1) Heating Temperature Control
The heating temperature control
adjusts the temperature of the central
heating water flowing from the boiler
to the radiators. Turn the dial
clockwise towards red to increase the
temperature
and
anticlockwise
towards blue to reduce.
2) High Limit Reset
The high limit thermostat protects the
boiler against overheating and is
factory set to 110°C (not adjustable).
Should this thermostat ever trip, it
must be reset by pressing the small
red button underneath the control
panel towards the left hand side. Do
NOT reset when the boiler is still hot.
3) Hot Water On/Off Switch
4) Heating On/Off Switch
Heating and Hot Water modes are
controlled via the on/off switches
unless a remote time clock has been
fitted. Consult your installer.
5) Mains On Lamp
If this lamp is not lit there may be no
power coming to the appliance.
Check fuses and heating controls.
6) High Limit Lamp
If this lamp is lit, the high limit
thermostat has tripped. Press the
high limit reset (2).
7) Burner Lockout Lamp
If this lamp is lit, the burner has
locked out after failing to fire. Press
the red reset button on the front of the
burner.
8) Low Pressure Lamp
If this lamp is lit, the system pressure
has fallen below 0.3 bar. Refer to the
instructions in Sections 1.4 and 1.5.
Additionally, top up the pressure until
the light goes out then release
pressure via the pressure relief valve
until system pressure is 1 bar when
the boiler is cold.
