*NOTE: see Par. 6.1.4 for values over two digits

6.6.1 Flow temperature set point during forced part load ($)

Adjustable from 20 to 90°C.
This value will prevent the flow temperature exceeding this temperature during the part
load time.

6.6.2 High limit thermostat (%)

Adjustable from 90 to 110°C (!0).
This value sets the high limit temperature at which the boiler will shut down in a lock
out condition requiring manual intervention.
Note: this parameter will have an effect on the minimum flow rate requirement, see
Par. 7.4.7.

6.6.3 Fan speed at full load HTG (^)

Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm). This value sets
the maximum output of the boiler.
6.6.4 Fan speed at part load (HTG and DHW - &)
Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm). This value sets
the minimum output of the boiler.

6.6.5 Starting point modulation (*)

Adjustable from 5 to 30°C.
This value sets the flow/return dT point at which the control modulation begins. If the
dT continues to rise, at 40°C the boiler will be at minimum output (parameter &), at
45°C the boiler will shut off (code b#), see Par. 6.4).
The factory default should be correct for most installations. Changing this value should
only be carried out on advice from the service engineer. Don't 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.
