4.2.2 Checking the water contents
Fig. B.4 Checking the water contents
• Check the water contents of the system on the pressu-
re gauge (1).
The needle on the pressure gauge should be within
the green band (between 1 and 1.5 bar). If the needle
displays a value below 0.8 bar when the appliance is
cold, follow the instructions left by your installer to
refill the system.
Alternatively, your installer should be called to refill
the system.
4.3 Domestic hot water operation
The boiler should only be used when the heating system
contains water. Use of the boiler without water may
cause damage to the boiler or its components.
4.3.1 Setting the maximum domestic hot water
temperature control (ecoMAX 800 series only)
Fig. B.5 Domestic hot water operation
• Turn the main switch (2) to the “l” position.
• The display will show the boiler flow temperature
which indicates electrical power to the boiler.
• The domestic hot water temperature can be adjusted
using the hot water temperature control (3).
• Turn the control clockwise to increase the temperature
and anti-clockwise to decrease the temperature.
Note!
This control adjusts the maximum domestic hot
water temperature. If adjusting the control
upwards appears to have no effect on the tem-
perature, then the boiler is already operating at
full output for the selected flow rate.
Attention!
If you live in a hard water area please do not set
the control knob above the mid (12 o’clock) posi-
tion to prevent excessive scale formation (fig.
B.5).
4.3.2 Warmstart operation (ecoMAX 800 series only)
Fig. B.6 Warmstart operation (ecoMAX 800 series only)
The warmstart facility provides instantaneous delivery of
domestic hot water from the boiler.
When the warmstart system is switched ON the boiler
will automatically light periodically to maintain the inter-
nal temperature of the boiler. When the warmstart
system is switched OFF a short delay may be experien-
ced in obtaining hot water at the tap.
• The warmstart system is activated by turning the hot
water temperature control knob (1) clockwise to positi-
on a (see fig.B.6). Now select the required temperatu-
re, e.g. setting b
An illuminated "
" symbol appears on the boiler dis-
play.
The boiler will now provide instantaneous delivery of
hot water directly when a hot water tap is turned ON.
