WEATHER COMPENSATION
When the Weather Compensation option is fitted to the
system then the Central Heating Temperature Control knob
(E) 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 Domestic Hot Water temperature control knob (F) to
‘boiler off’.
TO RESTART THE BOILER
Repeat the procedure detailed in ‘To light the boiler’ (refer to
page 7). Set the Domestic Hot Water temperature control
knob (F) to between 40ºC & 65ºC, refer to colour screen
whilst adjusting.
FROST PROTECTION
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls at a reduced
temperature setting. For longer periods, the entire system
should be drained.
If the system includes a frost thermostat then the timer can be
left off. 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, the following display will appear;
OVERHEAT LOCKOUT
