The manual operation mode enables the boiler to be run
manually for a long period. Manual operation should be used for
situations where the controller has not been installed yet, or
where the controller is out of order. See also section 22,
"Manual Operation menu", page 15.
A maximum heating system supply temperature in accordance
with the setting of the space heating water temperature knob
(section 14, [8]) on the BC 10 applies during the flue gas test,
service and manual operation.
DAMAGE TO THE INSTALLATION
with floor heating: by the pipework being over-
heated.
 Use the space heating water temperature
knob [8] to limit the maximum heating system
supply temperature to the permitted heating
system supply temperature of the floor heating
circuit. This is usually approximately 104 °F
(40 °C).
DAMAGE TO THE INSTALLATION
due to frost while manual operation is switched on.
After a power failure or after switching off the main
voltage, the heating system may freeze since man-
ual operation is no longer active.
 Re-activate manual operation after switching on
the heating system, so that the system is perma-
nently in operation.
