BOILER THERMOSTAT/THERMISTOR FUNCTION
The control thermostat on the boiler allows the householder
to vary temperature to central heating from a low of 60˚C
to 80˚C, depending on the model. Thermostats have a
tolerance of ± 4˚C.
In accordance with EU boiler standards, your boiler is also
fitted with a safety high limit thermostat, fixed at 110˚C.
This system protects the boiler in the event of the control
thermostat failing and keeps the boiler safe.
The safety high limit thermostat will shut the boiler off
and will require the limit button to be pushed to restart
the boiler. It is recommended to call a service engineer to
establish the cause.
BURNER LOCKOUT
The boiler is factory fitted with a burner control box
lockout safety feature which operates automatically if a fault
occurs in the burner operation. Should this occur, the light
on the front of the burner will illuminate.
Press the reset button a maximum of two times. If the boiler
fails to light, call a service engineer who should check the
following:
A. An interruption in the fuel supply
(eg. empty fuel supply tank).
B. An electrical supply fault.
C. A fault with the burner or its safety control system.
D. The failure of a burner component.
E. Worn or dirty fuel nozzle.
F. Incorrect flue installation.
Please consult with your installer regarding the operation of your boiler. This should include
timer operation/room thermostat operation and any other additional operational features.
The basic features of the control panel are outlined below.
