Weather Compensation Kit - Installation
INTRODUCTION
This kit provides the facility to apply outside air temperature control to the boiler water ow temperature which provides
energy savings. The outside sensor provided measures outside air temperature and sends a signal to the boiler, which
adjusts the maximum boiler ow temperature in response. If outside air temperature is greater than the system design
temperature, the boiler ow temperature is reduced providing running cost savings. The boiler will operate in the
condensing mode more frequently increasing savings.
Once the sensor is tted it is automatically detected.
The sensor operation may be congured by adjustment of the boiler operating parameters, if necessary.

IDEAL BOILERS LTD
I certify that this boiler is connected to a weather
compensation temperature sensor which is
compatible with the boiler and provides weather
compensation control that has been
permanently enabled. The boiler has been
commissioned in accordance with manufacturer
instructions, which have been supplied to the
householder. The central heating temperature
control knob should normally be set in the
mid-position.

2 FITTING THE KIT
Notes.
1. A timer should be tted to the system so that CH will be
switched off when appropriate.
2. The Connector (Frame 1, item C). is pretted to certain
boilers. Boilers that don't have this tted are marked with
an * on page 2.
FITTING THE SENSOR
The air 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 air
sensor should be located to avoid any heating effect from the
boiler ue.
To x the air sensor to the wall, unscrew the sensor box plastic
cover and screw/plug the sensor body to the wall.
Wire a twin core 0.5mm2cable from the sensor to the boiler
through a RH grommet located on the underside of the boiler.
Cable length between sensor and boiler should be no greater
than 20m. Note that this connection is protected extra low
voltage. It is not necessary for the person carrying out the
wiring to be approved to Part P of the Building Regulations.
Avoid running this cable alongside mains voltage cables.
WIRING THE WEATHER COMPENSATION KIT TO THE BOILER
1. Isolate the electricity supply to the boiler.
2. Remove the boiler front panel (refer to boiler installation
instructions).
3. Hinge down the control box.
4. Unclip and rotate the installer connections cover towards
you until it clips into the retention holes.
5. Connect the wires from the outside sensor into the RHS
two terminals of the 4 way connector. Insert the connector
into the socket marked 'OPENTHERM / WEATHER
COMPENSATION'
6. Re-assemble in reverse order.
7. Record your name and today’s date on the enclosed label
and adhere it to the boiler in a position which will be visible
for future inspection.

CH OPERATION
The On and Off time control of central heating should be
controlled by a separate timer.
During programmed On times the Central Heating Radiator
Flow Temperature is controlled by the boiler relative to the
Outside Temperature as shown in the diagram.
The Room temperature can be adjusted using the Central
Heating Temperature Control Knob on the boiler as follows.
Essentially rotating the knob clockwise increases the room
temperature and rotating the knob anti-clockwise decreases the
room temperature.
The Room Temperature Setpoint in the associated graph is
not directly related to the Actual Room Temperature but is the
Nominal Room Temperature during a programmed CH period.
This can be adjusted between 5 and 30 degrees by the
CH Potentiometer Knob on the Boiler when the Outside
Temperature Sensor is connected. The graph only shows
temperatures between 12 and 30 degrees for clarity.
Examples:
1. If the CH Potentiometer Knob is set to display 22ºC on the
Boiler Display the Room Temperature Setpoint will be 22ºC
and the curve 22 will be followed, indicated by 11th curve
in from the left hand side. So as the outside temperature
varies the Flow Setpoint to the CH circuit will increase and
decrease proportionally.
2. If the CH Potentiometer Knob is rotated fully clockwise, the
Boiler Display will read 30ºC and the Room Temperature
Setpoint will be 30ºC hence the curve 30 will be followed.
3. If the CH Potentiometer Knob is rotated fully anticlockwise,
the Boiler Display will read 5ºC and the Room Temperature
Setpoint will be 5ºC. This is an unrealistic Room
Temperature Setpoint for a CH period during an ON time,
but it is calculated internally for managing Frost Protection
for the system based upon Outside Temperature.
DHW OPERATION
When the system is in a timed on period for DHW and the tank
stat is not satised, OV will be generated on the switched live
input SL2 of the boiler.
This will ensure that Weather Compensation adjustment is
ignored at this time. The set point will be xed at 80 degrees.
The demand is indicated on the display by ‘ON’ and the burner
on symbol as appropriate.
