*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, factory default 79°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), factory default 100°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. 1200 to 5300 rpm), factory default

62 (100%). 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. 1200 to 5300 rpm), factory default

12 (18% output). This value sets the minimum output of the boiler.

6.6.5 Starting point modulation (*)

Adjustable from 5 to 30°C, factory default 25°C.

This value sets the flow/return dt point at which the control modulation begins. If the Δt

continues to rise, at 40°C the boiler will be at minimum output (parameter &), at 30°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 &), is 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.
