GENERAL
OPERATION
With no call for CH the boiler fires only when DHW is
drawn off, or periodically for a few seconds without any
DHW draw-off, in order to maintain the DHW calorifier in a
heated condition.
When there is a call for CH, the heating system is supplied at
the selected temperature of between 40
o
C and 82
o
C, until
DHW is drawn off. The full output from the boiler is then
directed via the diverter valve to the calorifier to supply a
maximum DHW draw-off of 10 l/min at 35
o
C temperature rise.

At low DHW draw-off rate the maximum temperature is limited to
60
o
C by the modulating gas control.

The boiler features a comprehensive diagnostic system
which gives detailed information on the boiler status when
operating, and performance of key components to aid in
commissioning and fault finding.
