OPERATING PARAMETERS
The Eclipse boiler is supplied with built-in
parameter defaults (see 2.11), the following
procedure can be used if any parameters require
to be adjusted or changed.
●
Press the MODE button until a FIXED decimal
point appears in LED 1 (see fig. 16).
●
Press the STEP button until the desired
parameter is shown in LED 1.
●
Using the +/- buttons, change the parameter
value (shown in LED 2).
●
Press the STORE button to save the new value.
●
Press the MODE button until no decimal point
is shown.
5.9
FUNCTIONAL PARAMETERS
These parameters should only be changed or
adjusted by the commissioning engineer or service
technician. To change or adjust the functional
parameters, it is necessary to access the
appliance engineer mode.
●
Press and hold the MODE and STEP buttons
simultaneously, LED 1 should now show “C”
(see fig. 17).
●
Whilst continuing to hold down the MODE and
STEP buttons, using the +/- buttons, adjust
LED 2 until it shows “33”.
●
Press STORE.
●
LED 2 will now flash once, the MODE and
STEP buttons can now be released.
●
Press the MODE button until it shows a FIXED
decimal point (see fig. 16).
●
Press the STEP button until it shows the desired
parameter (LED 1).
●
Adjust the value (LED 2) using the +/- buttons
●
Press STORE to save the new setting.
●
Press the RESET button to exit the appliance
engineer mode.
IMPORTANT
Under no circumstances should any parameters
- other than those shown - be changed or adjusted.
Please refer to section 7 before making any
adjustments to the fan speed parameters of the
boiler.

RANGE RATING
The output of the boiler is automatically adjusted
by a continuous air/gas modulation system. The
system is controlled by the NTC thermistors (flow
& return temperature sensors) which ensures
stability of temperature irrespective of load
conditions. However the appliance also has a
range rating facility which can be used to limit the
maximum output if required. Please refer to section
7 for more details.

SETTING THE SYSTEM DESIGN PRESSURE
The design pressure should be a minimum of 1
bar and a maximum of 1,5 bar.
The actual reading should ideally be 1 bar plus
equivalent height in metres (0,1 bar = 1 metre) to
the highest point in the system above the base of
the appliance (up to the maximum of 1,5 bar
total).
N.B. The safety valve is set to lift at 3 bar/30
metres/45 psig.
To lower the system pressure to the required
value, pull lever on head of safety valve to release
water until the required figure registers on the
pressure gauge (see fig. 1).
5.12
REGULATING THE CENTRAL HEATING
SYSTEM
Fully open all radiator and circuit valves and run
the appliance for both heating and hot water until
heated water is circulating. If conditions are warm
remove any thermostatic heads. Adjust radiator
return valves and any branch circuit return valves
until the individual return temperatures are correct
and are approximately equal.
