The temperature control knob gives you control
over the water temperature in your central heating
radiators, and you can adjust it to any position
within the indicated range (as shown in Fig. 2).
Higher settings obviously mean hotter
radiators and rooms will reach the required
temperature quicker. The ideal setting varies from
property to property, and can only be established
by trial and error and experience: a setting of
medium to high should serve as a good initial
guide.
PLEASE NOTE: The control knob must not be
set below the first indicating bar.
Your boiler is fitted with a high limit thermostat to protect the
appliance in the event of a control or system malfunction.
The manual reset thermostat will operate if the boiler reaches a
dangerous temperature. This can be reset by undoing the cap and
pressing the left hand button located on the facia panel. (See Fig. 1).
If the overheat thermostat persistently cuts out then your boiler
requires attention and you should call either your installer or a service
engineer.
The flue gas thermostat will operate to protect the plastic flue
system from high temperatures.
This can be reset by undoing the cap and pressing the right hand
button located on the facia panel.
If the flue gas thermostat persistently cuts out then your boiler
requires attention and you should call either your installer or a service
engineer.
