live supply.  Use the plug 'A'

provided for this purpose.  The mains supply must meet with the regulations in
Frame 14.  The boiler is phase sensitive so correct connection of the live and
neutral wires is essential.  The supply must not be interrupted by any system
controls.  Controlling the mains input in this way will prevent the pump over-run
sequence and may cause damage to the heat exchanger.

2. A system pump must be connected to the boiler via a relay to ensure pump over-

run.  A 230V AC output is provided for this purpose on terminals 11, 12 & 13.

16 CH CONTROLS CONNECTIONS

Note.

For some of the optional control methods it will be necessary
to access the parameter mode.  This is done by entering the
Service Code described in  Frame 26 and must only be
performed by trained installers and Service Engineers.

1. Timer/Thermostat with Optional Weather Compensation

The boiler can be operated with a timer and/or room
thermostat.  Terminals (5 & 6) with a 24V supply and return
are available to be switched, open/closed circuit, by a timer
and/or room thermostat.  The boiler senses open circuit as
no call for heat and closed circuit as call for heat.  Mains
voltage MUST NOT be applied to these terminals.  Optional
fitting of the outside sensor (provided with the boiler) to
terminals 3 & 4 is automatically detected.  The flow
temperature is then compensated against outside
temperature in CH mode.  See frame 34

 

for details on the

specific behaviour of the boiler with this control and how to
modify the heating curve.

2. Outside Sensor with Night Time Set Back

The boiler can be operated with a permanent call for heat,
with the flow temperature compensated against outside
temperature in CH mode.  It is necessary to change
parameter A 1st digit to '1x' see Frame 29.  The outside
sensor (provided with the boiler) should be connected to
terminals 3 & 4.  To control the night time setback period
(period of lower room temperature) a timer should be
connected across terminals 5 & 6.  These terminals
provide a 24V supply and return to be switched open/
closed circuit.  Open circuit enables the night time set back
period.  If no night time set back period is required then a
link wire should be placed across terminals 5 & 6.  Mains
voltage MUST NOT be applied to these terminals.  See
Frame 35

 

for details on the specific behaviour of the boiler

with this control and how to modify the heating curve.

3. BMS Control

The boiler can be operated using a BMS control.  It is
necessary to change parameter A 1st digit to '2x' see
Frame 29.  A BMS can be used to operate the boiler using
a 0-10V signal to control the set flow temperature.  The
positive signal from the BMS should be connected to
terminal 9 and the ground signal to terminal 10.  An alarm
signal in the event of a lockout is available to the BMS from
terminals 14 & 15.  In the event of a lockout the boiler
closes the circuit between these terminals.  A link wire
should be connected between terminals 5 & 6.  Open
circuit would enable the parallel shift controlled by
parameter 7.  See Frame 35

 

for details on the specific

behaviour of the boiler with this control, and how to modify
the relationship between signal voltage and set flow
temperature.

Note.

Fitting the Outside Sensor

A. The sensor should be located on an external wall of the

building to be heated.  Fix the sensor to a north/north-east
facing wall to avoid direct radiation from the sun.  The
sensor should be located to avoid any heating effect from
the boiler flue.

B. To fix the sensor to the wall, unscrew the sensor box plastic

cover and screw/plug the sensor body to the wall.  Wire a
twin core 0.5mm

2

 cable to the sensor via cable gland

provided.  Avoid running this cable alongside mains
voltage cables.

C. Connect the emc filter provided with the sensor to terminals

3 and 4 in the boiler.  Connect the cable from the sensor to
the emc filter.  The connections can be made irrespective
of polarity.

Note.

All 230V wiring and 24V wiring MUST be kept
separate.  For this reason separate conduits are
provided for bringing wiring into the boiler.
