4.6.1
Flow temperature set point during forced part load ( )
Adjustable from 20 °C to 90 °C.
4.6.2
High limit thermostat ( )
Adjustable from 90 °C to 110 °C (
This value sets the high limit temperature at which the boiler will shut
down in a lock out condition requiring manual intervention.
4.6.3
Fan speed at full load HTG ( )
Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm for
the 115 and 1200 to 6000 for the 65). This value sets the maximum
output of the boiler.
4.6.4
Fan speed at part load (HTG and DHW -
Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm for
the 115 and 1200 to 6000 for the 65). This value sets the minimum
output of the boiler.

Starting point modulation ( )
Adjustable from 5 °C to 30 °C.
This value sets the flow/return
modulation begins. If the

This value will prevent the flow temperature exceeding this

The factory default should be correct for most installations. Changing
this value should only be carried out on advice from the service
engineer. Do not change the factory default for the minimum output
(parameter
), in cases of minimal flow.
NOTE: Installations with low flow problems would benefit by reducing
this set point to force modulation to begin sooner and minimise boiler
off time.
