operation
control of Water Temperature
The boiler controls the central heating radiator temperature to a
maximum of 80
o
C, adjustable via the temperature control (A).
The Project Heat is a high efficiency condensing boiler which is
most efficient when operating in condensing mode.
The boiler will operate in this mode if the temperature control (A)
is set to the ‘e’ position (economy mode). This control should be
set to maximum for very cold periods
Weather compensation
When the Weather Compensation option is fitted to the system
then the CH Temperature Control (A) becomes a method of
controlling room temperature. Turn the knob clockwise to
increase room temperature and anti-clockwise to decrease room
temperature. Once the desired setting has been achieved, leave
the knob in this position and the system will automatically achieve
the desired room temperature for all outside weather conditions.
To shut down the boiler
Set the mode control knob to OFF.

To relight the boiler
Repeat the procedure detailed in ‘To light the boiler’.
Frost protection
If no system frost protection is provided and frost is likely during
a short absence from home, leave the heating controls (if fitted)
at a reduced temperature setting. For longer periods, the entire
system should be drained.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON, with
the boiler thermostat left in the normal running position.
Boiler Overheat Protection
The boiler controls will shut down the boiler in the event of
overheating. Should this occur, a fault code will be displayed
Refer to fault chart.
Flame Failure
Should this occur a fault code
will be displayed. Refer to fault
chart.
