Timer :
The operational time periods may be set as follows:
• Ro
tate the clock actuator mechanism clockwise, by hand, until the arrow indicates the
current time, see
fi
gure 5. The example shows the current time is set
at 21:05.
• The time is set in 24 hour
format, e.g. the time for 1pm would be
13.
• Se
lect the boiler “On” times by pushing the black tappets to the
outside.
Figure 5
• Se
lect the ‘Off’ times by pushing the black tappets
towards the centre of the clock.
The clock operation can be set by the selection switch, which has three positions:
4.
I (Up) position: The boiler is controlled by the function switch (3, Figure 18) and operation
is independent of the clock tappets.
5.
(Mid) position: The boiler is controlled by both function switch and clock tappets.
6.
0 (Down) position: The boiler is off independent of the function switch.
4. LCD Display Screen:
While giving the operational status of the boiler and water
temperature, to aid in fault diagnostics the control unit has a built in facility that automatically
indicates a fault status. If more than one fault simultaneously occurs, then only the highest
priority fault is displayed. (Figure 4)
Figure 4
4.1. Flame indication
: When ignition occurs,
fl
ame symbol (1) is shown.
4.2. Re-set symbol
: When reset symbol (3) is showed with fault code, the boiler will need
to be re-set. To re-set the boiler, the function switch must be switched to
position and
after 30seconds turn back to its previous (summer or winter) position. If the fault continues to
occur seek advice as to curing the problem.
4.3. Central Heating Mode :
When selecting winter mode and working at CH mode, system
shows radiator symbol (symbol 5).
4.4. Digits :
Digits (symbol 6) shows CH temperature, fault codes etc.
