Temperature Control
1.
Central Heating:
The central heating hot water
flow temperature can be adjusted between 30° C
(± 5° C) minimum and 85° C (± 5° C) maximum.
2. Turn the control knob clockwise to increase the
temperature (Fig. 8).
3. In normal winter usage we recommend that the
central heating temperature be set at maximum.
4.
Domestic Hot Water:
The temperature of the
domestic hot water can be adjusted by turning the
control knob clockwise to increase up to a
maximum of 65° C (Fig. 9).
5. The temperature of the water is also dependent
on the water flow rate and the temperature of the
mains water coming into the house.
6. By slightly reducing the flow from the tap the
temperature will increase up to the maximum if
required.
7. The flow rate can be reduced down to as low
as 2.5 litre/min. The boiler will still recognise the
need to heat the water.
2.4
Safety Thermostat
1. Your Baxi Combi 80Eco is fitted with an
additional safety device, which shuts down the
boiler in the event of the system or the boiler
overheating.
2. If the device operates, the boiler will shut down.
To reset:
Contact your Service Engineer - the
reset button is inside the appliance and resetting
by the user should not be attempted.
3. The cause of operation of the safety thermostat
should be determined by your Service Engineer.
2.5
Flame Failure Reset
1. The red flame failure neon (
) will illuminate
in the event of the burner failing to light, or when
incomplete lighting of the burner occurs (Fig. 11).
2. Turn the selector switch fully anti-clockwise
against the spring pressure to the reset position
(
R
) and release (Fig. 10). Set the selector switch
to the required position to light the boiler.
3. If the flame failure neon illuminates repeatedly
a fault is indicated. Your Service Engineer should
be contacted as soon as possible.
