7.6 FAN
MAXIMUM
SPEED
SETTING
(FOR
FAN
AUTO
MODE
ONLY)
You can set the maximum speed of the fan if you choose "fan operation mode" as auto as
described in the previous page. Control panel allows you to set the maximum speed in fan
modulation mode. If you feel the air is too much for your chimney installation and fuel to be
loaded, then you may decrease the maximum speed of fan. In this case, fan will be operated
between minimum speed and the maximum new speed you set. This feature will help the boiler
save on fuel consumption.
If you press MENU button once again, thermostat setting will be over, and the menu swtiches
to the next set parameter sub-menu. Control panel leaves the MENU mode if you wait for 10
seconds without pressing any button, and goes back to normal operation.
7.7 AUTO
FAN
SWITCH-OFF
FEATURE
When power is turned on by ON/OFF button of control panel, fan will automatically start no
matter what the boiler temperature is. Then, fan will be operated according to your
adjustments, that is modulated by electronic board between a minimum speed and a maximum
default or re-set speed by the user. Fan is automatically switched-off when desired boiler outlet
temperature is reached.
If boiler outlet temperature falls below 40
o
C, electronic board keeps on operating fan as long
as a pre-set safety time is elapsed. If boiler temperature does not exceed 40
o
C again during
this safety time, then control panel assumes that there is no fuel in combustion chamber, and
fan will be swtiched off. After this safety time, if boiler outlet temperature is over 40
o
C again
for any reason, fan will be switched on again. However, we recommend that you should reset
the control panel by pressing ON/OFF button ONCE in that case.
Default value for safety time is 45 minutes. But you can re-adjust this safety time between 5
minutes to 90 minutes by 5 minutes intervals. To re-adjust safety time:
Pump will operate as long as boiler
outlet temperature is above 40°C. Pump is always kept
switched off when
boiler temperature is below 40°C, in order to prevent condensation and
save energy. Control panel does not allow re-set on pump start temperature.
