1. Turning The Boiler ON
Ensure the electrical supply to the boiler is turned
on. This may be from a switched socket or a fused
spur located near the boiler. This switch should be
left ON continuously to operate the boiler.
Turn the boiler ON by turning the ON/OFF control (5)
from the ‘0’ position to the ‘I’ position.
2. How to control the heating
The radiator temperature control (2) sets the
maximum radiator temperature.
Check that the remote programmer is in an on
setting (see separate programmer instructions) and
check that the room thermostat is calling for heat.
Your heating should now operate. It will remain on
until either the timer shuts off or the room thermostat
is satisfied (room is at set temperature). To turn off
the heating operation, turn the radiator temperature
control (2) fully anticlockwise.
3. How to control the hot water temperature
Your combination boiler will start to produce hot
water as soon as a hot tap is turned on. The
temperature of the hot water can be controlled by
the control knob (1). The temperature range can be
adjusted from a minimum of 35°C to a maximum of
approximately 60°C. Rotate the control knob
clockwise to increase the temperature and anti-
clockwise to reduce the temperature. The value will
be briefly displayed on the boiler display (3).
