OTHER FEATURES
5.8
The following additional features are included in the appliance
specification:
ANTI-CYCLE DEVICE:
When the appliance cycles on its central heating control thermostat, a
slow cycle device operates. The timer (set to 5 minutes) is activated after
the end of each burn cycle to prevent rapid cycling of the burner.
ANTI PUMP SEIZURE DEVICE:
Providing that a power supply is maintained and the appliance ON/OFF
switch is ON, the pump will operate for at least 20 seconds in every 23
hours (regardless of heat demand) to prevent pump seizure during
periods where the appliance is not used.
CH SOFT START DEVICE:
After every burner start, in CH mode, the burner output stays at low for
3 minutes, to ensure smooth heat up of the system and maximum
efficiency.
DHW PRE-HEAT: (CBX appliances only)
DHW
Comfort
selected: With no demand for DHW the appliance will fire
periodically for a few seconds to maintain the DHW plate heat exchanger
in a heated condition. This feature will automatically adjust to the user's
habitual requirements. Thus during long periods of no DHW draw-off,
e.g. overnight, no pre-heat is provided. With DHW
Economy
selected, no
pre-heat is provided.
KEEP-HOT FACILITY (EDEN CBX appliances only)
This feature is designed to provide hot water very quickly without
wasting too much water. Therefore you may notice that after EVERY hot
water draw-off the burner may stay on for a short period of a few
seconds. This is to pre-heat the hot water circuit and prepare the
appliance for the next hot water draw-off.
This feature applies in both the 'Comfort' and 'Economy' modes.
OPTIONAL - HOT WATER DELAY PERIOD (EDEN CBX appliances only)
After every hot water draw-off the appliance may stay in this mode for
a few minutes, (if selected), even though a central heating demand is
present (LED 3 & 4, as shown in the user manual, will be off during this
period). This feature reduces the hot water outlet temperature
fluctuations between draw-offs. This feature is particularly handy when
having a shower.
In households with many hot water taps or larger families this feature
could cause some unwanted delays in providing central heating. To
override the few minute delay, briefly turn the CH control knob or room
thermostat (if fitted) and the appliance will change over to CH almost
immediately, (at least 1 minute after last burner cycle).
SERVICE MODE:
The appliance enters the SERVICE mode by turning the control knob to
'SERVICE' (full clockwise). The two LED's above the knob are now
flashing. In this mode the appliance runs at the minimum CH output.
This mode allows the gas valve offset and CO
2
emissions to be
measured.
USER INSTRUCTIONS
5.9
Upon completion of commissioning and testing the system, the installer
must instruct the user in how to operate the appliance by drawing the
user's attention to the following.
a)
Give the 'Users Instructions' to the householder and emphasise their
responsibilities under the 'Gas Safety (Installation and Use)
Regulations or rules in force.
b)
Explain and demonstrate the lighting and shutdown procedures.
c)
Advise the householder on the efficient use of the system, including
the use and adjustment of all system controls for both CH and DHW.
d)
Advise the user of the precautions necessary to prevent damage to
the system, and to the building, in the event of the system remaining
inoperative during frost conditions.
e)
Explain the function of the Reset button, and how to reset the
appliance. Emphasise that if cutouts persists, the appliance should
be turned off and the installer or service engineer consulted.
f)
Stress the importance of an annual service by a registered heating
engineer.
g)
The electrical mains supply to the appliance must remain ON and
the ON/OFF switch must be left ON for the frost protection circuit to
operate.
